Creep rupture testing involves applying a constant stress load to a specimen at a specified temperature until failure. The temperature of this test can reach up to 1200 °C or 2192 °F. Typically, metal specimens begin to show signs of creeping around one-third of their melting temperature, but the test continues until the specimen ruptures. Our experts analyze data points taken throughout the process to evaluate the material’s time-to-failure performance. The amount of creep or deformation that occurred is also measured and evaluated to calculate how that material could change while in service.
