Material Test Report (MTR)
/glossary/mtrDetailed test results document covering chemistry, mechanicals, and dimensional compliance.
In detail
Material Test Report (MTR) is the comprehensive document detailing all test results for a specific heat of steel, including chemical composition analysis (C, Si, Mn, P, S, Cr, Mo, Ni), mechanical test results (yield strength, tensile strength, elongation, hardness), and dimensional verification. MTR is synonymous with MTC in common usage, though technically MTR refers specifically to the test data portion. The MTR provides the evidence of compliance to specified grades like SA192, SA210, or ASTM A53.
Where you'll meet this in procurement
You will meet Material Test Report (MTR) in inspection plans, dispatch packs, and tender checklists. Keep heat identity, certificate type, and any third-party witness tied to the order so Material Test Report (MTR) is usable evidence at site acceptance—not a loose attachment after delivery.
