Recently, a symposium on the celebration of the 70th anniversary of the founding of the People's Republic of China by the iron and steel industry was held in Beijing Convention Center. The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, BBN sa573 grade 70 high strength structural steel Steel Staff sang songs to the mark the 70th victory anniversary. In the last of September, Henan BBN Steel organized all employees to sing ""My Country and I"" and made a film.
Wear-resistant steel plate is a kind of construction material with good wear resistance and high toughness. sa573 grade 70 high strength structural steel, wear-resistant steel plate plays an important role in many industries in daily use. However, what is wear-resistant steel plate? Where is it used? The wear-resistant layer is the main component of the wear-resistant steel plate. The material used to make the wear-resistant layer is mainly titanium alloy. In addition, other materials such as manganese, nickel, molybdenum, and niobium may be added. The coordination of all materials is to maintain or enhance the wear resistance of the wear layer.
sa573 grade 70 high strength structural steel, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.
