There are two delivery conditions for weathering steel sheets and weathering steel coils. According to the production process and physical properties, it is divided into hot rolled weathering steel and cold rolled weathering steel. Domestic steel mills producing weathering steel include BaoSteel, Wuhan Iron and Steel, Maanshan Iron and Steel, Handan Iron and Steel, Angang Steel and Tangshan Iron and Steel.
Represents weathering steel grades: 05CuPCrNi-A, 09CuPCrNi-A, SPA-H, SPA-C ,B480GNQR, Q400NQR1, Q450NQR1, Q550NQR1, etc.
2.Effect of alloy elements on Corten Steel weather ability
Weathering steel has good resistance to atmospheric corrosion compared to ordinary carbon steel. This is because the alloying elements act to reduce the electrical conductivity of the rust layer and hinder the rapid growth of corrosion products. Corrosion resistance is characterized by a significant corrosion resistance after long-term use. The alloying elements which can improve the atmospheric corrosion resistance of steel should satisfy the following conditions: 1 the solubility in iron is greater than the solubility in the rust layer; 2 can form a solid solution with iron; 3 can increase the potential of steel
