304 Polished Stainless Steel Sheet

304/304L polished stainless sheet coil and sheet is part of the austenitic family of stainless steel. 304 grades contain a lower level of carbon than 302 and 304/304L has a lower carbon level than straight grade 304. Types 304 and 304L have very good drawability and excellent corrosion resistance in chemical, textile, petroleum and food industry exposure.  No. 4 polished surface is a non-reflective brushed finish obtained by course grinding followed by finishing with a 120-150 mesh abrasive. This general purpose bright finish has a visible grain to prevent mirror reflection.  Polished surfaces are easy to clean, ensuring a minimum foothold for dirt, bacteria and corrosive substances.

TW stocks a wide range of sizes in 304/304L stainless certified to AMS 5511, ASTM A 240, and ASTM A 666.
