904L Stainless Steel
Overview: 904L Stainless Steel
904L stainless steel, developed by a pioneering French company, is a superior acid-resistant alloy with a low-carbon, high-nickel, and molybdenum composition. This grade exhibits excellent conversion between activation and passivation states, showcasing remarkable resistance to corrosion, notably in non-oxidizing acids like sulfuric, acetic, formic, and phosphoric acid. It stands out for its exceptional pitting resistance in chloride-rich environments and is also immune to crevice corrosion and stress corrosion.
904L excels in resisting various concentrations of sulfuric acid below 70°C, as well as corrosion in acetic acid and mixtures of formic and acetic acid at all concentrations and temperatures under atmospheric pressure. Featuring a fully austenitic structure, 904L material is not prone to ferrite and α-phase precipitation, setting it apart from conventional austenitic stainless steels with its high molybdenum content
904L Stainless Steel Features
904L stainless steel features a minimal carbon composition (max 0.020%), preventing carbide precipitation during heat treatment and welding, and thus intergranular corrosion. Its high chromium, nickel, molybdenum, and copper content enhances corrosion resistance, allowing passivation even in reducing environments like sulfuric and formic acids. The substantial nickel content provides excellent resistance to pitting and crevice corrosion, especially in chloride-containing environments. 904L excels in sulfuric acid concentrations up to 98% and pure phosphoric acid up to 85%, though its performance can vary with impurities in industrial phosphoric acids. It is effective in hydrochloric acid up to 1-2%, outperforming conventional stainless steels. Additionally, the high nickel content ensures strong resistance to stress corrosion cracking in chloride solutions, concentrated hydroxide solutions, and hydrogen sulfide-rich environments, making 904L ideal for high-risk industrial applications.

904L Stainless Steel FAQs
Is 904L stainless steel magnetic?
No, thanks to its enhanced nickel and molybdenum content, Alloy 904L outperforms other austenitic stainless steels. It remains non-magnetic under all conditions, offering superior weldability and formability.
Comparing stainless steel 316l vs 904l
The key distinction between stainless steel 316L and 904L lies in 904L’s enhanced composition, featuring significantly higher levels of nickel and chromium, along with copper. This unique blend affords 904L superior corrosion resistance, bolstered by the additional copper and molybdenum. Price-wise, 904L generally costs about 2-3 times more than 316L upfront. However, the durability and extended service life of 904L stainless steel can render it more cost-effective in the long run, despite its higher initial investment.
Do you have secondary 904L stainless steel sheet?
