A Material Test Report (MTR), also known as a Mill Test Report or Certificate of Test, is a document that provides essential information about the properties and quality of a specific material or product, typically metals such as steel, alloys, or other materials used in construction, manufacturing, or engineering applications.

An MTR is typically provided by the manufacturer or supplier of the material and is essential for ensuring that the material meets the required specifications and standards for the intended application. It serves as a crucial quality assurance and traceability document.

Key Elements of an MTR

When it comes specifically to steel, an MTR generally includes the following key information:

1. Material Identification: This section includes details about the steel, such as its type, grade, and any relevant specifications specific to its wear-resistant steel properties. It may also specify any applicable industry standards and codes related to wear resistance.

2. Chemical Composition: The MTR will list the chemical composition of the steel, including the percentage of various elements present and highlighting the elements that make up wear-resistant steel. This is important to ensure that the steel meets the required composition for its intended use and wear resistance.

3. Mechanical Properties: The report will provide information about the mechanical properties of the steel to determine how it will perform under different conditions. These properties include:

    • Tensile Strength: The maximum stress wear resistant steel can withstand before breaking.
    • Yield Strength: The stress at which the material begins to deform plastically, impacting its wear performance.
    • Elongation: A measure of the steel’s capacity to undergo elongation or deformation under tensile stress, typically expressed as a percentage.
    • Hardness: A measure of the material’s resistance to wear and abrasion, often critical for wear-resistant steel applications.
    • Impact Resistance: This measure is important for wear-resistant steel used in applications where the material is exposed to sudden and unpredictable forces, such as in the design of wear-resistant components, machinery parts, or equipment operating in abrasive environments. Impact resistance is typically measured through controlled impact tests, which evaluate how wear-resistant steel can absorb and dissipate the energy of an impact without compromising its wear resistance properties.


4. Heat Treatment: If the wear-resistant steel has undergone any heat treatment processes, such as annealing, quenching, or tempering, the MTR will detail the specifics of these processes as heat treatment can influence wear resistance.

5. Manufacturing Process: The MTR may describe the processes involved in manufacturing the wear-resistant steel, including details about casting, rolling, forging, or other forming methods.

6. Test Results: The MTR will present the results of various tests conducted on the wear-resistant steel to help ensure that the steel meets the required quality standards. These tests include:

    • Chemical analysis
    • Mechanical testing, with a focus on properties related to wear resistance
    • Non-destructive testing (NDT)
    • Hardness testing
    • Microstructural analysis relevant to wear resistance
    • Any other relevant tests

7. Traceability Information: MTRs often include information about the production batch or lot number, heat numbers, and material identification markings which helps in tracking the origin of the material and any potential issues if they arise.

8. Certification and Compliance: The MTR may include signatures or stamps from authorized representatives of the manufacturer or supplier certifying that the wear-resistant steel meets the specified standards, codes, or customer requirements for wear-resistant applications and is suitable for its intended application.

Every MTR plays a crucial role in industries where the quality and performance of materials, such as wear-resistant steel, are of paramount importance. These reports help customers, engineers, and other stakeholders verify the quality of the materials they are using and ensure that they meet the necessary standards for safety and performance.
