Material 1.4539, also known as 904L stainless steel, is alloyed with molybdenum and copper to deliver exceptional resistance to reducing acids like sulfuric acid. It also performs well in environments containing chlorides, offering protection against pitting, crevice, and stress corrosion cracking.
This stainless steel grade is widely used in the chemical, pharmaceutical, oil, and gas industries. Typical applications include tanks, valves, heat exchangers, flanges, and manifolds. The copper content enhances its suitability for equipment handling sulfuric and phosphoric acids.
When higher resistance to pitting corrosion is needed compared to 316 stainless steel, 904L (1.4539) is an effective choice. With a high nickel content of 25%, it provides superior resistance to chloride-induced stress corrosion cracking, outperforming standard austenitic grades like 304.
