Product Details

321 stainless steel wire mesh/screen is a titanium-stabilised version of Grade 304 wire mesh/screen, used in particular applications within the sensitizing temperature range. 321 stainless steel wire mesh's resistance to sensitization, coupled with its higher strength at high temperature makes it suitable in application where Grade 304 will become sensitized, or where Grade 304L has insufficient hot strength. It is not subject to weld decay (intergranular corrosion) when exposed to mildly corrosive environments. However, welded Grade 321 must never be used in highly oxidizing environments as it is liable to 'Knife-line' attack.

321 Stainless Steel Typical Applications

321 stainless steel is used almost exclusively for service within the sensitizing temperature range (450-850^oC). In welded ambient temperature applications it has been replaced by Grade 304L. Some typical areas of application are: Furnace components, super-heater and afterburner parts, compensators and expansion bellows.
