Steel Dynamics Reports Strong Results for Q3 of 2021

Strategic Research Institute
Published on :
19 Oct, 2021, 5:56 am

US steel maker Steel Dynamics Inc has reported record third quarter 2021 net sales of USD 5.1 billion and net income of USD 991 million. Steel Dynamics In, Chairman & Chief Executive Office Mr Mark D. Millett said "During the third quarter, steel demand remained strong as product pricing continued its positive trajectory across our entire steel platform. Higher realized steel selling values drove significant metal spread expansion and were again most prominent within our flat roll steel operations, as continued demand strength and low customer inventories persisted throughout the supply chain and supported prices. Domestic steel consumption was strong from the automotive, construction, and industrial sectors, while the energy sector continued to show signs of recovery. Our segment operating results continue to be outstanding.”

Third Quarter 2021 Highlights:

Record steel fabrication shipments of 211,000 tons

Record steel and steel fabrication operating income of USD 1.4 billion and USD 89 million, respectively

Year-to-Date September 30, 2021

For the nine months ended September 30, 2021, net income was USD 2.1 billion, with net sales of USD 13.1 billion, as compared to net income of USD 363 million, with net sales of USD 7.0 billion for the same period in 2020

Outlook - "Current market conditions are in place to support solid domestic steel demand for the fourth quarter and into 2022. Order entry activity continues to be robust across our businesses. We continue to see strong steel demand coupled with moderating, but still historically low customer inventories throughout the supply chain. These dynamics support continued elevated steel selling values. Domestic steel demand remains solid in our automotive, construction, and industrial end markets. We believe this momentum will continue and that our fourth quarter consolidated earnings could represent another record performance. Based on strong domestic steel fundamentals and customer confidence, we continue to be positive regarding North American steel market dynamics. This constructive environment coupled with our strategic growth initiatives provide firm drivers for our further growth in the coming years.”

GMS Market Commentary on Ship Breaking in Week 41

Strategic Research Institute
Published on :
19 Oct, 2021, 5:58 am

World's leading cash buyer of ships for recycling GMS said that “The last quarter jump in local steel plate pries and at varying degrees seems to have swept across all major recycling markets (including China) this week. The jump in levels varied from as little as USD 5/Ton from the Chinese market, all the way to USD 30/Ton on the Turkish end, with the sub-continent markets bridging the gap. Despite the dry sector continuing to perform surprisingly well and keeping the markets starved of bulker and container units, as holidays descend upon India and China, it is time to take stock of what has been another busy quarter of mostly tanker scrapping, as this particular sector looks to get back on its feet next year, following a heavy year of recycling. Local port positions across all sub-continent markets confirm this, given the number of wet units being delivered to Recyclers on a weekly basis.”

GMS said “Overall, it is expected to be another frantic finale to the year, as prices remain firm at historical levels at or above USD 600/LDT and tanker charter rates (for the most part) remain in the doldrums, providing an alternate lifeline to the ship recycling sector.”

GMS added “We have seen very few bulkers and containers for a majority of this year – with even older 90s built units passing surveys to continue trading, such has been the strength of current freight rates.”

GMS also aid “Whilst steel remains firm and the currency in India, Pakistan and Turkey have been facing their shares of wobbles over the last couple of weeks, we do not anticipate ship recycling prices to decline significantly any time soon.”

GMS Pricing

India/Bangladesh/Pakistan – Week 41, Unchanged

Dry Bulk – USD 560-590 per LDT

Tankers - USD 570-600 per LDT

Containers - USD 580-610 per LDT

Marienhuette Graz Implement Al Solution in EAF Steel Production

Strategic Research Institute
Published on :
19 Oct, 2021, 6:02 am

Austrian rebar manufacturer Stahl und Walzwerk Marienhuette Graz has successfully commissioned Smart Steel Technologies’s SST Temperature Al software. The software solution is now integrated online in the production process. Thus, temperature control from EAF to continuous casting is more precise. Process stability is optimized across all stations. Thus, Marienhuette minimizes temperature buffers and consequently lowers the tapping temperature in the EAF. The result is permanent energy and C02 savings as well as increased process stability.

The commissioning of the software took three months only due to an intense collaboration with Smart Steel Technologies. The Software reliably guides the operators through their processes.

Stahl und Walzwerk Marienhütte GmbH CTO Mr Herbert Fohringer said “In the current challenging economical situation, we consciously did invest in the optimization of our temperature control using Artificial Intelligence technology. After a successful Go-Live Marienhuette is now increasing process stability even further, thus significantly reducing energy consumption and C02 emissions. The development and commissioning of the software was carried out in good cooperation, quickly and with low personnel costs.”

Severstal Reports Improvement in Q3 & 9M Performance

Strategic Research Institute
Published on :
19 Oct, 2021, 6:04 am

Russian steel maker Severstal announced 9% QoQ surge in revenue and net profit in July-September quarter to USD 3,206 million & USD 1,237 million respectively as steel production & sales improved by 4% QoQ to 2.878 million tonnes & 1% QOQ to 2.694 million tonnes. Severstal CEO Mr Alexander Shevelev said “In Q3 of 2021, we saw the first signs of stabilization in the steel market. Iron ore prices fell nearly USD 100 per tonne from record levels due to lower demand in China due to limited steel production. As we expected, spot steel prices also declined from their highs in Q2 of 2021. Semiconductor shortages lead to disruptions in car production in Europe. As a result, there was a decrease in demand for steel and a shorter delivery time for metal products, which restores the balance of supply and demand in the steel market. The introduction of export duties in Russia led to a drop in domestic prices for hot-rolled steel to a level below export parity after deducting the duty. However, sales growth coupled with higher average realized prices, due to the time difference between spot and actual prices, allowed the Company to achieve record financial results.”

January- September 2021 Performance

Pig iron production increased by 12% YoY to 8 million tonnes due to the commissioning of DP-3 in December 2020. Steel output increased to 8.62 million tonnes up 1% YoY, amid the launch electric arc furnace No 1 in April 2021, as well as a result of the completion of the modernization of the converter shop and foundry machines.

Steel sales declined slightly to 8 million tonnes down 1% YoY. Sales of semi-finished products quadrupled YoY to 1.07 million tonnes following an increase in pig iron and steel production during repairs at a hot-rolled mill. Sales of hot-rolled steel (including thick plate) decreased by 20% YoY, mainly due to a large-scale modernization of one of the batch furnaces.

Sales of high value added (GVA) products increased by 4% YoY, driven by higher sales of cold-rolled steel up 19% YoY to 0.79 million tonnes and galvanized steel up 74% to 0.23 million tonnes.

As Numsa’s wage strike in South Africa’s steel and engineering sector entered its third week, Steel and Engineering Industries Federation of South Africa’s Council, given that Solidarity and UASA have accepted the final offer, has unanimously endorsed a recommendation that affiliated member companies begin implementing the final offer. SEIFSA said “Whilst we request individual member companies to be guided by this recommendation, we nevertheless implore member companies to be guided by circumstances and the prevailing industrial relations climate on each and every shop floor.”

SEIFSA chief Mr Lucio Trentini said “As the strike and lock out continues into another week, we have consistently communicated that the longer the posturing and refusal to settle on the part of NUMSA continues, the more jobs will eventually be lost in an industry that should instead be doing everything possible to protect each and every valuable job in the sector.

SEIFSA has shared the details around the plan of action emanating from urgent discussions with the National Joint Operational and Intelligence Structure, which is the coordinating body of all security and law enforcement agencies throughout the country, including the SA Police Force, SANDF and Metro Police, that took place over the weekend.

The National Union of Metalworkers of SA, the country’s largest union with about 432,000 members, last week rejected a revised wage offer by the Steel and Engineering Industries Federation of SA of 6% from the previous 4.4%. Of the five trade unions that have bargained with SEIFSA, Solidarity and UASA have indicated their acceptance of the offer. SAEWA have confirmed their rejection of the final offer but are not out on strike. NUMSA and MEWUSA remain on strike.

South Korean media reported that Posco has succeeded in producing special steel pipes for hydrogen transportation by using a new steel material that greatly improved the lifespan and safety of welded connections to withstand rupture or corrosion and will supply them for the first time to the city of Ansan in Gyeonggi Province of South Korea. The new products from Posco are made to overcome the safety problem, can withstand temperatures as low as minus 45 degrees Celsius and are wider in diameter

Until now, South Korea has relied on imported, small-caliber seamless steel pipes with a width about 15 centimeters for hydrogen transportation. Bigger pipes, as wide as 20 centimeters, are needed to carry the big volume of hydrogen transfer needed in the hydrogen test bed cities such as Ansan. But imported products with welded parts were always used on a limited basis for safety issues

Ansan was designated as a hydrogen test bed by the Transport Ministry in 2019. The southern cities of Ulsan as well as Jeonju and Wanju in North Jeolla Province have also been chosen by the ministry for pilot projects to adopt hydrogen to power living facilities and public transportations there.

AMI Automation announced that after a project finalized in the Kyushu plant, Tokyo Steel confirmed the successful evaluation and final acceptance of the AMI EAF Optimization System in their 420 tonne 256 MVA DC Electric Arc Furnace at Tahara works producing hot coils, as part of continuous improvement in their still new installation. This particular SmartFurnace system project began in late 2020, and was effectively concluded and accepted on March 2021 after designing, manufacturing, installation, commissioning and an evaluation made over a continuous operation period.

The installation in the ultra high power Twin Cathode DC EAF with continuous scrap feeding included the DigitARC PX3 Electrode Regulator, the SmartARC Electrical Energy Optimization System, and the Continuous Scrap Feeding Module controlling the raw material conveyor.

The guaranteed goals that were proven at the end of the evaluation were the increase of the Power Input and the decrease of flicker levels, a double challenge derived from the furnace size and the network conditions in the Tahara geographic area. Additional benefits were also obtained in Power On Time due to an efficient use of electrical energy, with the dynamic control of the electrical profiles and raw material input of the SmartFurnace technology.

The unexpected challenge of the global COVID crisis forced both Tokyo Steel and AMI to adapt the project execution format, extensively relying on remote access and the constant support of the Tokyo Steel team on site. As such, the first ever remote Kick Off Meeting for an AMI project of this kind was carried out, as well the continuous adjustment, tuning and monitoring of the furnace supported remotely by the AMI project team from locations in Japan, North America and Europe, an ongoing cooperation that aims to continuously improve the operation.

Ind-Ra Sees China’s Energy Crisis Benefitting Indian Steel Mills

Strategic Research Institute
Published on :
20 Oct, 2021, 6:10 am

China’s worsening energy situation has impacted not only its commercial and industrial segments and forced factories to cut production but it is also threatening to impact the growth of the country's vast economy and place increased strain on global supply chains. India Rating has opined in its Steel Outlook that the China is likely to cut its steel output in H2 of FY21 after having recorded crude steel production of 560 million tonnes in H1 of FY21 up 10.5% YoY, to reduce industrial carbon emissions and improve air quality. The fall in China’s steel output and India’s imports of intermediate steel products would benefit Indian steel players by way of lower import risks and greater export opportunities.

It said “The changes in China’s energy policy related to the price band for power could cause a key structural shift within the sector, thereby supporting steel prices in the international as well as domestic markets. Furthermore, lower Chinese exports, the prevailing trade tensions between China and the western world, the Biden administration’s proposal for a USD2 trillion infrastructure bills and healthy steel demand from the EU would collectively prove beneficial for Indian steel players. However, while the overall steel prices will rise due to curbs on Chinese production and high input costs, the benefits to Indian players will be limited on account of high logistics costs and challenges such as container shortages.”

Researchers Develop Alloy Which Repairs itself When Damaged

Strategic Research Institute
Published on :
21 Oct, 2021, 5:31 am

The results of experiments at Rice and the South Dakota School of Mines and Technology, found in Advanced Materials, could be a boon for infrastructure, buildings, bridges and anything above or below the water made of steel, that requires protection from the elements. Scientists at Rice University have cooked up a new alloy with a unique and diverse set of attributes that could prove highly effective at protecting steel from corrosion. The novel coating not only prevented rusting in submerged slabs of common steel, but is flexible and proved capable of healing itself when damaged. The new anti-corrosion coating is made of a lightweight sulfur-selenium alloy, and according to the material scientists behind it, combines desirable qualities from currently available solutions. This means an ability to block moisture and chlorine like zinc- and chromium-based coatings, an ability to protect steel under seawater-like conditions like polymer-based coatings, and an ability to fend off microbe-induced corrosion.

This was established through a series of experiments, the first of which saw small slabs of common mild steel coated with sulfur-selenium alloy and submerged in seawater for a month, along with an uncoated slab of steel as a control. While the bare steel rusted significantly, the coated steel exhibited no change in color and proved highly resistant to oxidation.

Next, the scientists tested it out against sulfate-reducing bacteria that is known to greatly accelerate the corrosive process. Coated and uncoated samples were exposed to plankton and biofilms, and again the alloy helped to protect the steel underneath. According to the scientists, the coating offered an "inhibition efficiency" of 99.99 percent.

Perhaps most impressively, the team found the alloy to have powerful self-healing properties. When a film of it was cut in half and the two pieces were placed next to each other on a hot plate, they reformed into a single, foldable film within two minutes when heated to 70 degree Celsius. Pinholes could also be repaired by heating the material to 130 degree Celsius for 15 minutes, with the healed material proving just as effective at protecting steel as undamaged, original coatings.

Mechel Steel Beam Used for Construction of Waste Processing Plants

Strategic Research Institute
Published on :
21 Oct, 2021, 5:34 am

Mechel Group's metal trading company Mechel Service has supplied more than 2,000 tonnes of beams for the construction of three facilities: two waste processing plants and an energy recovery plant in the Moscow Region, which will operate as a single complex. Mechel-Service supplied a beam produced by the Chelyabinsk Metallurgical Plant to the facilities in Kolomna, Kashira and Svistyagino. The steel I-beam has a high load-bearing capacity with a low specific weight, its flanges distribute the load and reduce the risk of structural failure. For the production of an I-beam, carbon or low-alloy steel grades are used. Low alloy steel structures can also be used in northern sites in low temperature areas. Earlier, Mechel-Service also supplied an ordinary sheet produced by Chelyabinsk Metallurgical Plant for the manufacture of boiler frames for waste energy utilization.

Steel structures of buildings of enterprises in Kolomna, Kashira and Svistyagino were welded from Mechel's rolled products. The plants are being built by RT-Invest, a Rostec structure. Waste processing will take place within the framework of an integrated waste management system, at first the fractions will go through the stage of industrial sorting and only those waste that cannot be recycled will be processed into energy. The plant in Svistyagino is being built using the technology of the Swiss-Japanese concern Hitachi Zosen Inova. Foreign experts are actively monitoring the progress of construction. HZI has already built more than 500 such factories around the world. According to this technology, instead of burial at landfills, waste is converted into "green" electricity, since after their combustion in boilers, steam will be generated, which is sent to a turbine.

There will be four such factories in the Moscow Region. Another plant for thermal waste processing is being built in Tatarstan. The total capacity of 5 enterprises will amount to 3.35 million tons of waste per year.
