Cold Brew Coffee Filter Cartridge in 316L Stainless Steel (AISI 316L (1.4404)) is used for steeping coarse coffee grounds in cold water for 12–24 hours inside a removable fine-mesh cylinder. The alloy gives superior resistance, including chlorides, brines, food CIP and mild acids and is essentially non-magnetic, with a practical service limit of approx. +550 °C continuous.
