| 304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm3, which is also called 18/8 stainless steel in the industry. |
| High temperature resistant to 800°C and processability. Common labeling methods on the market include 0Cr18Ni9 and SUS304. Among them, 0Cr18Ni9 generally means national standard production, and 304 generally means ASTM standard production. |

Production details
| 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 |
| 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 |
