Filter rating range of the SS filter cartridges is determined by the corresponding filter media.
Typical ratings are 0.5 1 2 5 10 15 20 25 30 40 50 100 150 20 microns.
SS 304, 304L, 316 and 316L are the mostly used material for stainless cartridges.
While 310S (for high temperature), 904L (for high corrosion resistant) and Duplex 2205 / 2507 (higher strength and corrosion resistance) stainless steel are also applied in some demanding applications.
Other metal materials ( titanium, nickel based alloy, copper alloy, etc) can also be used for filter cartridges if stainless steel is still not satisfactory.
