2020-8-22 · When cold drawn, stainless steel may reach tensile properties of 2,000 MPa or greater, but such high strength levels are usually limited to fine wire sizes. Size is a concern due in part to the quick work hardening rate of stainless steel, which yields diminishing tensile strengthening at the core of a wire as its diameter increases.
