SAW Submerged arc
SAW stainless steel austenitic filler metal with excelent corrosion resistance
Tanks and process vessels, Piping systems, agitators, rotors, cast pumps and valves for use in the fertilizer,
phosphoric,sulphuric and acetic acid plants
phosphoric,sulphuric and acetic acid plants
SA 904L is used for welding materials of similar chemical composition which are used for fabrication of
equipment and vessels for handling of sulfuric acid and many chloride containing media. This filler metal may
also find applications for joining Type 317L material where improved corrosion resistance in specific media is
needed. In order to reduce the propensity for fissuring and hot cracking, the low melting constituents such as
carbon, silicon, and phosphorus are controlled to lower levels in this alloy. Best to be used with our fused flux
FL 880.
