304 |
The stainless steel has the widely use, good anti-corrosion, heat-resisting,low-temperature strength and machine characteristics;it can be punched and bend well when it is hot working, and its hardering will not to be happened.(non-magnetism, the temperature between -196℃ to 800℃). | Household appliances(type 1, 2 are tableware, cupboard, indoor pipelining, heater, boiler, bathtub),the parts for car(windshield wiper, filtering, moldering), medical appliances, building materials, chemistry, food industry, agriculture, ship parts. |
|
Automatic lathe |
303 |
It will be good free-cutting to add S in the base of 304 . | Use to the parts which has high quality free-cutting, such as the parts for electronics. |
|
303CU |
It will be shapped well to add S in the base of 303. | Use to the parts which has high quality free-cutting, such as the parts for electronics. | |
|
Bearing and automatic lathe |
303 |
It will be good free cutting to add S in the base of 304 . | The bearing for OA furniture/for civil and the shaft for driving and puddler/for high quality pump. |
|
304 |
The stainless steel has the widely use, good anti-corrosion, heat-resisting,low-temperature strength and machine characteristics;it can be punched and bend well when it is hot working, and its hardening will not to be happened by heat-treatment.(non-magnetism, the temperature between -196℃ to 800℃). | ||
|
416 |
Free cutting will have a good comprehensive performance to add S by heat-treatment. | ||
|
Forging,machine work |
304L |
The low C for the grade of 304, on the common condition, its anti-corrosion is same as Type 304, but its capacity of anti-corrosion in the crystal is excellent afterwards weld or dispel stress. it will keep anti-corrosion when it has not heat-resistanted, the temperature between -196℃ to 800℃. | Apply for field machines in chemisty,coal industry,oil industry which must be high quanlity anti-corrosion in crystal,for heat-resistanted parts in building and for the parts which difficult to heat-resisting. |
|
316 |
If add Mo in it, its anti-corrosion, anti-corrsion by air and hyperthermia strength are specially good, it can be used in a cruel environment and its hardness will be improved by cold finish (non-magnetism). | For equipments which in the sea, chemistry, dye processing, papermaking,oxalic acid, fertilizer, photography, food industry, the facilities of coastal regions, for rope, CD pole, bolt, nut. | |
|
Driving shaftdriving shaft |
304N |
Compared with 304, it is added N for high strength which use in the structure parts. | The shaft for the pump and ship. |
|
316N |
For high strength which use in structure parts. | ||
|
Chemical oil and pressure vessel. |
316L |
The low-C series for the grade of 316 ,its anti-corrosion in crystal is excellent, besides the characteristics of the grade 316. | Use in the grade of 316 which has special requirment in anti-corrosion in crystal. |
|
Aviation and boiler |
321 |
Add the element Ti into the grade of 304 to avoid corrosion in the crystal,its temperature between 430℃ to 900℃. | Aircraft, exhaust guide, boiller. |
|
The bearing and the structure parts. |
630 (17-4) |
Maraging stainless steel, high strength and anti-lashed; it will get varied characterstics of the strength by the different heat treatment's way. | High strength bearing and the structure parts. |
|
XM-19 |
Austenite stainless steel includes N and microelement. |
