Trommel Screen Perforated Panel in 304 Stainless Steel (AISI 304 (1.4301)) is used for screening compost, soil, municipal waste, gravel and wood chips in rotating trommel drums lined with heavy perforated steel panels. 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.
