What is A572 Gr 60 carbon steel plate sheet equivalent steel grade in China

The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in A572 Gr 60 carbon steel plate sheet etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. A572 Gr 60 carbon steel plate sheet, Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. A572 Gr 60 carbon steel plate sheet, Q420 steel has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. Q420 steel is suitable for power tower, all kinds of crane, heavy truck, oil derrick, high temperature fan, large electric shovel, dump truck and drilling rig, coal mine hydraulic support, steel structure, etc. application.

Since the outbreak of the new crown pneumonia epidemic this year, the Iron and Steel Association has closely followed and found that, with the exception of March, the production and operation of the steel industry has maintained a positive growth despite the low rate of resumption of work and production in other industries. Superimposed on the pull of a series of national policies in the later period, the steel industry effectively supported the development of the national economy.
