An MTR is a certifiable document that communicates critical data for raw materials, such as steel and other metal alloys.

The document certifies the material’s compliance with contract and regulatory standards required for an application. The MTR is generally supplied by the material manufacturer and will follow the material throughout the supply chain. An MTR is an important document that ensures materials used in a specific application can handle the requirements of use.

What information is in an MTR?

An MTR will contain several easily identifiable characteristics of a material and many that are not so easily identifiable. Easily identifiable information includes the material’s general size and shape. Other details include heat number, material weight, classification, and grade. The Heat number is particularly important. It provides a way to trace the material back to initial production units and the process conditions during fabrication.

An MTR also includes detailed mechanical properties and chemical analysis. Chemical analysis refers to specific levels of each element aligned with the tolerances set for the material’s grade and use. Mechanical properties refer to the physical properties of a material and how they satisfy the standards set by regulatory bodies and international standards organizations.
