Hydraulic 904L Seamless Stainless Steel Pipe Seamless Boiler Tubes , 6m Length
Specifications:
904L stainless steel tube (00Cr20Ni25Mo4.5Cu) has better corrosion resistance of austenitic stainless steel because of the addition of 1.5% of the copper, for the reduction of these acids, such as sulfuric acid and phosphoric acid is also very good corrosion resistance, in addition, has a low carbon in the use of welding.

Description:
Since the 904L carbon content is very low (maximum 0.020%), so there is no carbide precipitation in the case of general heat treatment and welding. This eliminates the danger of general heat treatment and welding in the intergranular corrosion. Due to the high chromium nickel molybdenum content, and the addition of the copper element, so the 904L stainless steel tube.
Even in a reducing environment, such as sulfuric acid and formic acid can also be passive.
