Car Tweeter & Dash Speaker Grille in 304 Stainless Steel (AISI 304 (1.4301)) is used for protecting tweeters and dashboard or A-pillar speakers with small, fine-perforated grilles that match interior trim. 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.
