Material 1.4539, also known as 904L stainless steel, is a high-alloy steel that contains molybdenum and copper, providing exceptional resistance to reducing acids such as sulfuric acid. It is highly resistant to chlorides, helping to prevent pitting, crevice, and stress corrosion cracking.
This stainless steel is widely used in the chemical, pharmaceutical, oil and gas industries for products like tanks, valves, heat exchangers, flanges, and manifolds. The copper content makes it especially suitable for components in environments involving sulfuric and phosphoric acids.
When superior resistance to pitting corrosion compared to 316 stainless steel is needed, 904L (1.4539) is an excellent choice. With a high nickel content of 25%, it offers enhanced protection against chloride stress corrosion cracking compared to other austenitic grades like 304.
You can purchase 1.4539 material at competitive prices from Evek GmbH’s online shop, with high-quality round bars available for worldwide shipping.
