Rotary Shaver Head Guard Cap in 304 Stainless Steel (AISI 304 (1.4301)) is used for forming the slotted guard of rotary shaver heads, which lifts and guides hairs into the spinning cutter beneath. 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.
