Global A573 grade 70 steel sheet crude steel production in March this year increased by 2.6 percent month on month and fell by six percent year on year to 147.1 million metric tons. accordina to the World Steel Association (worldsteel).In the first quarter of this year, global A573 grade 70 steel sheet crude steel production decreased to 443.03 million mt, down 1.4 percent year on year。
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. A573 grade 70 steel sheet, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.
