Sulfur is a very harmful element in SMA490AW mechanical properties steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of SMA490AW mechanical properties steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel, such as strength, toughness, ductility, forming, welding and cutting, abrasion, high temperature, fatigue and so on. The weathering resistance of weathering steel is 2-8 times of that of plain carbon steel SMA490AW mechanical properties, and the coating property is 1.5-10 times of that of plain carbon steel. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, etc..
