Advanced Fitting is a well-known manufacturer and exporter of Stainless Steel 904L Round Bars, which were designed to tolerate dilute sulfuric acid conditions. Stainless Steel 904L Bars is one of the few stainless steels that gives full resistance in such situations at temperatures up to 95 degrees F (35 degrees C) over the entire concentration range of 0 to 100 percent.


Stainless Steel 904L Rods are a low carbon, high alloy austenitic stainless steel that is not stabilised. Stress corrosion cracking and crevice corrosion are also resistant to SS 904L Round Bars. The chemical process sector, especially the manufacturing of phosphate-based fertilisers, uses SS 904L Bars extensively. Non-magnetic SS 904L Rods provide good formability, durability, and weldability.

Alloy 904L Round Bars have superior chloride SCC resistance, general corrosion resistance, and pitting resistance than SS 316L and SS 317L molybdenum higher steels due to their highly alloyed chemistry of 4.5 percent molybdenum and 25% nickel. Copper improves the resistance of Alloy 904L Bars to strong reducing acids, especially sulphuric acid. Corrosion resistance is mostly determined by the nickel content of Grade 904L Round Bars in hot, severe caustic solutions. Grade 904L Bars have proven to be a good alternative to most common stainless steels due to their nickel concentration of 25%. Grade 904L Rods are less machinable than Grades 410 and 304 due to the rate of cold work hardening.
