Smart Speaker Wrap-Around Metal Grille in 304 Stainless Steel (AISI 304 (1.4301)) is used for wrapping cylindrical and oval smart speakers in a seamless micro-perforated metal shell that radiates sound in all directions. 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.
