Attention Engineers: MTR's and Certs of Conformance are always free at OnlineMetals.com

If you'd like to receive Mill Test Reports, just click the check box, in Step 4 of your check out, and we'll send them via e-mail, when your order ships.



What's a Mill Test Report? (AKA: MTR or Material Test Report.)

It's a certificate that the mill gives to distributors like us, that confirms that the metal is what they say it is. They make it, and then test it to make sure it conforms to the following:

  • ASTM and ASME standards
  • Specific Size, Shape, and/or Diameter specifications
  • Chemical specifications.
  • Proof of Origin

Certificate of Compliance: (AKA: Certs or C of C's.)

Some metals don't come with MTR's. Copper C110, for example. In that case, Metal Service Centers create their own "Certificate of Compliance" documents to stand behind the product, and confirm it is what they say it is. OLM is happy to provide these. Just give us a call. (800) 704-2157

Do I need MTRS or Certs?

If you're asking this question, then you probably don't. They are generally only required for manufacturing applications, particularly in the aerospace field.

How will I get the MTR's

In order to minimize our costs and keep things as efficient as possible, we email you PDFs of all of your MTRs with your shipment notification.
