Stainless Steel 904L Alloy, which is also known as SS 904L, is a non-stabilized austenitic stainless steel high alloy. It is an alloy with low carbon content in its chemical composition and hence a super-austenitic alloy. Alloy 904L contains copper, molybdenum and nickel in its chemical composition which makes the alloy more applicable in various environments. The addition of Copper in high alloy SS 904L helps to improve its resistance towards strong reducing acids like sulfuric acid in both aggressive as well as mild environments. SS 904L alloy is non-magnetic in most environments and offers high welding and forging properties. It exhibits superior hardness feature even in temperatures lower than cryogenic temperatures. The SS 904L alloy is also known for its resistance to stress corrosion cracking and crevice corrosion cracking. It possesses high toughness quality and resistance to pitting and general corrosion. It also exhibits good resistance against warm seawater and chloride attack. Alloy 904L consist of expensive ingredients in its composition, like molybdenum and nickel, hence its overall cost increases significantly. Due to the increased cost, SS 904L is replaced by cost-effective duplex stainless steel 2205 in most of the applications where it is applicable. SS 904L is an austenitic stainless steel with high performance steel specially designed to have excellent resistance towards moderate to high corrosion conditions. SS 904L was initially developed with intent to withstand conditions involving dilute sulfuric acid in their environments. It was exclusively designed for resistance towards corrosion in wide range of process environments. The addition of molybdenum and copper to already high chromium and nickel content in this alloy ensures excellent resistance towards corrosive media. Due to high percentage of nickel and molybdenum SS 904L displays superb resistance towards both mild and aggressive environments, and low carbon content improves its cleanliness and weld strength properties. Oshwin Overseas is recognized as SS 904L Supplier, Manufacturer, Stockist and Dealers. We have huge inventory of all kinds of SS 904L Grade Products such as SS 904L Pipe, SS 904L Tube, SS 904L Flanges, SS 904L Fasteners, SS 904L Bar, SS 904L Pipe Fittings, SS 904L Tube Fittings, 904L SS Forged Fittings, SS 904L Wire Mesh, SS 904L Sheet Plates, SS 904L Wire, SS 904L Plate.

SS 904L Properties

Heat Resistance

Grade 904L stainless steels offer good oxidation resistance. However, the structural stability of this grade collapses at high temperatures, particularly above 400°C.

Heat Treatment

Grade 904L stainless steels can be solution heat-treated at 1090 to 1175°C, following by rapid cooling. Thermal treatment is suitable for hardening these grades.

Welding

Alloy 904L can be readily welded by most standard processes. Pre-heat and post-weld heat treatments for this grade are not required.  The corrosion resistance property of 904L stainless steel is impaired in certain environments due to the redistribution of nickel, molybdenum and chromium caused by the solidification of material after welding, although this is less evident in 904L grade. SS 904L electrodes and rods are used for welding grade 904L steels according to AS 1554.6.

Fabrication of Stainless Steel 904L 

Machining This grade can be machined using any standard methods, slow speeds and positive feed minimises the alloy’s tendency to work harden and glaze. The cold work hardening rate of 904L Alloy makes it less machinable than 410 and 304 stainless steels. Hot working For Hot working process of 904L a temperature range of 1562–2102°F is recommended .Hot working is followed a solution anneal and quench but 904L stainless steel may be used without subsequent heat treatment if the hot forming is discontinued above 2012°F and the material is quenched directly thereafter. In the event of partial heating or cooling below 2012°F, or if the cooling has been too slow, hot working should always be followed by a solution anneal and quenching. 904L should be solution annealed at 1940–2084°F. Cold working 904L is quite ductile and forms easily. The addition of molybdenum and nitrogen implies more powerful processing equipment may be necessary when compared with the standard 304/304L grades. Hardening This alloy does not respond to heat treatment. It may only be hardened by cold reduction.
