Origin of the porosity in Steel casting
Origin of the porosity in Steel casting
(OP)
We have a problem on part casting, in CF38M. All the part have gaz defects.
Any solutions ?
I know that there is a lot of origins of this porosity, but how to find wich is the source of this defect.
This is a good paper from American Foundry Society. But how can i use these informations to avoid the porosity ?
