Stainless Steel 422 Bolts are martensitic stainless steel bolts with a primary composition of iron, chromium (12–14%), molybdenum (0.5–1%), tungsten, and carbon (0.20–0.30%), providing superior heat resistance and corrosion protection. They have high tensile strength (as much as 140 ksi), yield strength of about 100 ksi, and excellent toughness. These bolts have a mechanical stability at high temperature up to 1200°F (649°C). Their hardness and oxidation resistance are better, and they are best suited for stress-critical applications. Under severe operating conditions, their mechanical properties and wear resistance are also improved by proper heat treatment.
