Wear resistant steel plate has excellent low temperature toughness, so it can be used in large welding structure and low temperature environment. Moreover, there are many kinds of wear-resistant steel plate, EN 10083-3 30CrNiMo8 alloy steel in operation control, especially in the factory building. Wear resistant steel plate is widely used in construction and steel pipe industry, which is one of the most important products in the industry. It is composed of low-carbon steel plate and alloy wear-resistant layer. The alloy wear-resistant layer is generally 1 / 3-1 / 2 of the total thickness.
S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. EN 10083-3 30CrNiMo8 alloy steel, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
