Q355GNH characteristics
Q355GNH weathering steel, which is resistant to atmospheric corrosion steel, is a series of low alloy steels between ordinary steel and stainless steel. Weathering steel is made of ordinary steel with a small amount of corrosion elements such as copper and nickel. It has the toughness of high-quality steel and plastic extension. , molding, welding, abrasion, high temperature, anti-fatigue and other characteristics.
