what is Q355GNH steel, Wear resistant steel plate has good wear resistance:
The chemical composition of the alloy wear-resistant layer is 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%. The macro hardness is HRC56-62 and the hardness of chromium carbide is HV1400-1800. Because the carbides are distributed perpendicularly in the direction of wear, even when compared with cast alloys of the same composition and hardness, the wear resistance is more than doubled.

what is Q355GNH steel, Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.
