304L Stainless Steel Coil
304L stainless steel coil is a low-carbon variation of the classic 304 austenitic chromium-nickel stainless steel, supplied in continuous coil form. The reduced carbon content (≤0.030%) minimizes carbide precipitation during welding, making it particularly suitable for welded components where post-weld annealing is not feasible. It offers excellent forming characteristics and good overall corrosion resistance.

SURFACE CHARACTERISTIC SUMMARY OF MANUFACTURING METHOD APPLICATION
NO.1 Silvery white Hot rolled to specified thickness Do not need to have a glossy surface use
lackluster
NO.2D Silvery white After cold rolling, heat treatment and pickling are carried out General material, deep material
NO.2B Gloss is stronger than No.2D After No.2D treatment, the final light cold rolling is carried out through the polishing roller The general material
BA As bright as a sixpence No standard, but usually a bright annealed surface with high reflectivity. Building materials, kitchen utensils
NO.3 Rough lapping Grind with 100~200# (unit) strop tape Building materials, kitchen utensils
NO.4 Intermediate grinding Polished surface obtained by grinding with 150~180# strop abrasive tape Building materials, kitchen utensils
NO.240 Fine lapping Grinding with 240# strop abrasive tape kitchenware
NO.320 Very fine grinding Grinding was carried out with 320# strop abrasive tape kitchenware
NO.400 The luster is close to BA Use 400# polishing wheel to grind General timber, building timber, kitchen appliances
HL Hairline grinding Suitable particle material for hair stripe grinding (150~240#) with many grains Building, construction material
NO.7 It's close to mirror grinding Use a 600# rotary polishing wheel to grind For art or decoration
NO.8 Mirror ultrafinish The mirror is ground with a polishing wheel Reflector, for decoration
