904L is an austenitic grade stainless steel with low carbon and higher resistance to stress and crevice corrosion cracking as compared to AISI 316 & AISI 317 stainless steel grades. Due to addition of Copper, it has increased resistance to phosphoric, sulphuric and hydrochloric acid concentration. It is sometimes referred to as super austenitic stainless steel due to superiority over other 300 series austenitic steel grades. 904L is also resistant to chloride and sea water attack. 904L is primarily used in production and transport of phosphoric acid as well as in environment containing concentrations of phosphoric acid or phosphorous gas.
