Stainless Steel 440C Bolts have Carbon (0.95–1.20%), Chromium (16–18%), Manganese (up to 1%), Silicon (up to 1%), and minor constituents such as Molybdenum. When heat-treated, these have high tensile strength (up to 760 MPa) and hardness (up to 60 HRC). With a density of 7.75 g/cm³ and a melting point of about 1480–1530°C, 440C bolts possess fine dimensional stability and wear resistance. Even though their corrosion resistance is less than in austenitic grades, it is sufficient to be applied in mildly corrosive situations, and thus they are suitable for precision-critical and high-performance applications.
