Stainless steel strip is a thin steel plate supplied in coils, also called strip steel. There are imported and domestic products, divided into hot-rolled and cold-rolled. According to the needs of different users, we can also order a variety of special-shaped steel materials.In order to ensure that the yield strength, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo heat treatment such as annealing, solution treatment, and aging treatment before delivery.
The stainless steel coil has a smooth surface, high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. It is an alloy steel that is not easy to rust, but it is not absolutely rust-free. Stainless steel coil refers to steel coil resistant to corrosion by weak media such as atmosphere,steam and water, while acid-resistant steel coil refers to steel coil resistant to corrosion by chemically corrosive media such as acid, alkali and salt.
| 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 |
| 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 |
| NO.8 | 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 |
