304 316 SS Sheet Metal Slit Edge 2B Finish BA No.4 Surface Mill Edge
China Foshan factory 304 stainless steel sheet with 2B/BA/No.4 surface
What is Stainless Steel ?
Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.
2B Finished by heat treatment , picking or equipvalent cold rolling , followed by skin pass to obtain adequate luster surface.
What is BA ?
BA surface finished is Bright heat treatment after cold rolling.
What is NO.4 ?
| Surface Finish | Definition | Application | |
| 2B | Finished by heat treatment , picking or equipvalent cold rolling , followed by skin pass to obtain adequate luster surface. | With bright and smooth surface ,easy for further grinding to obtain brighter surface ,suitable for medical instruments ,milk containers ,tableware and so on. | |
| BA | Bright heat treatment after cold rolling. | Structual members .etc.kitchen utensil ,cutlery ,eleltric applicances ,medical instruments ,building decorations ,etc. | |
| NO.3/NO.4 | Polished with No.150-240 abrasives. | Milky food processing equipment , medicalinstruments ,building decorations. | |
| HL | Finshed by polishing with abrasives of suitable grain size to obtain continuous streaks. | Building decorations ,such as elevators ,escalators ,door etc. | |
| 6K/8K | A mirror-like reflective surface ,which is obtained by polishing with successively finer abrasives and buffing extensively with all gritlines are removed. | Buliding entrances,bulkding column casting ,elevator's wall doors ,counters,sculptures etc. | |
