Material 1.4539 is an advanced stainless steel alloyed with molybdenum and copper, offering outstanding resistance to reducing acids such as sulfuric acid. It provides excellent protection against ambient chlorides, minimizing the risk of pitting, crevice, and stress corrosion cracking.
1.4539 stainless steel is widely used in industries such as chemical processing, pharmaceuticals, oil and gas. Common applications include tanks, valves, heat exchangers, flanges, and manifolds. The copper content in 904L stainless steel enhances its suitability for equipment exposed to sulfuric and phosphoric acids.
For projects requiring better pitting corrosion resistance than 316 stainless steel, 904L (1.4539) is a strong choice. Its high nickel content (25%) ensures superior resistance to chloride-induced stress corrosion cracking when compared to standard austenitic grades like 304.
You can purchase 1.4539 material at competitive prices in the Evek GmbH online shop, with worldwide shipping available for premium quality round bars.
Typical uses for 1.4539 round bar include:
