The Fasteners Mart, Mumbai, India, is a well-known industrial fastener supplier that is recognized for reliability, quality, and precision-engineered solutions. We supply products to a broad array of industries such as automotive, aerospace, oil & gas, and construction with products designed to endure harsh conditions. One of our high-performance products is Stainless Steel 440B Stud Bolts. Made of Grade 440B stainless steel, these round-threaded fasteners provide high hardness, strength, and mild corrosion resistance—perfect for demanding, high-load situations in challenging or high-temperature conditions.
440B Stainless Steel Stud Bolts are made up of carbon (0.75–0.95%), chromium (16–18%), and trace elements such as manganese, silicon, and molybdenum. They provide a maximum tensile strength of 760 MPa and can reach a Rockwell hardness of about 58 HRC through heat treatment. The density is about 7.8 g/cm³ and they have a melting range between 1480–1530°C. All this makes them extremely suitable for high-wear applications that need both strength and moderate corrosion resistance.
