Global leader in stainless steel Coil fabrication services
Type 904L is a high alloy austenitic stainless steel that is renowned for its corrosion resistance. 904L alloy (UNS N08904) is a super austenitic stainless steel that may be used in a variety of process settings and has moderate to high corrosion resistance. The high chromium and nickel content, along with molybdenum and copper, ensures good to outstanding corrosion resistance. With a highly alloyed chemistry (25% nickel and 4.5% molybdenum), 904L offers better resistance to chloride stress corrosion cracking, pitting, and general corrosion than 316L and 317L molybdenum reinforced stainless steels. The 904L alloy was originally created to withstand dilute sulfuric acid conditions. It is also resistant to most organic acids and other inorganic acids, including hot phosphoric acid. 904L alloy is easily weldable and may be handled using typical shop fabrication procedures.

What are 904L's best qualities?
- This grade of stainless steel contains little carbon content. It is high in copper, which increases resistance to strong acids like sulphuric acid. The high concentration of nickel makes it resistant to stress corrosion cracking. It is also extremely resistant to crevice corrosion and stress corrosion cracking, which can affect other forms of steel. It can be employed in a variety of demanding conditions, including warm waters and chloride exposure. It's suitable for both moderate and aggressive conditions.
- This type of stainless steel is extremely heat resistant, withstanding temperatures up to 400 degrees Celsius. It is heat treatable at temperatures ranging from 1090 to 1175 degrees Celsius, followed by quick cooling. This type of heat treatment is an excellent choice for hardening 904L steel.
- This type of steel is nonmagnetic due to its composition. It has great weldability, formability, and toughness in a variety of circumstances.
- 904L steel can be welded using any normal method, with no need for pre-heat or post-weld heat treatments.
What is 904L used for?
As mentioned earlier, 904L steel is the stainless steel used in the construction of watches. In industrial settings, it is valued for its high purity and its low sulfur content. A few of the places 904L is used includes:
- Seawater cooling devices.
- Wiring in electrostatic filtration devices.
- Oil refinery components.
- Gas scrubbing plant parts.
- Machinery for pulp and paper processing.
- Parts in machines used in sulfuric, acetic and phosphoric acid processing plants.
Fabrication Data
- Alloy 904L can be easily welded and processed by standard shop fabrication practices.
Cold Forming
- 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.
Hot Forming
- Hot working procedures require temperatures ranging from 1562to2102°F (850-1150°C). Normally, hot working should be followed by a solution anneal and quench; however, for 904L, if hot forming is stopped at a temperature over 2012°F (1100°C) and the material is quenched immediately after, the material may be utilized without further heat treatment. It is critical that the entire workpiece be quenched from temperatures above 2012°F (1100°C). When partial heating or cooling falls below 2012°F (1100°C), or if cooling is too sluggish, hot working should always be followed by a solution anneal and quenching. 904L should be solution annealed at 1940-2084°F (1060-1140°C).
Machining
- The cold work hardening rate of Alloy 904L makes it less machinable than 410 and 304 stainless steels.
Welding
- Most conventional welding methods are compatible with Alloy 904L. Austenitic plate materials have a uniform austenitic structure and an equitable distribution of alloying elements. Certain elements, including as molybdenum, chromium, and nickel, are redistributed during solidification after welding. These segregations stay in the cast structure of the weld and can reduce corrosion resistance in certain situations. Segregation is less noticeable in 904L, which is typically welded with a filler metal of the same composition as the base metal but can also be welded without filler metal.
- The welding consumables for 904L are 20 25 CuL covered electrode and 20 25 CuL wire.
What are the applications that 904L stainless steel coils can be used?
