Principal Design Features
|
|
This alloy is a free-machining version of Monel 400. The R405 grade contains sulfur to enhance machinability.
|
|
|
Applications
|
|
Screw machine stock for fasteners and similar high production run items.
|
|
|
Machinability
|
|
Machinability is good. High-speed tool steels should be used with oil base lubricants. Turning is done at speeds of 140-160 surface feet per minute with a feed rate of approximately 0.004 in./revolution.
Drilling is done at 50-65 surface feet per min. with feed of 0.003 in./revolution.
|
|
|
Forming
|
|
The alloy is especially adaptable to screw machine operations.
|
|
|
Welding
|
|
Standard welding methods may be used.
|
|
|
Heat Treatment
|
|
The alloy may be annealed but does not otherwise respond to heat treating.
|
|
|
Forging
|
|
Due to the intentional sulfur content this alloy should not be forged.
|
|
|
Hot Working
|
|
Hot working is not recommended.
|
|
|
Cold Working
|
|
The alloy is readily cold worked, especially in screw machine operations.
|
|
|
Annealing
|
|
Anneal at 1700 F and air cool. A stress relief only anneal may be done at 1000 F for 1-1/2 hour followed by air cool.
|
|
|
Hardening
|
|
Hardens due to cold working only.
