440B Stainless Steel Bolts consist of Carbon (0.75–0.95%), Chromium (16–18%), Manganese and Silicon (≤1%), and Iron as the base metal. These bolts provide high tensile strength, superior wear resistance, and have a hardness ranging up to 58 HRC when heat treated. They also possess a density of around 7.75 g/cm³ and a range of melting from 1480–1530°C. Even though corrosion resistance is intermediate to austenitic grades, they are superior in mechanical strength and dimensional stability. These properties make them the best for load-carrying and wear-critical industrial applications.
