Distinguish | 304 | 304L |
The characteristic | --The basic steel of body is planted in, the use is the most extensive; --Corrosion resistance and heat resistance are fine; --The intensity and mechanical performance of low temperature are fine; --It is single-phase organize bodies,have heat treatment phenomenon of hardenning( have magnetic of, Use - 196 temperature --800). | --Possess all SUS 304 characteristics ; --Corrosion resistance and heat resistance are fine ; --After oring dispel the stress after welding, can also keep good corrosion resistance ; --Deeply the washing nature, the polishing quality is fine. |
The use | --Tableware, kitchen, water heater, boiler, bathtub and weldsing and managed; --Automobile fittings, shelf rain of silencer, wind brush and mould goods; --Medicine equipments , construction materials , chemical industries equipments, agricultural utensil, Shiping part and electronic product. | --Apply to chemistry, coal carbon, stone with high corrosivity while resisting brilliantly Apparatus and equipment in the environment of the oil; --Open-air ornament materials, able to bear There is part of the difficulty in hot part and heat treatment. |
