410 Stainless Steel Composition & Martensitic Properties

410 (UNS S41000) is a martensitic stainless steel containing 11.5–13.5% chromium with very low nickel content. It is heat‑treatable and capable of achieving high strength and hardness through quenching and tempering. As a classic martensitic stainless steel, 410 offers moderate corrosion resistance and excellent mechanical performance.
resistance and excellent mechanical performance. It is widely used for valve components, pump shafts, knives, fasteners, wear‑resistant parts, and mechanical structures. Weldability is limited, and post‑weld tempering is recommended to prevent cracking.

410 is supplied as plates, bars, tubes, and forgings. It is a cost‑effective material for applications requiring strength, hardness, and moderate corrosion resistance.
