Water Pitcher & Dispenser Filter Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for retaining carbon granules and ion-exchange resin inside water pitcher cartridges and protecting dispenser taps from particles. 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.
