What are the characteristics and application of weathering steel

What is weathering steel?
Weathering steel, that is, atmospheric corrosion-resistant steel, also known as corton steel. Its special feature is that when exposed to the natural environment, through the action of air, rain, etc., the surface of the steel will automatically form a corrosion-resistant protective layer without painting protection, the life of the weathering steel material is more than 80 years, it is a low alloy steel series between ordinary steel and stainless steel.

Characteristics and application of weathering steel:
Weathering steel has the characteristics of good toughness, plastic extension; good forming, welding and cutting ability; abrasion, high temperature resistance; and protective rust layer resistant to atmospheric corrosion and fatigue. Weathering steel can be used to manufacture steel structures such as vehicles, bridges, towers, and containers.
