Kitchen Sink & Drain Strainer Basket in 304 Stainless Steel (AISI 304 (1.4301)) is used for catching food scraps at the kitchen sink outlet while letting water drain freely. 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.
