SAE 904L grade stainless steel 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 intergranular 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. 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 has applications in piping systems, pollution control equipment, heat exchanges, and bleaching systems. This special grade of stainless steel also finds its application where strong reducing acids are used. Stainless Steel 904L is known to contain expensive ingredients such as nickel and molybdenum and thus is often replaced by low cost duplex stainless steel 2205.
Stainless Steel 904l has medium corrosion resistance properties such as oxidation resistance. It is a suitable austenitic stainless steel to be used in the prevention of hot seawater corrosion and chloride based attack. It resists chloride based stress corrosion cracking and acidic corrosion. SS 904 is used in acid processing equipments, gas washing, condenser tubes, heat exchangers, oils and gas treatment and paper industry. Steel 904l is non-magnetic in many environments and has supreme welding and forging features. The austenitic configuration offers superior hardness even lower than cryogenic temperature.
Corrosion Resistance Stainless steel type 904L is primarily fabricated to offer resistance to the sulfuric acid and it also possesses superior resistance to the various conditions. It has outstanding resistance to the hot sea water and chloride conditions. The significant content of nickel offers outstanding resistance to stress corrosion cracking as compare to the other stainless steel alloys. The copper content enhances the resistance to sulfuric acid and other reducing acids especially in the rigorous conditions. In the various atmospheres, stainless steel 904L grade offers moderate corrosion resistance between the standard austenitic 316L alloy and highly alloyed 6% molybdenum and equivalent to super austenitic alloy types. In the presence of rigorous nitric acid, the lower resistance as compare to molybdenum-free alloys like 304L and 310L are used. To get the highest stress corrosion cracking resistance in the crucial conditions, the steel is recommended to solution treating subsequent to cold processing.
Fabrication Heat Processing The 904L alloy possesses high resistance to oxidation though just like other alloys it goes through the structure deformation at high temperatures. The steel should not be utilized over 400oC. The solution processing like heating up to 1090oC to 1175oC and quick quenching is done. It is impossible to work harden type steel 904L through heat processing.
Forging Austenitic stainless steel 904L is a highly pure grade containing low content of sulfur. Its machining is not as such easy but it can be machined by following the standard methods. If the alloy has to be used in the rigorous corrosion cracking media, it should be annealed after cold processing.
Welding Stainless steel 904L alloy can be best welded by implementing the standard procedures. The careful processing is needed when the alloy solidifies completely and becomes prone to hot breaking particularly in the limited weldments.
