| Principal Design Features | 904L is an austenitic stainless steel designed for moderate to high corrosion resistance. Its low carbon content improves cleanliness and weld strength. | |
| Applications | Utility scrubber assemblies, acid and fertilizer production equipment. | |
| Machinability | Slow speeds and positive feeds will minimize this alloy's tendency to work harden and glaze. Use chip breakers where possible to overcome problems with long draggy chips. | |
| Welding | Most common fusion and resistance methods may be employed. For maximum corrosion resistance, it is recommended to use filler metals of equal or higher alloy content. | |
| Hot Working | Hot work should proceed after uniform heating to 2000-2200 F. Doe not work the material at less than 1800 F. Full annealing should follow any hot work to reattain maximum ductility and corrosion resistance. | |
| Cold Working | Although higher forces are required, 904L will respond in a similar fashion to other austenitic stainless steels like 304, 316 or 317. Most common operations can be successfully performed. | |
| Annealing | 1920-1990 F (1050-1090 C), rapid cooling. | |
| Hardening | This alloy does not respond to heat treatment.. It may only be hardened by cold reduction. | |
