Matching billet material properties in casting
Matching billet material properties in casting
(OP)
Hello all,
I am working on a project and having a bugger of a time finding a foundry that can help me match the material properties I am currently getting in a billet part. We are using 4340 and a custom heat treat recipe to get the following properties. Is there any way that these can be matched in a casting? Thanks in advance.

- Yield 925MPa
- Ultimate 1080-1230 MPa
- Elongation 11%
- Charpy >35J @ -20C

There are a few guys here that are much better with cast steels than I am.

Here's a couple technical references for alloy steel castings:

Castings are prone to contain several heterogeneous defects like inclusions, dissolved gases, segregation, coarse grains etc.
The foundry can deliver your mechanical properties in the castings, by selecting a suitable casting alloy.
This problem is faced while reengineering from a forged part to a cast one, without understanding the limitations of cast process.
