Chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), nitrogen, and an iron balance make up the majority of the composition of Duplex Steel Coil/Slitting Coil. The alloy offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking by combining the advantageous qualities of ferritic and austenitic stainless steels. Duplex steel’s mechanical properties include a tensile strength of 620–800 MPa, a yield strength of about 450 MPa, and an elongation of about 25%. It is perfect for demanding industrial applications because of its dual-phase microstructure, which guarantees increased toughness and strength even in harsh environments.
