Special Materials
Super Duplex Fittings
Super Duplex fittings in SAF 2507 (S32750) and S32760 combine the high strength of ferritic steels with the corrosion resistance of austenitic grades, offering roughly double the yield strength of 316L with superior resistance to chloride stress corrosion cracking. Shree Raj Steels supplies super duplex fittings for offshore, subsea, and aggressive chemical environments.
