2507 super duplex machinability is poor. In order to improve the poor machinability of 2507 super duplex, high content of ferrite (above 60%) is used. The pitiable machinability is generally caused due to elevated tensile strength and yield strength. 2507 super duplex can tolerate organic and inorganic acids and it has a high resistance to general corrosion, chloride pitting and stress.

steel SAF 2507™, which has a PRE (Pitting Resis-tance Equivalent) value of 42.5 due to its chemical composi-tion of 25% Cr, 4% Mo and 0.3% N compared to other steels (see Table 1). SAF 2507 is specially designed for highly corrosive conditions and chloride-bearing environments. Its high

Super Duplex 2507®, is very similar to UNS S31803 2205® Duplex. The difference between the two is the contents of chromium and nitrogen are higher in the 2507® which in turn creates higher corrosion resistance as well as a longer lifespan. 2507® is composed of between 24% to 26% chromium, 6% to 8% nickel, 3% molybdenum, and 1.2% manganese
