What is 904L (1.4539) Stainless?

904L stainless steel is a premium, high-alloy super austenitic stainless steel designed for outstanding corrosion resistance in demanding environments. It performs exceptionally well in the presence of strong acids and chloride-rich conditions, making it the ideal choice for applications where standard stainless steels such as 304 or 316L may fail. Classified as a super austenitic grade, 904L contains significantly higher levels of nickel, chromium, and molybdenum, which provide superior protection against pitting, crevice corrosion, and stress corrosion cracking, ensuring long-term durability and reliability.

With a composition of chromium, nickel, molybdenum, copper, and carbon, 904L stainless steel delivers exceptional performance in applications that demand superior corrosion resistance, high-temperature strength, and outstanding toughness. This combination of elements ensures long-lasting durability even in harsh chemical, marine, and industrial environments. As a trusted 904L stainless steel supplier in the UK, we supply 904L plate and profiles suitable for harsh chemical, marine and industrial environments where long service life is essential.

Key Benefits of 904L
