904L stainless steel

904L stainless steel consists of chromium, nickel, molybdenum and copper contents, these elements give type 904L stainless steel excellent properties to resist corrosion in dilute sulfuric acid because of addition of copper, 904L commonly is used in high pressure and corrosion environment where 316L and 317L perform poorly.

904L has high nickel composition with low carbon content, copper alloy adding improve its resistance to corrosion, the “L” in 904L stands for low carbon, it is typical Super Austenitic stainless steel, equivalent grades are DIN 1.4539 and UNS N08904, 904L has better properties than other austenitic stainless steels.

904L Stainless Steel Properties

904L Stainless Steel Limitation

904L stainless steel price is expensive, due to high amount of molybdenum and nickel content, that leads to grade 904L is replaced by low cost grades, such as 316L, 317L, 2205, 6Mo and super duplex grades.

904L Stainless Steel Applications

Because of above properties, 904L stainless steel pipe can be used in many applications, these range from utility scrubber assemblies to acid and fertilizer production equipment, pulp and paper processing, seawater cooling facilities. Used in processes containing sulfuric or phosphoric acids, 904L displays its excellent resistance to corrosion from those acids. The paper, gas, pharmaceutical and chemical industries also use 904L for its resistance and use to 400-450 degrees C. Alloy 904L tubing can be welded, machined, heat treated, annealed, hardened and cold worked for many purposes.

904L Stainless steel sheet

904L stainless steel sheet is a type of superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of environments. It is known for its excellent resistance to reducing acids like sulphuric acid and its ability to withstand chlorides in the environment, which helps prevent pitting and crevice corrosion.
