304L SS Precision Cold Rolled Coil 0.1mm 0.2mm 0.3mm Tight Tolerance Instrument Grade
Product Spotlights
Product Description:
This 304L stainless steel precision cold rolled coil is available in ultra-thin gauges of 0.1mm, 0.2mm, and 0.3mm with tight dimensional tolerances for instrument grade applications. The low carbon content prevents sensitization during welding or soldering. Precision rolling ensures exceptional thickness uniformity and surface quality. Typical applications include precision gaskets and seals, electronic shielding components, spring shims, diaphragm parts, instrument components, medical device parts, pressure switch components, nameplate stock, fuel cell components, and any high-precision application requiring ultra-thin, tight tolerance stainless steel.
