MIM Material Selection
MIM Material Selection
(OP)
We are looking at Metal Injection Molding to replace a high volume complex machined part. The material currently being used is C-1117 that is carbonitrided to Rc 56-60, .009 to .010 in. deep. Using MIM we are considering 4140 or 4340 that would be fully hardened and stress relieved or tempered back to the Rc 56-60 range. Because of powder availability for MIM Carbonyl Iron has also been suggested and would require carbonitriding to produce the desired surface hardness. Any thoughts?

If you provide more information on general features of the part dimensions, weight, application) we could advise more detailed

Range of materials is much wider and though there are shape limitations very oftem they could be worked out in design stage and it is much cheaper.
