Dishwasher Micro Filter in 304 Stainless Steel (AISI 304 (1.4301)) is used for keeping food particles out of the dishwasher wash pump and spray arms with an etched stainless micro filter and coarse cup in the sump. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.
