2507 Benefits and Comparisons

Rolled Alloys has an extensive inventory of 2507 items which include Plate, Sheet, Bar, Pipe, Fittings and Welding products. 2507 is a super duplex stainless steel, designed for applications which require exceptional strength and corrosion resistance. This super alloy is made with 25% chromium, 4% molybdenum, and 7% nickel alloy resulting in excellent resistance to chloride pitting and crevice corrosion attack.

This super duplex has great mechanical properties that make it excellent for servicing severe corrosive environments, such as offshore and marine applications.


  • High resistance to chloride stress corrosion cracking
  • Strong resistance to chloride pitting and crevice corrosion
  • High strength
  • Strong general corrosion resistance
  • Suggested for applications up to 600° F
  • Good weldability / workability
  • Resistant to pitting and crevice corrosion in seawater

Due to the beneficial qualities listed above, 2507 is an alloy that is used in a wide range of industrial applications.

How does 2507 compare to other Duplex alloys?
