Motorcycle & ATV Spark Arrester Screen in 304 Stainless Steel (AISI 304 (1.4301)) is used for trapping glowing carbon particles inside motorcycle, ATV and dirt-bike silencers so they cannot ignite dry vegetation. 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.
