Vehicle Front Grille & Intake Mesh in 304 Stainless Steel (AISI 304 (1.4301)) is used for filling front grilles and bumper intakes with expanded or woven metal mesh that protects radiators from stones while giving a sporty, open look. 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.
