CEWELD® 904L is a corrosion-resistant, solid chromium-nickel-molybdenum-copper wire for welding austenitic stainless alloys with 20% Cr, 25% Ni, 5% Mo, 1.5% Cu, and low carbon content.
Typical applications include process vessels and tanks, piping systems, agitators and rotors, as well as cast pumps and valves for the production of fertilizers, phosphoric, sulfur, and acetic acids. It is also suitable for brackish and seawater environments and in some offshore applications.

CEWELD® 904L can also be used to join Type 317L materials when improved corrosion resistance in certain media is required. To reduce the tendency to crack and hot crack, the low-melting components such as carbon, silicon, and phosphorus in this alloy are limited to a lower content. Good general corrosion resistance similar to that of similar steels/
cast steels, especially in reducing environments. Max. operating temperature 350ºC.
