SA871 Type2 Gr.65 Steel

SA871 Type 2 Grade 65 is a high-strength, low-alloy structural steel plate according to ASTM A871 standard. It is specifically designed for use in bridge construction and other structures that require high strength and resistance to atmospheric corrosion. The steel has a minimum yield strength of 450 MPa and a minimum tensile strength of 485 MPa. The chemical composition is similar to other high-strength, low-alloy steels, but contains a higher amount of manganese and a lower amount of silicon compared to SA871 Type 2 Grade 60.

Weather resistant steel is a low alloy steel. Different from ordinary steel, weather resistant variant steel forms a protective oxide film called ‘patina’ in a appropriate environment. This oxide layer seals the surface and reduces corrosion loss. Weather resistant steel is also referred as weathering steel in market. This type of steel is widely used in construction of bridges and other iconic and architectural structures. The famous bridges like New River Gorge bridge is made of weathering steel.
