09CuPCrNi-A Steel

09CuPCrNi-A steel is a type of weather-resistant steel that is designed to resist atmospheric corrosion and provide high strength and good toughness. It is used in various applications such as bridges, buildings, and other structures that are exposed to harsh weather conditions.

The steel contains alloy elements such as copper, chromium, and nickel, which contribute to its corrosion resistance properties. The presence of these elements forms a protective layer on the surface of the steel when exposed to the atmosphere, which helps to prevent further corrosion.

09CuPCrNi-A steel has a minimum yield strength of 345 MPa and a minimum tensile strength of 480 MPa, making it a strong and durable material for structural applications. It is typically supplied in a normalized or controlled rolled condition, which improves its toughness and ductility.
