A material test report, often called an MTR, is a document that helps verify the material used to manufacture a metal component. In sanitary processing, an MTR is commonly requested for stainless steel fittings, tubing, valves, and other components where material traceability matters.
What information is included in an MTR?
An MTR typically includes the material grade, heat number, chemical composition, and mechanical properties associated with the material. These details help confirm that the stainless steel matches the expected specification, such as 304 or 316L. The heat lot number is especially important because it connects the finished part back to a specific batch of material.
Why customers request MTRs
Customers may need an MTR for quality records, internal documentation, project specifications, or audit support. It can also help engineering, QA, and procurement teams confirm that the supplied material aligns with their process requirements. An MTR does not replace system-level validation, but it is a useful traceability document for many hygienic processing applications.
How to request one
The best time to request an MTR is before placing an order, especially when documentation is required by your project or quality team. On our website, we have an option to include MTRs during the checkout process. Customers can also submit an MTR request after an order has been placed. Provide the part number, order number (if available), material grade, quantity, and any documentation requirements your team needs reviewed.
