Creep & Stress Rupture Testing - Nuclear Sector

Creep & Stress Rupture Testing Services for the Nuclear Industry

Creep and rupture tests are utilised to evaluate and predict the time-dependent behaviour of materials at elevated temperatures under applied stress in tensile or compression. Deformation is measured as a function of time.

Understanding material properties is essential for designing nuclear safety-related components and systems used during processing, transport, and storage.


We can use this data to:

  • Develop advanced materials that are fit for purpose
  • Develop operating limits for existing materials in new environments
  • Predict how joining techniques will perform under real-life conditions
  • Estimate service life
  • Develop maintenance schedules and reduce the risk of catastrophic failures of equipment under high-temperature and stress conditions


Lucideon has 22 creep / stress rupture test stands available, that can test specimens up to 10-1/8" in length ranging from carbon steel alloys and stainless steels to Inconel alloys. Tests may be conducted up to 1650°F in temperature and 10,000 lbs in load. Temperature and creep readings are recorded and monitored continuously to ensure accuracy of results.
