ALLOY 904L • UNS N08904 • WNR 1.4539
904L stainless steel is also known as UNS N08904, WNR 1.4539, KS STS 317J5L, BS 904S13,WERKSTOFF NR. 1.4539, SUS 904l, EN X1NiCrMoCu25-20-5,SS2562 and DIN 17440.It is a fully austenic low-carbon variety of stainless steel with additives of molybdenum and copper. Its high nickel and chromium content make it corrosion resistant in both oxidizing and reducing environments. The copper and molybdenum help to make it resistant to pitting as well as crevice corrosion. The nickel content makes it resistant to chloride SCC and the low proportion of carbon makes it resistant to inter-granular corrosion. It is considered especially well-suited to handling sulfuric acid and phosphoric acid, though at high temperatures it may be subject to stress corrosion cracking.
