Sampling for Mechanical Test of Forgings

Sampling for Mechanical Test of Forgings

Sampling for Mechanical Test of Forgings

Does anyone know the meaning or definition of the following terms:

- Separate test block or forging
- Separate forges test blank
- Custom-made forgings


RE: Sampling for Mechanical Test of Forgings

There are generally two ways that this is done.
1. A seperate part is forged, not your part at all.  A nice regular shape that is easy to cut test pieces from.  It is forged from the same material using the same heating and reduction steps that will be used for your part.
This is easy and quick.  This is a good option if the real part is very large or expensive.  On the other hand the heating and cooling rates may be nothing like those of the real part.
2. A real part is made and then cut up for testing.  You still need to decide where to cut and what direction to test.  This works for nice regular medium sized parts.

People call these various things.  I don't know the exact wording in the code.

Corrosion never sleeps, but it can be managed.
