casting of 17/4PH 1

[kenre]

I often investment cast bronze, but customer demand is asking for 17/4PH, strong when heat treated, and holds a sharp edge well. Not having any luck finding info on casting of this metal. Any help appreciated.

monkeydog,
i have added the link into my bookmarks, along with all the other links which i classify as "worthless" hehehhe

I am after actual casting info.
what procedures need to be followed, eg, actual pouring temps, what fluxes or covers are needed, precautions to avoid gas pickup or loss of alloys, etc.

I've had parts investment cast in 17/4PH. They were done somewhere in South Africa, but I've lost the contact info.

17-4 is a common casting material. The alloy supplier can give the standard practices.

Try talking to Carpenter.

They are usually very helpful (and they have a lot of guideline documents online).

Try contacting Dr. Russ Rosmait at Pittsburg State University. They do a lot of investment casting research.
