These sheets and plates are primarily made up of iron, chromium (15–17.5%), nickel (3–5%), and copper (3–5%), with trace amounts of niobium and tantalum. This unique composition enables precipitation hardening via heat treatment, leading to high tensile strength (up to 1100 MPa) and excellent hardness. On a mechanical level, the alloy offers good ductility, toughness, and resistance to fatigue, oxidation, and corrosion in both fresh and marine environments.
