Stainless Steel 431 is a martensitic stainless steel that contains about 15–17% chromium, 1–2% nickel, along with trace amounts of carbon, manganese, and silicon to boost hardness and strength. Mechanically, it boasts impressive tensile strength, high yield strength, and notable hardness after heat treatment. This alloy also offers good fatigue and wear resistance while maintaining its corrosion resistance in moderately aggressive environments. Its unique combination of toughness, hardness, and mechanical stability ensures long-term reliability, making it an excellent choice for components that face mechanical stress and precision engineering tasks.
