china nm500 steel manufacturer plate weldability

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing china NM500 steel manufacturer steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, china NM500 steel manufacturer based on a high starting point and high technology, the company has vigorously developed various steel products china NM500 steel manufacturer and deep-processed parts, steel structures, precision castings, seamless pipes.

By Region: data shows that in the first quarter of Asia, crude steel china NM500 steel manufacturer production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year.

china NM500 steel manufacturer, Hardened wear-resistant plates are gradually annealed at a temperature higher than 250℃ to lose their hardness, which greatly reduces the wear resistance. The welding process will also reduce the hardness near the weld; the wear layer of the bimetal wear plate is of high alloy composition, and there is a secondary hardening effect at a certain temperature, and it can generally work below 650℃.
