Filter Bag Support Basket in 304 Stainless Steel (AISI 304 (1.4301)) is used for supporting liquid filter bags inside bag filter housings with perforated stainless baskets that keep the bag from bursting under pressure. 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.
