About 347 Stainless Steels

347 stainless steel is a columbium/tantalum stabilized austenitic chromium-nickel stainless steel. UNS S34700, commonly known as SS 347 is advantageous for high temperature service because of its good mechanical properties . SS 347 also has excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800° to 1500° F. SS 347 is similar to SS 321 with respect to intergranular corrosion which is achieved through the use of columbium as a stabilizing element to maximize this feature. SS 347 can not be hardened through heat treating, but elevated properties may be obtained through cold reduction.
