What are the basic feature should have in a material test report other than mechanical chemical test report. I got some mtr of 316ss from various supplier how do I confirm that this one is from original melting shop.

RE: Mill MTR
Many large producers will purchase material from commercial sources other than their own shops. This does not mean the material is not of the same quality as the material from their own shop, just they have outsourced some of the processing.
What I guess I am saying is that instead of worrying about whether or not the MTR is from the original melt shop, you should be worried whether or not you can trust the company that issued the MTR. If you trust the source of the MTR, it really doesn't matter where the melt shop is. If you don't trust the source of the MTR, then your due diligence should include some checks to insure the material is what it represented to be.

You are seeking an information from a source that is doubtful, do not go there. Else, carry your independent check. Normally, if you buy from SAIL , you are safe .
Essentially, the MTR must provide the chemical and physical properties with suitable identification to ensure traceability.
RE: Mill MTR
To be technically accurate though, any information reported that was not generated by the entity providing the cert should be backed up with the original MTR that was the source of that data or at least refer to the source.
Ultimately the spec that you ordered to dictates what information must be provided.

RE: Mill MTR
Importantly, if you do not trust the manufacturer do not buy from the manufacturer. As a part of your incoming material inspection, you can perform your own testing on a sample from the lot to verify that the material meets your requirements with regards to chemical and mechanical testing. This is money well spent. I have rejected materials based on independent test results not meeting the standard.

Trust but verify still works.

Normally, tracing the material all the way back to the original mill run is unnecessary. All you are usually concerned about is the metallurgy/properties/quality of the material coming from the immediate supplier.
