ASTM A242 Weathering Steel Plate

ASTM A242 is a high-strength low-alloy steel, which is an atmospheric corrosion-resistant steel in the United States, that is, atmospheric corrosion-resistant steel. A family of low-alloy steels between ordinary steels and stainless steels. Weathering steel is made from ordinary carbon steel. It is made by adding small amounts of corrosion-resistant elements such as copper and nickel. It has the characteristics of high-quality steel in terms of toughness, plasticity, forming, welding and cutting, wear resistance, high temperature resistance, and fatigue resistance. Weather resistance is 2 to 8 times that of ordinary carbon steel. The performance is 1.5 to 10 times that of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance, long component life, thinning and consumption reduction, labor saving and energy saving. Weathering steel is mainly used for steel structures that are exposed to the atmosphere for a long time.…
