Abstract

The experimental data on the as-received (AR) Type 316H stainless steel at 550 °C have shown that creep crack growth (CCG) trends in long term tests are generally higher than those of short term tests and the CCG behaviour in these tests may be estimated in much shorter time scales by performing tests on pre-compressed (PC) material. In this paper, the predicted uniaxial creep trends for the AR material have been compared to the existing data on PC material and it has been found that for this material and conditions the uniaxial creep trends may be predicted by performing accelerated tests on PC material. The developed uniaxial creep trends for AR and PC materials have been implemented in finite element (FE) simulations to predict the long term CCG behaviour of 316H at 550 °C. The numerical predictions have been validated through comparison to the available experimental data.
