303 Stainless Steel Wire Mesh/Screen
303 stainless Steel Wire Mesh/Screen shows good corrosion and oxidization resistance in mildly corrosive atmospheric environments. Its sulphide inclusions act as pit initiation sites meaning it provides a lot less resistance than 304.
Grade 303 stainless Steel Wire Mesh/Screen should not be exposed to marine or other similar environments, to prevent rapid pitting corrosion.
EN 1.4305 303 stainless steel provides good oxidization resistance in intermittent service to 760°C (1400°F) and continuous service to 870°C (1,598°F) The use of 303 stainless steel wire mesh is not recommended in the range of 425-860°C (797-1580°F) due to carbide precipitation. 303 are susceptible to sensitization.
Grade 303 stainless steel is the most readily machineable of all the austenitic grades of stainless steel.
The machineable nature of Grade 303 stainless steel is due to the presence of Sulphur in the steels composition. Whilst the Sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. The corrosion resistance of grade 303 stainless steel is lower than that for 304. The toughness is still excellent as with other austenitic grades.
