Supply the free sa573 gr 70 carbon-manganese-silicon steel density

15CrMo alloy plate is a pearlite structure heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature, and sa573 gr 70 carbon-manganese-silicon steel has certain hydrogen corrosion resistance. Due to the high content of Cr, C and other alloy elements in 15CrMo alloy plate, the steel has obvious hardening tendency and poor weldability. The weight calculation formula of 15CrMo alloy plate: length × width × thickness × 0.00785 = kg / m. Delivery status of 15CrMo alloy plate: hot rolling, controlled rolling, normalizing, high temperature tempering, QT, etc.

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 gr 70 carbon-manganese-silicon steel, 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..
