304 Stainless Steel Bar
304 stainless steel, as one of the most commonly used types of stainless steel, is an outstanding material when it comes to corrosion resistance, heat resistance, low temperature strength and mechanical properties. In addition, it has exceptional hot-workability so it leaves no heat treatment hardening phenomenon.

Product Show
304 stainless steel bar is one of the most popular stainless steel bars across the globe for a number of reasons. Iron, chromium and nickel are the main elements that constitute 304 stainless steel. This combination gives rise to the outstanding oxidation resistance and corrosion resistance of 304 stainless steel bars. 304 stainless steel has stronger anti-rust properties than 200 series stainless steel materials as a versatile stainless steel. It also outperforms them in temperature resistance. The 304 stainless steel bar has characteristics of a smooth surface, high plasticity, toughness and mechanical strength, as well as resistance to corrosion by acids, alkaline gases, solutions and other media. 304 stainless steel bars are commonly used as manufacturing parts in fields like food processing equipment, building materials, automobile parts.
Surface Treatment
| Surface finish | Characteristics & Application |
| NO.1 | Hot-rolled surface, annealed and pickled, can be used as cold-rollingmaterial, industrial tanks and chemical devices. |
| NO.2D | Cold-rolled, annealed and pick led with out skin passing the dullproducts can be used as auto mo bile parts, building materials andpiping. |
| NO.2B | The surface brightness and flatness of NO.2B is better than NO.2D.Then through a special surface treatment to improve its chemicalproperties, NO.2B. could nearly satisfy comprehensive uses. |
| NO.3 | Polished with abrasive belt of grit #100#120, have better brightness withdiscontinuous coarse stria, used as inner and external ornaments forbuilding, electrical appliances and kitchen utensils etc. |
| NO.4 | Polished with abrasive belt of grit #150#180, have better brightness withdiscontinuous coarse stria, but thinner than NO.3. are used as bathtubbuilding inner and external ornaments electrical appliances, kitchenutensils and food processing equipment etc. |
| HL | Polished with abrasive belt of grit #150-320 on the No.4.finish and hascontinuous streaks, mainly used as building ornaments, elevators, doorof building, frontal plate etc. |
| BA | Cold-rolled, bright annealed and skin passed, the product has excellentbrightness and good reflexivity like mirror, used for electrical appliances,kitchen apparatus, ornament materials etc. |
