SMA490BW steel

SMA490BW Weather Resistant Steel is a type of low alloy steel that is designed to resist atmospheric corrosion. It is often used in structural applications such as bridges and buildings, as well as in railway vehicles and other industrial equipment.

The composition of SMA490BW Weather Resistant Steel typically includes elements such as copper, chromium, and nickel, which contribute to its corrosion resistance properties. These elements react with the atmosphere to form a protective layer of rust, which helps to prevent further corrosion of the steel.

Some of the key properties of SMA490BW Weather Resistant Steel include:

Corrosion resistance: SMA490BW steel is highly resistant to atmospheric corrosion, making it ideal for use in outdoor applications.
High strength: The steel has a minimum yield strength of 365 MPa and a minimum tensile strength of 490 MPa, making it a strong and durable material for structural applications.
Good toughness: SMA490BW steel has good toughness and ductility, allowing it to withstand harsh weather conditions and other forms of stress.
Weldability: The steel can be easily welded using common welding methods, making it suitable for use in a variety of construction applications.
Formability: SMA490BW steel can be easily formed and shaped to meet the specific requirements of different applications.
