Mill Test Certificate (EN 10204 3.1 MTC)
Engineering definition, metallurgical mechanisms, standard testing specifications, and manufacturing guidelines for closed-die forgings up to 50 kg.
Quick AnswerFeatured
An authenticated legal inspection document validated by the manufacturer's authorized quality inspector independent of the manufacturing hierarchy.
Technical Explanation & Metallurgical Principles
The EN 10204 Type 3.1 Mill Test Certificate (MTC) provides legally binding proof of quality. It documents actual chemical composition (ladle analysis), tensile properties (yield, tensile, elongation), hardness, Charpy impact energy, heat treatment cycle, and NDT inspection results traceable to the stamped heat number.
