Super Duplex Seamless & Welded BW Fittings
Duplex stainless steels are becoming more common. They are being offered by all the major stainless steel mills for a number of reasons:
Higher strength leading to weight saving
Greater corrosion resistance particularly stress corrosion cracking
Better price stability
SAF 2507 ?is a registered trademark for Sandvik
This is a Duplex alloy stainless steel designed to feature high strength, resistance to pitting, stress corrosion cracking, erosion corrosion and corrosion fatigue, crevice corrosion and strong weldability.
