Metallurgy & Testing

Scot Forge on-staff, in-house metallurgists and quality inspectors implement testing methods that support production, quality control and research and development for our customers. Our expertise includes:

  • Nondestructive examination
  • Destructive testing
  • Metallurgy review and support
  • Failure analysis

Nondestructive Testing

Guaranteed Quality Requirements Lower Costs

Scot Forge staffs an inspection team of industry certified personnel trained to use the latest and most advanced equipment in the field. Our on-site NDE services utilize Magnetic Particle, Liquid Penetrant and Ultrasonic Testing methods that are Nadcap accredited, when contracted. These services guarantee your forgings meet the quality requirements essential for the intended application, saving time and money.

Nondestructive examination methods

  • Ultrasonic inspection (UT): contact a-scan testing
  • Magnetic particle (MT): wet fluorescent, dry powdet
  • Liquid penetrant (PT): water washable fluorescent, visible dye
  • Elemental analysis using optical emission and x-ray fluorescence spectrometry


All personnel performing nondestructive testing at Scot Forge are certified in accordance with written procedures that meet and exceed the guidelines of ASNT Recommended Practice No. SNT-TC-1A.[1] and NAS‑410.2

Additionally, all of our Level III inspectors are third-party-certified or in the process of becoming certified as ASNT NDT Level III and ASNT ACCP Professional Level III.

Our Nondestructive testing systems is accredited to the very stringent Nadcap Nondestructive Testing conformity assessment.

Mechanical Testing

Scot Forge metallurgists also use an array of mechanical, destructive test methods to understand part performance and material behavior under different load environments. By discovering the elasticity and failure threshold of a part we can ensure part reliability in the field. 

Mechanical testing methods

  • Tensile
  • Dynamic tear
  • Hardness
  • Crack Tip Opening Displacement (CTOD)*
  • Fracture toughness (KIC, JIC)
  • Fatigue, crack growth
  • Charpy impact (700 ft·lbf machines; -321 °F through 200+ °F)
  • Nil-Ductility Transition Temperature (NDT)


Metallurgical Analysis

Our degreed metallurgical team has more than 175 years of combined experience. Through active participation in numerous industry associations, including ASTM, AGMA, AMS, FIA and the International Metallography Society, Scot Forge stays on the cutting edge of forging technology and advancement.

Metallurgical test methods

  • Metallography
  • Grain size
  • Microcleanliness
  • Macrostructure
  • Corrosion
  • Optical emission spectroscopy
  • Phase identification and phase count
