Introduction to 431 Stainless Steel Fasteners

SS Fasteners 431 is a martensitic and heat-treatable stainless steel with good corrosion resistance, high tensile strength, torque strength, and toughness. Its high yield strength prevents cold-working, but it is suitable for deep drawing, cold heading, and spinning. Fabrication involves tempering treatment and hardening, though it has poor weldability. While its corrosion resistance is lower than austenitic grades, and it loses strength at high temperatures and ductility at low temperatures, SS 431 is a reliable choice for applications needing high strength and toughness.
