Mill Test Certificate
MTCs are also the most commonly falsified document in low-cost supply chains, which is why verifying material independently is worth more than filing the paperwork.
A mill test certificate is the steel mill's record of a heat's chemical composition and mechanical properties. It is the document that proves what material you actually received.
- Contains
- Heat number, chemistry, mechanical results
- Issued by
- The steel mill
- Verification
- Spectro analysis on receipt

Quotable facts from Avadh Techno Forge, Gundasara, Gondal, Rajkot.
- Contains: Heat number, chemistry, mechanical results
- Issued by: The steel mill
- Verification: Spectro analysis on receipt
- Certificate type: Usually EN 10204 3.1
What It Contains
Heat number, chemical analysis element by element, mechanical test results including tensile, yield and elongation, the standard the material conforms to, and the mill's declaration. Impact test results appear where specified.
Verifying It Independently
Spectro analysis on the incoming lot is the only reliable verification. We test every heat lot against its certificate before production, which catches both innocent mix-ups and deliberate substitution at the gate rather than at the customer's assembly line.
