Stainless steel SS 347 is columbium (niobium)-strengthened austenitic steel with higher intergranular corrosion resistance. SS 347 is formulated to be partly resistant to service at high temperatures and to be satisfactory for service in those applications that place the material in aggressive environments, including welding or thermal cycling.

Stainless Steel SS 347 is an austenitic high-alloy steel appropriate especially for the most severe conditions in high temperature processes and applications such as welding. The addition of columbium (niobium) offers the best intergranular corrosion resistance, especially after welding, and is appropriate for applications where otherwise precipitation of the carbides can weaken the material's strength
