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:
