SS321 Stainless Steel Filtration Mesh Woven Metal Cloth
SS321 Stainless Steel Woven Filtration Metal Cloth
Description of Woven Filtration Metal Cloth
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.
