347 Stainless Steel Wire Mesh

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)
