The JIS SM490C plates elongation from BBN

What is the difference between Q235 steel and Q345 steel? First, strength difference: the lower limit of yield strength of Q235 steel is 235MPA, and the lower limit of yield strength of Q345 steel is 345MPA (Q means "Qu" in Chinese characters, and the later value represents the lower limit of yield strength). Second, the chemical difference: the alloy content of Q235 steel and Q345 steel is different, Q235 steel is ordinary carbon steel, while Q345 steel is low alloy steel JIS SM490C plates.

High quality steel sheet and plate product JIS SM490C plates supply 10.5*1970*7950, 13*1300*4350, 11*1900*12500, 12.5*2870*7100, 11*1870*12500, 10.5*1970*8000, 13*1520*7950, 11*1910*9000, 12.5*2900*8250, 11*1870*13500, 10.5*2350*6200, 14*1440*6100, 11*3100*10000, 13*1510*4850, 11*1870*9300, 11*1570*12000, 14*1800*9750, 11.5*2640*7600, 13*2380*6000, 11*2400*10000.

The company's main steel plate varieties: JIS SM490C plates, boiler pressure vessel plate, low-alloy plate and high-strength plate, bridge plate, alloy plate, carbon steel, wear-resistant plate, pipeline steel, nuclear power steel, wind power and hydropower steel, ship plate, building structural steel, Die steel, military steel plate, hydrogen steel plate and various special steels, etc.

In general, the global manufacturing industry has been seriously impacted by the epidemic, and the foreign epidemic is still in the outbreak period, and its JIS SM490C plates demand recovery still has some time. However, the domestic epidemic situation has come to an end. In addition, the state has repeatedly stressed that the development of traditional infrastructure and new infrastructure needs a lot of steel. And now the return to work is getting better. As of March 20, the return rate of key projects is 89.1%, and the return rate of 11000 key projects in China is nearly 90%.
