The chemical composition of Q345D seamless steel pipe is as follows: C ≤ 0.18, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S≤ 0.025, Nb ≤ 0.07, V ≤ 0.15, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.012, Mo ≤ 0.10, Al ≥ 0.015. sa573 grade 70 structural steel carbon plate, Q345D seamless steel pipe has good comprehensive mechanical properties, low temperature impact toughness, corrosion resistance, cold stamping, machinability and weldability. Q345D seamless steel pipe is widely used in welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, etc..
The wear-resistant layer of wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
