904L Stainless Steel

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.
