Abstract
The paper is focused on summarizing the high temperature tensile, creep and stress relaxation small punch testing (SPT) of ferritic-martensitic steel P92. The relation of SPT results with conventional uniaxial tests results is presented. Two heats of P92 steel with different heat treatment are compared in SPT creep. The finite element modeling of SPT creep setup is compared with experimental SPT results. The stress relaxation SPT is discussed and values of initial stress and residual stress were evaluated from the test. Very good agreement of the stress relaxation SPT, stress relaxation uniaxial test and numerical modeling is shown by their comparison. An overview of the ongoing round robin on creep SPT is briefly outlined.
