Type 904L is Abbott's most corrosion resistant stainless steel. The "L" stands for low carbon (0.030% or less). Type 904L is also an austenitic alloy. It combines nickel, chromium molybdenum and copper with iron for tremendous resistance to corrosion. AISI 904L ball applications include dispenser valves, finger pumps and spray pumps.
