Corrosion Resistance
Where a level of resistance to pitting corrosion better than 316 is required 904L stainless steel may be suitable. With its high nickel content at 25% it offers improved resistance to chloride stress corrosion cracking compared to other austenitic grades such as 304.

Welding
904L stainless steel can be welded using common fusion and resistance methods. A more highly alloyed filler is recommended to give the optimum corrosion properties in the weld. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding 904L stainless steel.

Introduction
904L stainless steel combines molybdenum and copper with iron for tremendously increased resistance to reducing acids like sulphuric acid. It stands up extremely well to chlorides in the environment for low pitting and crevice corrosion, as well as stress corrosion cracking.

Applications
904L stainless steel is widely used in the chemical, pharmaceutical, oil and gas industries. Typical applications include tanks, valves, heat exchangers, flanges and manifolds. The addition of copper to the composition of 904L stainless steel aids its suitability for components such as tanks and other products used in handling sulphuric and phosphoric acid.
