Car Door Speaker Grille in 304 Stainless Steel (AISI 304 (1.4301)) is used for covering door-mounted car audio woofers and midrange speakers with a domed, perforated metal grille that protects the cone from knees, bags and cargo. 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.
