It is extremely resistant towards corrosion by warm sea water. It also combats stress corrosion crackling due to the presence of chloride ions. That is primarily because of the high amount of nickel present in it. Copper combats corrosion by reducing acids in both mild and aggressive conditions. It also offers good oxidation resistance, up to 400 degree Celsius. It can be welded by all conventional methods. It does not require pre-heat and post-weld heat treatments. It can also be machined using any method.
SS 904L Round Bars Rods has a wide range of applications. It is used in oil refinery components. It is also used in sea water cooling devices and gas scrubbing plants. Pulp and paper factories also use grade SS 904L. acid processing plants also use this grade of stainless steel.
