Q355GNH Plate To GB/T 4171 Weathering Steel

Q355GNH weathering steel, that is, atmospheric corrosion-resistant steel, is between ordinary steel and du stainless steel low alloy steel zhi series, weathering steel from plain carbon dao steel add a small amount of copper, nickel and other corrosion-resistant elements and become, with high-quality steel, tough, plastic stretching, molding, welding and cutting, abrasion, high temperature, fatigue and other characteristics; Weathering resistance is 2~8 times that of plain carbon steel, and paintability is 1.5~10 times that of plain carbon steel. At the same time, it is rust-resistant, so that the components of corrosion-resistant life extension, thinning and consumption reduction, labor-saving and energy-saving features.
