Product Show
321 stainless steel has better crack resistance during the welding process due to the titanium content. In addition, 321 stainless steel also has good processing and welding properties, making it easy to perform cutting, bending, welding and other processing operations. Its mechanical properties such as tensile strength, flexural strength and elongation are also excellent, and can meet the requirements of use in various complex environments. Because 321 stainless steel have excellent corrosion resistance and high temperature performance, they are widely used in petroleum, chemical industry, aviation, aerospace and other fields. In the petroleum and chemical industries, since the production process involves a large amount of corrosive media such as acids, alkalis, and salts, 321 stainless steel can effectively resist the corrosion of these media and ensure the long-term stable operation of the equipment. In the aviation and aerospace fields, 321 stainless steel has become one of the important structural materials due to high operating temperatures and the requirement for materials with good creep resistance.
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. |
