SPC and creep tests of type F modified chromium steel

Original language description

Small punch creep test (SPC) is an alternative method for obtaining information about the material properties of steels and alloys when only a limited amount of test material is available that does not make it possible to perform conventional creep and/or stress rupture tests. SPC testing can also be used for determination of the residual life of critical components of a fossil fuelled power plant. SPC method is a part of the CWA 15627 "Small Punch Test Method for Metallic Materials" published in 2007 and this method will be a part of a prepared proposal of a standard of Small Punch Testing. Similar activities are also within ASTM (ASTM WK47431 “New Practice for Small Punch Test Method for Metallic Materials”), and in Japan they have an approved SPC test standard. Although the complex stress state of the SPC tests differs considerably from the uniaxial tension in case of creep test and further changes during the test, it was shown that the same stress-temperature dependence and relationships are valid in SPC tests as in creep tests, and by using a simple load-based conversion factor between the SPC test and the creep test with the same time to rupture, the results of both test types can be integrated. This is demonstrated by an example of modified chromium steel of F-type where a comparison of creep and SPC tests results was presented, as well as the conversion factor that allows comparison of these two methods.
