Testing

Metallurgical testing and analysis can be a valuable source of information to any industry working with metals.

Various tests are necessary to detect surface and internal flaws, determine microstructural features, evaluate heat treatments and assure conformity to required specifications.

  • Tensile test at room temperature
  • Tensile test at hot temperatures up to 900°C
  • Charpy test at temperatures from -196°C to +150°C
  • PWHT
  • Step cooling test
  • Bend test
  • Stress rupture / creep test
  • Micrographic examination
  • Microstructure examination for intermetallic phases
    and precipitates checking
  • Inclusion content
