Stainless Steel Super Duplex 2507 is designed for applications which demand exceptional strength and corrosion resistance. The high molybdenum, chromium and nitrogen content in Super Duplex 2507 results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides Super Duplex 2507 with exceptional resistance to chloride stress corrosion cracking. Usage of Super Duplex Steel 2507 should be limited to applications below 600° F (316° C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of Alloy 2507.
