• Introduction
  • Duplex 2507 is a super duplex  stainless steel designed for applications which demand exceptional strength  and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7%  nickel. This high molybdenum, chromium and nitrogen content results in excellent  resistance to chloride pitting and crevice corrosion attack and the duplex  structure provides 2507 with exceptional resistance to chloride stress  corrosion cracking.
  • Usage of Duplex 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.
  • Duplex 2507 possesses excellent  mechanical properties. Often a light gauge of 2507 material can be used to  achieve the same design strength of a thicker nickel alloy. The resulting  savings in weight can dramatically reduce the overall cost of fabrication.
