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%
