Gas Appliance Burner & Flame Arrestor Mesh in 304 Stainless Steel (AISI 304 (1.4301)) is used for forming the flame surface of premix gas burners and the flashback screens inside gas appliances. 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.
