Material Test Reports (MTR Documentation)

PNW Sanitary provides Material Test Reports (MTRs) for stainless steel fittings, tubing, and other sanitary components. MTRs verify material chemistry, mechanical properties, and heat/lot traceability for compliance and quality control.

All MTRs are issued on official PNW Sanitary letterhead and delivered electronically as PDF files.

What Is Included in an MTR?

An MTR (also known as a Mill Test Report) typically includes:

  • Product description and material grade
  • Heat/lot number
  • Chemical composition analysis
  • Mechanical properties (where applicable)
  • Reference to applicable ASTM standards

Which Products Include MTRs?

  • Most 304 and 316L stainless steel fittings
  • Most 304 and 316L stainless steel tubing

Gaskets, clamps, and certain accessories typically do not have MTRs. If an item does not have an available MTR, we will let you know when you request it.

Need a Certificate of Conformance (COC)?

If you only need a document confirming conformance (and not full chemistry), a COC may be more appropriate.
