What are 904L's best qualities?
- 904L grade stainless steel boasts an exceptional low carbon content and high copper concentration, significantly maximizing its resistance against potent acids such as sulphuric acid. Its substantial nickel content ensures robust defense against stress corrosion cracking. Furthermore, 904L is remarkably resilient to crevice corrosion. Whether in warm waters or chloride-rich environments, this stainless steel endures both moderate and aggressive conditions with outstanding performance.
- 904L stainless steel exemplifies exceptional heat resistance, enduring temperatures up to a striking 400 degrees Celsius. Heat treatable between 1090 to 1175 degrees Celsius followed by rapid cooling, this treatment method is ideal for hardening 904L steel, ensuring enhanced durability and performance.
- Due to its unique composition, 904L steel is nonmagnetic. It offers superb weldability, formability, and toughness across varied conditions, making it versatile for numerous applications.
- 904L steel accommodates all standard welding techniques seamlessly, eliminating the necessity for pre-heat or post-weld heat treatments, thus simplifying the welding process.
What is 904L used for?
904L steel's superior purity and low sulfur content make it invaluable in both luxury and industrial applications. It is prominently utilized in the creation of high-end wristwatches. Industrial applications include:
- Seawater cooling devices.
- Wiring in electrostatic filtration devices.
- Oil refinery components.
- Gas scrubbing plant parts.
- Machinery for pulp and paper processing.
- Parts in machines utilized in sulfuric, acetic, and phosphoric acid processing plants.
Fabrication Data
- Alloy 904L is effortlessly welded and processed using conventional shop fabrication methods, maintaining high efficiency and performance.
Cold Forming
- 904L showcases considerable ductility and forms with ease. The inclusion of molybdenum and nitrogen may necessitate stronger processing equipment compared to standard 304/304L grades.
Hot Forming
- Hot working procedures for 904L require a temperature range of 1562 to 2102°F (850-1150°C). Post-hot working, a solution anneal and quench are normally recommended. However, if hot forming is halted above 2012°F (1100°C) and followed immediately by quenching, no further heat treatment is needed. Ensure the entire workpiece is quenched from above 2012°F (1100°C). If cooling occurs below this temperature or is too slow, follow up with solution annealing and quenching. 904L should be solution annealed at 1940-2084°F (1060-1140°C).
Machining
- The cold work hardening rate of Alloy 904L poses more machining challenges compared to 410 and 304 stainless steels.
Welding
- Alloy 904L is compatible with most standard welding methods. The austenitic structure and balanced alloying elements distribution minimize segregation during welding. Redistribution of elements like molybdenum, chromium, and nickel can occur, but 904L's lower segregation ensures superior corrosion resistance. It can be welded with or without filler metal, typically using a filler of the same composition.
- Welding consumables suited for 904L include the 20 25 CuL covered electrode and 20 25 CuL wire, ensuring optimum weld quality and performance.
