Certifications & Standards

All materials meet published ASTM and AMS specifications. Mill Test Reports available on request.

What is a Mill Test Report?

A Mill Test Report (MTR), also called a Certified Material Test Report (CMTR), documents the chemical composition and mechanical properties of a specific heat of material. MTRs are produced by the mill during manufacturing and trace the material from its source.

MTRs are essential for B2B buyers in aerospace, defense, medical, and structural applications where material traceability is required by regulation or contract.

An MTR typically includes:

  • •Chemical composition (element percentages)
  • •Mechanical properties (yield, tensile, elongation, hardness)
  • •Heat number and lot traceability
  • •Applicable specification compliance (ASTM, AMS, etc.)
  • •Mill name and inspection certification

How to Request Certifications

Paper Mill Test Reports ship with every order automatically. For a digital copy, request an e-MTR from your order lookup page or account portal after placing your order. For RFQ orders, mention MTR requirements in your request. You can also specify additional certification requirements (e.g., ASTM B209, AMS 4045, domestic melt cert) in the checkout notes or RFQ form.
