Product Show
321 stainless steel pipe has good processing and welding properties, making cutting, bending, welding and other processing operations easy to perform. Besides, it has superior mechanical properties such as tensile strength, flexural strength and elongation, and can meet the requirements of use in various environments. Because 321 stainless steel pipes have excellent corrosion resistance and high temperature performance, they are commonly seen in petroleum, chemical industry, aviation, aerospace. Since the production process of petroleum and chemical industries involves a large amount of corrosive media such as acids, alkalis, and salts, 321 stainless steel pipes can effectively cope with the corrosion of these media and ensure the stable operation of the equipment. 321 stainless steel pipe has become one of the important structural materials in the aviation and aerospace fields.
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. |
