  • 09CuPCrNi-A/Q355GNHL Weathering Steel Pipe
    09CuPCrNi-A/Q355GNHL Steel Pipe is a kind of Weathering steel pipe in China, which belongs to low alloy steel.
    09CuPCrNi-A/Q355GNHL Weathering Steel Pipe is to add a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to make the steel pipe form a layer of 50-50μm thick dense and non-stick with the base metal The crystalline spinel oxide layer can effectively organize the penetration of oxygen and moisture in the atmosphere into the steel pipe itself, thereby slowing down the corrosion rate and greatly improving the atmospheric corrosion resistance of the steel pipe.
