Washington Alloy, TF904L-16 01, Electrode, E904L-16; 3/32 in, High Alloy Austenitic Stainless Steel, 68,000 psi Yield Strength

904L is a high alloy austenitic stainless steel electrode with extra low carbon content intended for use in severe corrosive conditions. Residual elements C, Si, P, S and N are kept at much lower levels in order to keep the weld metal from hot cracking and fissuring. USA 904L is designed for joining 20% Cr-25% Ni-4.5% Mo1.5% Cu stainless steels used to manufacture and repair processing equipment, tanks, vessels, and process piping handling acetic acids, sulfuricacid solutions and many chloride containing media. Other uses Include cooling units for sea water and river water purification plants and for cladding lower alloy steels when used in many corrosive media environments. USA 904L is also used for joining AISI type 317 where improved corrosive resistance in specific media is required.
