Weston Stainless, a UK-based company, is a renowned provider of top–grade stainless steel products that deliver long-lasting and corrosion-resistant solutions to industries. One of its high-end products, Stainless Steel 440C Stud Bolts, is a high-carbon martensitic stainless steel bolt with high hardness, strength, and wear resistance. Produced from Grade 440C stainless steel, these stud bolts are offered in numerous shapes such as fully threaded, double-end, and tap-end designs, to provide diversified uses. Having high chromium content, Stainless Steel 440C Stud Bolts ensure excellent mechanical stability, corrosion resistance, and long-term performance, which make them suitable for demanding industrial conditions.
Stainless Steel 440C Stud Bolts consist of iron, chromium (16.0-18.0%), carbon (0.95-1.20%), manganese (1.0% max), silicon (1.0% max), and molybdenum (0.75% max) with this combination of elements providing their strength as well as corrosion resistance. These bolts have a tensile strength of around 760-895 MPa, yield strength of around 450 MPa, and elongation of around 14%. With a density of 7.8 g/cm³ and a melting point of around 1480°C, they possess good thermal conductivity and wear resistance. Their hardness is between 58-60 HRC after heat treatment, which provides exceptional mechanical performance in high-stress conditions demanding higher strength and durability.
