There are caveats when getting an MTR.
One of the worst is the use of the word "typical" in the heading of the actual report.
Another problem that has shown up is not properly tying the material to the MTR.
There is quite a lot misuse of the word "lot number" instead of heat number.
Just make sure your MTR matches the particular material you receive.
This will probably escalate as manufacturers are scrambling to raw materials due the present shortages in the metal markets.
