Credibility ,Type 347 stainless steel is a stabilized austenitic stainless steel similar to type 304 with an addition of Columbium and Tantalum. The columbium serves to produce a stabilized type of stainless steel which is immune to chromium carbide precipitation. This type of grades are thus recommended for parts fabricated by welding which cannot be susequently annealed or for parts which must operate in service between 800 – 1600°F.

Type 347 stainless steel can be cold rolled various tempers. Contact Ulbrich Technical Services for additional information.
Cold Forming
347 stainless steel can be readily formed and drawn. Like most other austenitic stainless steels, type 347 work hardens and may require annealing after severe forming.
Welding
347 stainless steel is weldable by common fusion and resistance methods. Use type 347 or 348 filler rod or electrodes. For best results refer to: Yaang’s “Welding of Stainless Steels and Other Joining Methods”.
