904L Stainless steel consists of Chromium, Nickel, Molybdenum and Copper contents, these elements make 904L stainless steel excellent properties to resist corrosion in dilute sulfuric acid, because of the addition of Copper, 904L commonly is used in high pressure and corrosion environment where 316L and 317L perform poorly.
HT PIPE supplys the high quality
904L stainless steel pipes, equivalent grades are DIN 1.4539 and UNS N08904. All pipes are subjected to extensive tests like a hydraulic test, to make sure that there is no leakage and each pipe passes through a prescribed quality control process in order to make sure the best quality.
904L Stainless Steel Pipe(Tube) Standards
ASTM A 312 – seamless, welded, and heavily cold worked austenitic stainless steel pipes
ASTM A 213 – seamless ferritic and austenitic alloy-steel boiler, super heater, and heat-exchanger tubes
ASTM A 269 – seamless and welded austenitic stainless steel tubing for general service
ASTM B 677 – uns n08904, uns n08925, and uns n08926 seamless pipe and tube
Seamless tube is extruded and drawn from a billet while welded tube is produced from a strip that is roll formed and welded to produce a tube.
Welded tube is considerably less expensive than seamless tube and is readily available in long continuous lengths.
Electric Resistance Welded (ERW) pipe is manufactured by cold forming a flat steel strip into a rounded tube and passing it through a series of forming rollers to obtain a longitudinal seam.
The two edges are then simultaneously heated with a high frequency current and squeezed together to form a bond.
