Brewery Lauter Tun False Bottom in 304 Stainless Steel (AISI 304 (1.4301)) is used for separating sweet wort from the grain bed in brewery lauter tuns and mash filters with wedge wire false-bottom plates. 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.
