Austenitic SS 904L is a low carbon, nickel-chromium alloy with additions of copper and molybdenum. It is majorly used in various chemical environments and even in reducing conditions due to its excellent resistance to corrosion.
It is suitably used in sulphuric acid, phosphoric acid, and acetic acid environments. This grade comes as an exemplary alternative when grade 304 and grade 316 fail to perform under corrosive environments. The chromium content in the grade forms a protective passive layer to restrict general corrosion. The stainless steel chemical formula constitutes a high amount of nickel content, majorly promoting its austenitic structure.
