UNS S32750 2507 Duplex

Synopsis

UNS S32750 or 2507 Duplex is a super austenitic premium stainless that is similar to 2205 Duplex. 2507 Stainless Steel is composed of 25% Chrome and 7% nickel which causes the alloy to have an even higher corrosion resistance and longer life span. Along with it being corrosion resistant, UNS S32750 has a high resistance of cracking and pitting, and the yield and tensile strength make it comparable to nickel alloys.


Resistance

Large chromium levels as well as molybdenum content of 2507 Duplex makes this material very resistant to corrosive acidic elements. It implements great resistance to chloride SCC and is preferable to 2205 Duplex in both strength and corrosive resistance.


Processing

2507 Duplex material will be heat treated at climates ~2000°F. After heated, the substance will be pursued by a annealed solution at ~1900°F then submergence in water. 2507 is easily cold worked and has a greater strength/lower ductility than austenitic stainless grades.
