Alloy 410 is the basic, general purpose martensitic stainless steel that is used for highly stressed parts and provides good corrosion resistance plus high strength and hardness. Alloy 410 contains a minimum of 11.5% chromium which is just sufficient enough to demonstrate corrosion resistance properties in mild atmospheres, steam, and many mild chemical environments. It is a general purpose grade that is often supplied in the hardened but still machineable condition for applications where high strength and moderate heat and corrosion resistance are required. Alloy 410 displays maximum corrosion resistance when it’s been hardened, tempered, and then polished.

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.
