ATI 2003®
ATI 2003® (UNS S32003) lean duplex stainless steel (LDSS) is a molybdenum-enhance, proprietary* duplex stainless steel alloy. Cr, Ni, Mo, and N are controlled to give a phase balance similar to that of ATI 2205™ duplex stainless steel, while reducing costs.
The alloy fills a gap between Type 316 and the ATI 2205™ alloy in terms of corrosion resistance, while processing the higher mechanical properties characteristic of a duplex stainless steel. ATI 2003® LDSS can be an economic alternative to Type 316L stainless steel, providing enhanced strength and corrosion resistance.
