Mechanical Testing

Tensile testing is done by computer automated testers to improve accuracy of the results and for consistent speed of testing.

  • Tensile Strength
  • Yield Strength
  • % Reduction of Area
  • % Elongation
  • Charpy and DIN Impact Testing (Test temperatures range from -320 ºF to +110 ºF to ASTM “V” and “U” notch to Japan-European “V” and “U” notch Specifications)
  • Welder Qualifications and Evaluation
  • Image Analysis


The mechanical analysis of a metal depends on the precision that the samples are machined. Because tensile test samples are either round or flat in geometry, proper machining preparation is an essential step in a quality program of mechanical testing. To assure that the proper dimensions and surface finish is in strict conformance to ASTM E-8 and A-370 procedures, the round sample specimens are machined on the computer numerical control (CNC) turning center. The flat sample specimens are machined on a horizontal machining center.

Charpy “V” notch impact specimens are rough machined and surfaced ground to proper dimensions. The “V” groove is machined on a precision broaching machine to insure the proper depth and contour of the groove.

Hardness Testing to ASTM E-10 and E-18

Routine hardness testing is accomplished with Brinell and Rockwell instruments with ease and accuracy. Brinell hardness measurements are made using a computer controlled optical scanner to provide extremely accurate and repeatable readings. To accommodate micro and macro hardness testing, the Knoop and Vickers instruments will handle those specialized tests with accurate and repeatable results.
