Based in Chennai, India, Vinit Stainless is a reputable manufacturer and supplier of SMO 254 Pipe Fittings. Vinit Stainless, a specialist in high-performance alloy fittings, provides precisely engineered SMO 254 products made for highly stressful and corrosive conditions. SMO 254 fittings are perfect for the offshore, chemical, and marine industries because of their outstanding strength and remarkable resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Vinit Stainless guarantees that every product satisfies international standards by emphasising quality, customisation, and global compliance. The company is dedicated to offering industries in India and around the world dependable solutions with prompt delivery and first-rate customer support.
The high-alloy austenitic stainless steel used to make SMO 254 Pipe Fittings has about 20% chromium, 18% nickel, 6% molybdenum, and ~0.2% nitrogen added for strength and corrosion resistance. SMO 254 has exceptional resistance to corrosion caused by chloride because of its composition. The material has outstanding ductility and impact strength, with a tensile strength of roughly 650 MPa and a yield strength of roughly 300 MPa. These fittings are particularly well-suited for applications involving seawater, brine, and harsh chemical processing because they retain their mechanical integrity under extreme pressure and temperature.
