321 Stainless Steel Wire Mesh

321 Stainless Steel Wire Mesh – Alloy Overview

Type 321 stainless steel wire mesh is similar to the basic T-304 stainless steel alloy, but includes the addition of titanium for improved oxidation and general corrosion resistance. Compared to T-304L, T-321 stainless steel has both higher creep strength and stress rupture capabilities, and similarly possesses good low-temperature toughness. That said, T-304L wire mesh is usually more readily available than T-321, and is often used in most situations unless the wire mesh is to be used in an operating environment with temperatures above 925°F (as T-321 has better hot strength properties).  If the requirement is only for resistance to intergranular corrosion after welding, then T-304L is the preferred alloy given its wider stock availability. Some characteristics of 321 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 900°F – 1600°F temperatures.
  • Can be cut, formed, and welded.

Industries & Applications

T-321 stainless steel wire cloth is principally used in oil field & refinery, mining & quarrying, and aerospace industries.  T-321 wire cloth is also commonly used in the chemical processing industry. Additional industries and applications which commonly use T-321 stainless steel wire cloth include:

347 Stainless Steel Wire Mesh

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:
