ASTM A242 Type 1 Corten Steel is a robust, low-alloy structural steel that excels in resisting atmospheric corrosion. Its typical chemical makeup includes carbon (≤0.15%), manganese (0.25–0.50%), phosphorus (≤0.04%), sulfur (≤0.05%), silicon (0.30–0.65%), copper (0.25–0.55%), chromium (0.40–0.65%), and nickel (≤0.50%). On the mechanical side, it offers a minimum yield strength of 345 MPa and a tensile strength ranging from 485 to 620 MPa, along with excellent toughness and formability. These characteristics make it perfect for structural applications that face the elements, as the steel develops a stable rust-like finish over time, which cuts down on the need for painting or upkeep.
