ASTM A242 Weathering Steel Plate

PRODUCT DESCRIPTION ASTM A242 NH carbon steel plate is also known as Weather Resistant Steel Sheet, Weather Resistant Steel Plate.Weather-resistant structural steel is atmospheric corrosion-resistant steel, which belongs to low-alloy high-strength structural steel. According to its main characteristics, it is divided into high-weather-resistant structural steel and weather-resistant steel for welded structures. High-weather-resistant structural steel is made by adding a small amount of copper and phosphorus to steel , chromium and nickel elements to form a protective layer on the surface of the metal collective to improve the atmospheric corrosion resistance of the steel, and a small amount of molybdenum, niobium, vanadium, titanium, zirconium and other elements can be added to refine the grains and improve the performance of the steel. The mechanical properties of steel, improve the strength and toughness of steel, reduce the brittle transition temperature,…
