UNS N08904 (904L, 1.4539) Stainless Steel Seamless Pipes
UNS NO8904, commonly known as 904L stainless steel, is a low carbon austenitic nickel-chromium stainless steel with additions of molybdenum and copper. 904L pipes, 904L sheets and plates and other 904L product forms products are mainly used where the corrosion resistant properties of 316L and 317L are inadequate, especially in severe corrosive conditions.
Stainless steel 904L plates, 904L pipes, and 904L fittings are widely used for manufacturing tanks, vessels, piping, heat exchangers, and other equipment used for handling sulphuric, phosphoric and acetic acids, bleaching operations in the pulp and paper industry. In addition, 904L tube is widely used for general piping requirements in the oil and gas, chemical and pharmaceutical industries.
