If you’ve ever seen a Road Runner cartoon, you know that Wile E. Coyote tries everything to capture his prey, and often orders materials from the fictitious Acme Corporation. If any of these materials came with a Mill Certification Sheet and the Coyote took the time to read it, he might be spared the spectacular failures of his complex products – and eventually dine on Road Runner.

This Mill Cert, also known as a Certified Material Test Report, Mill Test Report, or simply a Cert Sheet, is part of the paperwork that arrives with a sheet metal shipment. The Mill Cert includes much more information than the name of the buyer and seller. If you know what you’re looking for, you can learn about some of the metal’s properties and predict how it will react in your facility.

The way sheet metal behaves during stamping is influenced by its tensile properties, chemical composition, grain size, and surface profile. Information about each of these may be included on the mill cert, providing traceability and assurance to the end user about the quality of the steel used and the process used to produce it.

Carefully examining an mill cert can help prevent expensive and time-consuming problems, maximizing uptime, and help with your root-cause analysis of stamping splits

What You Will Learn: 

Students learn about the information that is typically contained on Mill Certifications. We discuss how retaining that information may be used to ensure that received coils meet your specifications, monitor success and issues with coils in production, and monitor variation in coil properties over time.
