Stainless Steel 440B Stud Bolts are made from martensitic stainless steel, typically containing carbon (0.75–0.95%), chromium (16–18%), along with manganese, silicon, phosphorus, and sulfur. The high carbon content allows for exceptional hardness after heat treatment. These bolts boast impressive tensile strength, yield strength, and wear resistance, making them perfect for high-stress applications. While 440B provides moderate corrosion resistance, this can be improved with proper tempering. Their mechanical properties include high hardness values (up to 58 HRC) and strong abrasion resistance, making them ideal for heavy-duty fastening tasks.
