Stainless Steel 904L
Stainless Steel 904L is stocked by 23 North American distributors and produced by 28 large mills. Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required
This material is stocked primarily in Flat Rolled Products by 10 distributors but is also available to a lesser extent in Tubular Products, Wire Products, Piping Components, Bar Products, and Structurals.

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.
Utility scrubber assemblies, acid and fertilizer production equipment.
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.
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 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.
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.
1920-1990 F (1050-1090 C), rapid cooling.
This alloy does not respond to heat treatment.. It may only be hardened by cold reduction.
