347 Stainless Steel Wire Mesh – Alloy Overview
Type 347 stainless steel wire mesh is similar to the basic T-304 stainless steel alloy, but includes the addition of niobium (formerly called columbium) and tantalum. The niobium content allows for the elimination of carbide precipitation / intergranular corrosion, and also supports superior corrosion resistance vs. even that of T-321. The combination of the chromium and tantalum additions give T-347 stainless steel wire cloth excellent creep and stress rupture properties when compared to T-304L. T-347 is usually selected over T-321 in many aqueous and other low-temperature environments. Some characteristics of 347 stainless steel wire cloth which dictate its use are:
- Austenitic stainless steel.
- Non-magnetic when annealed.
- Slightly magnetic when cold worked.
- Withstands outdoor exposure without rusting.
- Excellent oxidation & corrosion resistance in broad range of industrial and chemical settings.
- Resists oxidation at 1500°F temperatures.
- Heating permitted between 800°F – 1500°F temperatures.
- Can be cut, formed, and welded.
Industries & Applications
T-347 stainless steel wire cloth is principally used in applications where other stainless steel alloys (i.e. T-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 T-347 stainless steel wire cloth include:
- Food Processing
- Liquid Filtration & Particle Separation
- Pressure Vessels
- Steam Piping
- Waste Treatment
Common Aliases
Type 347 stainless steel is also commonly referred to as:
- T-347
- SS347
- UNS S34700
- SUS347 (Japan)
