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 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.
316L, A lower cost alternative, but with much lower corrosion resistance.
6Mo, A higher resistance to pitting and crevice corrosion resistance is needed, a large range of super austenitic grades is available, with selection based on intended environment.
2205, A very similar corrosion resistance to 904L, with the 2205 having higher mechanical strength and at a lower cost to 904L. (2205 not suitable for temperatures above 300°C, and not appropriate for difficult forming.)
Super duplex, Higher corrosion resistance is needed, together with a higher strength than 904L
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.
