ABout UNS N08700 / Alloy 700
UNS N08700 is a high-alloy, fully austenitic, superaustenitic stainless steel. This alloy is a proven problem-solver in many applications where corrosive conditions are too severe for standard grades of stainless steel. It has also provided a cost-effective alternative to more expensive nickel-base and titanium-base alloys.
UNS N08700 stainless steel is more highly alloyed than standard stainless steels. The high molybdenum content is particularly important to the corrosion resistant properties. It enhances development of the passive film responsible for the corrosion resistance of stainless, and makes the alloy more noble so that corrosion resistance is improved even under conditions which tend to destroy passivity.
The chromium content of the N08700 is essential to corrosion resistance. Since chromium contributes to sigma formation, the 20% level was chosen as a satisfactory compromise. The high nickel content not only minimizes sigma, but also contributes markedly to corrosion resistance. The effects of higher nickel are believed to relate more to corrosion propagation than to initiation. The combination of the three major alloying elements gives N08700 stainless steel a high degree of resistance to stress corrosion cracking. No field service failures from stress corrosion cracking in N08700 Alloy have been reported to date.
