The MTR serves as proof and a reference that a given material meets or exceeds the standards required for an application. This document applies to sanitary products, infrastructure projects, and other applications where specific compositions and tolerances are required to ensure safety.

For instance, a metal forge will generally need to include an MTR with any raw metal or alloy created in its facility. The document applies to a number of individuals and companies utilizing various raw materials and finished products. Why Are Material Test Reports (MTRs) Important?Ī Material Test Report is important for a number of reasons. Commonly utilized heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, carburizing, normalizing, and quenching. This can include hardening or softening of a material. This can include heating or chilling, often to extreme temperatures, to achieve the desired result. Heat treatment processes alter the physical and/or chemical properties of a material. This includes chromatography, gravimetric analysis, ICP analysis, OES analysis, SEM-EDS analysis and XRF analysis. What Is Chemical Analysis?Ĭhemical analysis includes common qualitative and quantitative methods of determining material composition. Examples of mechanical properties are the absolute value of elasticity, tensile strength, elongation, hardness, and fatigue limit. Mechanical properties are physical properties that a material exhibits upon the application of forces. The material grade applies to all forms of metals and alloys. It indicates the purpose of use and mechanical properties, as well as chemical composition of a material.

Material Grade is usually in the form of a letter code, series of letters, or a combination of letters and numbers. It is a quality control mechanism that is utilized at every point in the supply chain, from foundry to finished goods.

This code is used to track material within a production system and provides specific traceability to customers. The manufacturer is responsible for tracking activities once the metal ships to a manufacturing facility. Some metal suppliers will utilize a more uncommon practice of including tracer numbers. The most common practice used to track heat codes is to stencil, write, or imprint them on the metal’s surface. The last three (and sometimes four) indicate the melt number.The second digit indicates the year in which the material was melted.The first digit corresponds to the furnace number.However, the vast majority use the following structure to indicate material characteristics and composition: There is no uniform structure to how heat number and associated information are displayed on materials. A method for tracing mill heat codes to manufacturer heat codes.This process will include at least these four items: A lot number is used to identify a production run or batch as a means of quality control. A heat number is best associated with a manufacturing lot number. The heat number is considered the only way to track steel or alloy plate, pipes, and tubes back to their MTR/MTC. Thus, the quality and reliability of metals used in an array of manufacturing operations and applications can be ensured. The number is used as a tracking method by metal providers and component manufacturers. It provides a traceable record of the batch that the piece came from. Edition Year and Type of Specifications MetĪ heat number, also called heat code, is a reference for a piece of metal.

For instance, in the steel industry, an MTR may include some or all the following information: What Information Does A Material Test Report (MTR) Contain?Ī material test report can contain varying information based on the material to which the report belongs. Other common names for Material test reports include:Ģ. This is why MTRs are of critical importance during and after manufacturing processes. Failure to accurately communicate a material’s physical and chemical properties can lead to issues that may result in catastrophic failure or even loss of life. Standards, such as ANSI and ASME, that require MTR certs ensure that manufacturers are working with materials suited for their intended purpose. These qualities are necessary for assuring proper compliance, reporting, and application purposes. REMOTE CONSULTING AND IMPLEMENTATION SERVICESĪ Material Test Report (MTR), also known as a mill test report, acts as a certified record of a material’s physical and chemical properties.
