Harsh Metalloys, based in Mumbai, India, is a trusted manufacturer and supplier of Stainless Steel 440B Stud Bolts, celebrated for their impressive hardness, wear resistance, and dependable performance even under high mechanical stress. Grade 440B is a high-carbon martensitic stainless steel that provides enhanced strength and heat-treatable hardness compared to many standard stainless grades. Our 440B stud bolts are meticulously engineered to comply with international standards like ASTM and ASME, making them perfect for applications where both structural integrity and moderate corrosion resistance are crucial. These bolts find extensive use in mechanical, automotive, aerospace, and industrial assembly operations.
Stainless Steel 440B Stud Bolts are made up of about 16–18% Chromium and 0.75–0.95% Carbon, along with small amounts of Manganese and Silicon. This unique composition allows the alloy to be heat-treated, achieving Rockwell hardness values exceeding 55 HRC. These stud bolts boast high tensile strength (usually above 720 MPa) and remarkable resistance to wear and deformation. While their corrosion resistance is moderate compared to austenitic grades, they excel in dry or mildly corrosive environments. Their dimensional stability and strength make them perfect for fastening under tension in critical applications.
