Applications:
321 stainless steel pipe seamless steel pipe (GB3087-1999) is used
in the manufacture of various structural low intermediate pressure
boiler superheated steam pipe, water pipe and locomotive boiler
superheated steam pipe, pipes, small pipe and arch brick works of
high quality carbon structural steel hot rolling and cold drawing
(rolling) seamless steel tube.
321 stainless steel pipe: mainly used in the manufacture of high
pressure and over pressure steam boiler pipes, etc. With high
quality carbon structural steel, alloy steel and stainless heat
resistant steel seamless steel tube, the boiler tube by the party
under high temperature and high pressure pipe and works in high
temperature flue gas and steam will happen under the action of
oxidation and corrosion, so the steel pipe with high rupture
strength, high oxidation resistance, and have good organizational
stability, hydraulic prop.
