These coils are typically crafted from stainless steel alloys like grades 304, 316, 430, or similar, featuring high chromium content for corrosion resistance and nickel for added toughness. In a half-hard temper, they strike a balance with moderate yield strength and good formability; while in a hard temper, they offer higher strength, reduced ductility, and increased rigidity. The tensile strength usually falls between 550-750 MPa for full hard, with yield strength being appropriately lower; half-hard coils typically range from 350-550 MPa. The surface finish is smooth and free from scale, achieved through cold-rolling or annealing, depending on the temper.
