Product Show
310S stainless steel bar has great performances in terms of oxidation resistance, corrosion resistance, acid and alkali resistance given its high content of nickel and chromium. After increasing the content of carbon in austenitic stainless steel, the strength is improved because of its solid solution strengthening effect. The chemical composition of austenitic stainless steel mainly features chromium and nickel, with extra molybdenum, tungsten, niobium and titanium. With a face-centered cubic structure, it has better strength and creep strength at high temperatures. 310S stainless steel bars are commonly adopted as manufacturing parts in the production of boiler, steam turbine, industrial furnace and aviation, petrochemical.
Surface Treatment
| Surface finish | Characteristics & Application |
| NO.1 | Hot-rolled surface, annealed and pickled, can be used as cold-rolling material, industrial tanks and chemical devices. |
| NO.2D | Cold-rolled, annealed and pick led with out skin passing the dull products can be used as auto mo bile parts, building materials and piping. |
| NO.2B | The surface brightness and flatness of NO.2B is better than NO.2D. Then through a special surface treatment to improve its chemical properties, NO.2B. could nearly satisfy comprehensive uses. |
| NO.3 | Polished with abrasive belt of grit #100#120, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc. |
| NO.4 | Polished with abrasive belt of grit #150#180, have better brightness with discontinuous coarse stria, but thinner than NO.3. are used as bathtub building inner and external ornaments electrical appliances, kitchen utensils and food processing equipment etc. |
| HL | Polished with abrasive belt of grit #150-320 on the No.4.finish and has continuous streaks, mainly used as building ornaments, elevators, door of building, frontal plate etc. |
| BA | Cold-rolled, bright annealed and skin passed, the product has excellent brightness and good reflexivity like mirror, used for electrical appliances, kitchen apparatus, ornament materials etc. |
