347 stainless steel wire mesh is similar to the basic 304 stainless steel alloy, but includes the addition of niobium and tantalum. The niobium content allows for the elimination of carbide precipitation / intergranular corrosion, and the corrosion resistance is better than 321. The combination of the chromium and tantalum additions give 347 stainless steel wire cloth excellent creep and stress rupture properties when compared to 304L.

Applications
347 stainless steel wire cloth is principally used in applications where other stainless steel alloys (304L) are susceptible to intergranular corrosion (so the weld and the base metal are equally corrosive resistant). The primary applications are oil field & refinery, mining & quarrying, and aerospace. Additional industries and applications which commonly use 347 stainless steel wire cloth include:
Food Processing
Liquid Filtration & Particle Separation
Pressure Vessels
Steam Piping
Waste Treatment
