Stainless Steel 420 Tubing is a martensitic stainless steel alloy containing approximately 12–14% chromium and high carbon content (0.15–0.40%). The high carbon allows for heat treatment, achieving high hardness and tensile strength. The tubing typically exhibits tensile strength between 600–900 MPa and hardness up to 50 HRC after proper heat treatment. Its martensitic structure provides excellent wear resistance, edge retention, and mechanical strength, making it suitable for industrial, tooling, and wear-intensive applications.
