Corrosion testing and ferrite testing
March 10, 2010
Engineer - India
I work for a valve manufacturing company.Few days back we recd an order for CF8M casting stating that the following tests are to be conducted on the casting:
I have heard somewhere that some minimum amount of ferrite(5-8%) is required in a CF8M casting to make it corrosion resistant.
So what exactly should be the ferrite content in these castings so that it passes the corrosion test?
& to pass the ferrite testing what is the acceptance level of ferrite content in CF8M castings?
Waiting for your valuable reply....
