Material 1.4539 is an alloy of molybdenum and copper with iron, designed for exceptional resistance to reducing acids like sulfuric acid. It also offers strong protection against chlorides, reducing the risk of pitting, crevice, and stress corrosion cracking.
Stainless steel 1.4539 is commonly used in the chemical, pharmaceutical, oil and gas sectors. It is ideal for manufacturing tanks, valves, heat exchangers, flanges, and manifolds. The addition of copper enhances its performance in handling sulfuric and phosphoric acids, making it suitable for related equipment.
When higher resistance to pitting corrosion is needed compared to 316 stainless steel, 904L (1.4539) is a reliable choice. Its high nickel content (25%) provides greater resistance to chloride stress corrosion cracking than other austenitic grades such as 304.
