If you've worked in the stainless steel industry for any period of time, chances are you've seen an informational sheet similar to the one above. Some companies, like Paul Mueller, even hire full-time professionals to handle quality assurance and paperwork like these Mill Test Reports.
Keep reading to learn more about Mill Test Reports and the important role they play in the stainless steel industry. These quality assurance certificates show a metal product's compliance with international standards.
Mill test report (metals industry)
Other names for mill test reports include:. MTRs are important for both fabricators and their customers. These reports confirm that the material or product received meets specifications.
Certain sanitary products need certain material compositions to preserve the quality of the product. An MTR is proof that a material complies with the standard needed for the application.
Additionally, ASME requires that items have traceability. Companies also have to keep MTRs for up to three years after production has taken place. Companies with outstanding quality programs organize a database to keep track of these documents. Metal providers and component manufacturers have a tracking process to ensure quality and reliability. This tracking process includes at least these four items:.
The most common practice used to track heat codes is to stamp or rewrite them on the metal. Large manufacturing companies often issue a unique heat code to received material.
This provides a way for manufacturers to track material within their own production system. It also enables them to have more specific traceability for their customers.

An MTC provides traceability and assurance to the end user about the quality of the steel used and the process used to produce it. EDIT: type is declared not by chapter in the document, but by type name, so edited the numbering. The MTC will specify the type of certificate, the grade of steel and any addenda. It will also specify the results of chemical and physical examination to allow the purchaser or end user to compare the plate to the requirements of the relevant standards.
In steel industry, MTC means mill's test certificate. Some mills also call it as MTR, that is, mill's test rep. If applicable, there also should be hydro test result, UT result, hardness test result, CVN impact results, metal graphic result etc.
Usually mill will issue a table as the format of MTC of steel pipe or steel plate, to be filled with enough test results. Companies will issue a report format as MTC for steel pipes. There are mainly two types of MTC in steel industry, as for steel plates or steel pipes, there must be specific inspection scope or lists:. From Wikipedia, the free encyclopedia.

The MTR is supplied from the material manufacturer such as plate manufacturer, casting manufacturer, forging manufacturer, etc.
When the steel plate is in its molten condition, a sample is drawn out from the batch for analysis of its chemical composition. This plate is given a particular identification number known as heat number.
The heat number provides a way to trace back the steel plates to its production units and process conditions. Several plates might have identical heat number, and this is normal since that indicates both plates made from the same batch of melted material. Assume you have assigned for inspection of pressure vessel plate material at the pressure vessel manufacture shop. The vessel manufacturer provides you with MTR for purchased plate material from his supplier. Following MTR provided to you.
This is just for example; the MTR header has been removed. You will walk on the shop floor and make a visual inspection. With this checking, you make sure your MTR is the one generated for this plate.
Based on the project requirement, you might also run a visual inspection on plate edges, plate surface and also make dimensional inspection especially thickness measurement. Locate the chemical composition table and compare the percentage values in the MTR with the acceptance range in the table e. Locate the mechanical property table in the same specification.
It generally comes after chemical composition table. Similarly, compare the measured value in the MTR with the acceptance range in the mechanical properties table. For this example, you need to check yield strength, tensile strength, elongation, reduction in area and hardness. If the result of all verification on all these 3 steps were satisfactory, then the result of MTR review will be satisfactory. When you review the project specification even the inspection and test plan occasionally you might see that project requires the material test report being provided either in conformance with EN 3.
The material certificate is provided and certified by the material manufacturer. Besides, material manufacturer an independent inspection agency also shall authenticate the MTR. You typically need to see two stamps and signatures, one from the material manufacturer and the second one from inspection agency.Everything that goes into our concrete mix includes some sort of documentation.
It could be a certification, a mill test report, test record or test data, statement of conformance — and the list goes on. Some records simply state adherence to an applicable standard, but some contain data that can be overwhelming.
When we buy cement, we are provided with a cement mill certificate by the cement producer. Cement mill certificates, also called mill test reports, contain a lot of information that can prove useful for tracking changes in your concrete and controlling variability in your mix.
Usually this certificate must be included in submittal documents to show that the cement conforms to the requirements of applicable specifications, such as compositional or performance limits. Unfortunately, the other information in the document is often not used and the certificate is simply filed away, yet reading and tracking that additional information may be helpful in achieving smooth operations in the precast industry.
However, each cement producer has its own format, often supplying more information than the example shows. We will focus on portland cements for this article, and you may want to refer to the example on page 8 to follow the discussion. At the top of the example certificate, you will find the cement type. Due to overlaps in requirements and strength levels typically well above specification limits, some cements meet several types.
It is useful to consider the cement type that is more restrictive. Some of the performance information for long-term tests may apply to cement produced earlier than the time period covered, and this will be noted as shown in the example for the results of C testing at the bottom of the PHYSICAL table. Further, although ASTM explicitly details the test methods and analyses used to develop the data, there can be significant differences between producers in how often they are collected and the time periods represented.
It is important to understand that the certificate is not an analysis of a particular shipment of cement unless required by the purchaser. This is generally the case except in very large projects, as it would require extensive storage capacity and delay shipment until after the test results are obtained. The usual certificate reports the average composition and performance over some specified range of time.
It is best to understand exactly what type of average is represented by talking with the producer if it is not clear on the certificate.

Thus, normal, day-to-day production variation is averaged out, and a certificate gives no indication of such variation. Also, the samples tested on each day are usually physical composites of several samples taken over a production period, such as a shift or the full day. In some cases, these may be as frequent as hourly, meaning that the physical tests could have been done on a blend of 24 different samples, while the chemical results would be a mathematical averaging of each hourly sample.
The mill certificate number then comes from an averaging of all the days in the time period. Logically, then, no single sample — be it a small sample for laboratory testing or a ton bulk delivery — will have exactly the composition or performance reflected by the average values in the accompanying certificate.

To make this even clearer, at the height of the production period, generally in the summer, the cement actually shipped may be only one or two days old, yet the certificate shows seven- or even day strength, based on historical production data. So a fair definition of the certificate is:. If the certificate represents average cement testing, what good is it? Actually a lot, but it takes effort to gain the value of the information.
It is highly recommended to use simple control charts on which the variables discussed below are plotted each time you receive a new certificate. If concrete testing results and mix design information are plotted on similar charts, relationships may surface that are too complex to discuss here.A premium membership for higher-level suppliers.

Related Projects. So, my questions are: 1 What exactly the Mill Test Certificate is? For example, the company I am with deals primarily with stainless and carbon steel for vessel manufacture and we have to have MTRs for every piece of steel that we receive. The MTR shows the percentage of alloy used in manufacture, the tensile strength, the yield strength, reduction of area, elongation, and hardness of a sample piece to represent the whole batch of a run of material.
The MTR proves that the material we receive meets the grade we require.1000 Employee Certificate in few Minutes in Excel Step by step
This is issued by the company that does the testing. It can be from the mill itself if they have the equipment or by an outside company who tests for the mill. They would have to contact the vendor of the pipe or the mill to get the MTR if that is what they want.
Whoever bought it should be responsible for obtaining the MTR and they will need a heat number from the pipe itself to know which report they need. Hope this helps and good luck. These requirements will come from the job specs and referenced code. Additionally, some specs also call for a CMTR. This is a MTR that has the signature of the manufacture rep.
This MTR should be available from the company that the pipe was purchased from. The MTR only covers the pipe, not the coating. The approval of a third party is just a review of the MTR by a neutral party.
