SUS304( L )
| Distinguish |
SUS304 |
SUS304L |
|
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. |
