Grade 410 stainless steel is a hardenable, martensitic stainless steel that features a minimum addition of 11.5% chromium. This addition of chromium provides a significant increase in corrosion resistance in mildly corrosive environments where high strength and moderate heat resistance are required. It adequately resists sulfuric acid, nitric acid, and weak acetic acid. Alloy 410 (AMS 5504) is magnetic in both the annealed and hardened conditions.

Type 410 stainless steel displays high strength, heat resistance, and good ductility, making it ideal for the manufacturing of products like bolts, nuts, springs and fasteners, as it can be machined after tempering or annealing. This grade is also commonly used in manufacturing of durable cutlery and kitchen utensils, where its properties allow it to resist the acidity of food products and general corrosion.

While 410 stainless steel materials can readily be welded, it is limited by its hardenability, and it should be pre-heated to reduce the risk of cracking. Post weld heat treatment is not necessarily needed, but recommended to retain required properties, and should be air cooled after annealing.
