You’ll find Stainless Steel 440C bolts in a variety of applications that require high strength, precision, and wear resistance. They’re commonly used in aerospace components, surgical instruments, valves, high-performance bearings, pump parts, and mechanical systems that face high friction. In the industrial realm, they’re favored for tooling fixtures, hydraulic assemblies, and automotive performance parts. Thanks to their exceptional hardness and dimensional stability, they’re also ideal for marine and defense-grade fastening in extreme operating conditions. When durability and wear resistance are your top priorities, 440C bolts are the perfect choice.
Stainless Steel 440C bolts are made with a high carbon content (about 1.0%) and chromium (16–18%), along with small amounts of manganese, molybdenum, and silicon. This unique blend allows 440C to reach impressive hardness levels—up to 58–60 HRC when heat-treated. The alloy boasts a tensile strength of around 760 MPa and a yield strength of about 450 MPa. Its outstanding wear resistance, decent corrosion resistance (when hardened), and high strength make it perfect for high-stress applications. However, it’s worth noting that it’s not as corrosion-resistant as lower-carbon stainless grades like 304 or 316.
