What is SMA570W Weathering Steel？

SMA570W Weathering Steel is known for its superior yield strength of around ≥ 450 MPa and tensile strength ranging from 570–720 MPa. This makes it suitable for demanding structural uses, especially where both durability and load-bearing performance are critical. The alloy composition includes copper, nickel, chromium, and phosphorus, which promote the formation of the protective patina layer and ensure long-term corrosion resistance in outdoor environments.
