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
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.
