The Evaluation of Actual Material Properties of Low Alloy CrMoV Steel from the Results of Small Punch Tests
The Small Punch (SP) test technique is used for the evaluation of actual tensile, fracture and creep characteristics of materials exposed for a long period in operating plant components in order to provide data needed for plant life and integrity assessment.
In the present paper the results of SP tests in the temperature range from -193 °C to +20 °C, carried out in two laboratories on low alloy steel of type 14MoV6-3 in as received state and after long term operation at 540 °C were compared. SP transition temperatures TSP determined from the temperature dependences of the fracture energy were correlated with the FATT temperatures obtained using standardized Charpy V notch test specimens.
