Type 347 is similar to Type 321 Stainless steel but the only differene is slightly improved corrosion resistance in strongly oxidizing environments. It contains columbium and is widely used in high temperature environments. 347 stainless steel has amazing features such as good welding and forming capabilities. It is also known as UNS S32109 that provide higher temperature strength. Stainless Steel 347 is essentially non-magnetic in the annealed condition and can only be hardened by cold working.
