Main material properties and Applications:

Other materials could be available, if need.

200 series:

201,202, etc

Nickel content is 10-14%

Be used in decorating and low price

 

300 series:

301

Properties (extension, welding, pressure resistance, etc) are better than 304 in.

 

304/304L/304H

Nickel content is 8-10%. TP304H is the update material for TP304/304L and more hot-resisting.

Apply to following fields: petroleum, chemical, coal chemical industry, sea engineering, offshore drilling platform, chemical fertilizer industry.

 

316/316l/316H/ss316

Nickel content is 10-14%.

Adding Molybdenum elements makes it better ability to resist chloride corrosion, better effect to the seawater corrosion and more corrosion resistant than 304. SS316 is widely used in the nuclear industry.

Apply to following fields: petroleum, chemical, coal chemical industry, sea engineering, offshore drilling platform, chemical fertilizer industrial

 

321

Adding Ti elements makes it better ability to resist weld-seam corrosion, better effect to tension intensity.

Apply to following fields: petroleum, chemical, coal chemical industry, sea engineering, offshore drilling platform, chemical fertilizer industry.

 

310, 310S

High temperature resistance ability is well, such material can bear 500-600℃.

Nickel content is 19-22%

Higher price

 

Duplex/supper duplex steel pipe

S31803, s32250, s32760, s31500, s32001, ss316, s32304, etc

High mechanical strength and excellent corrosion resistance

Apply to the dangerous environment in which broken accidence is more likely to be resulted by high temperature, pressure and corrosion.

Be widely used in following fields: petroleum, chemical, coal chemical industry, sea engineering, offshore drilling platform, chemical fertilizer industrial, papermaking, machinery, transport vessel, construction, etc.

 

400 series

409, etc

Adding Ti elements makes it better ability to resist weld-seam corrosion, better effect to tension intensity.

Nickel content is 10-14%
