Inconel 625 casting alloy

[ZVGFoundryNL]

Inconel 625 seems to obtain it's mechanical properties by coldworking. My question: What results can I expect in the 'as cast' condition knowing that it is molted by induction and sand-casted.

What kind of castings do you intend to produce? Can you usevacuum induction melting?


Inconel 625 is not a cast alloy,what is the concern about? The data sheet provided below does not mention that mechanical properties are achieved by cold forming. Yes cast properties will be lower to the wrought ones. If you control impurities and have a clean metal free from tramps perhaps you can get the properties.

From my experience I can say that do not promise mechanical properties in a casting for such alloys. Recently I had some rejections due to low Elongation though I had not promised to deliver with mechanical properties certificate

The sand cast equivalent of inconel 625 is ASTM A494 CW6MC. It is not intended to be used without a solution anneal heat treatment.

Check also Norsok material data sheet MDS-N02.
