Harsh Metalloys stands out as a top manufacturer and supplier of SMO 254 Stud Bolts, proudly based in Mumbai, India. These stud bolts are crafted from high-alloy austenitic stainless steel SMO 254 (UNS S31254), specifically designed to excel in extreme conditions where corrosion resistance is a must. Renowned for their exceptional resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, SMO 254 Stud Bolts are perfect for tough applications. Harsh Metalloys provides precision-engineered fastening solutions that adhere to international quality standards, making these stud bolts ideal for marine, chemical processing, offshore, and desalination industries.
SMO 254 Stud Bolts are constructed from a high-performance alloy that includes around 20% chromium, 18% nickel, 6% molybdenum, and nitrogen, all of which enhance strength and corrosion resistance. This alloy boasts a tensile strength of at least 650 MPa, a yield strength of at least 300 MPa, and an elongation of at least 35%, ensuring a strong mechanical profile even in chloride-rich or acidic environments. The low carbon content of the material improves its weldability and resistance to intergranular attack. These characteristics guarantee that SMO 254 Stud Bolts perform reliably under high pressure and temperature conditions while effectively resisting corrosion in aggressive media.
