steel with a small amount of copper, nickel and other elements. It has the characteristics of excellent steel, such as toughness,
plastic extension, forming, welding and cutting, high temperature, etc. Weather resistance is 2~8 times of ordinary carbon steel,
coating is 1.5~10 times of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, so that the
component is thin and consumption reduction, labor saving and energy saving.
