Duplex 2507 round bar has good mechanical properties. The same design strength as thicker nickel alloys can often be achieved using lightweight alloy 2507 bar.
Higher chromium, molybdenum and nitrogen contents result in a Pitting Resistance Equivalent Number (PREN) >40, providing superior pitting and crevice corrosion resistance to austenitic and duplex stainless steels in almost all corrosive media. It also provides higher strength than austenitic and 22% Cr duplex stainless steels.
