Communication: Ferrite Number as a Function of the Larson-Miller Parameter for Austenitic Stainless Weld Metals after Creep Testing

Five different stress levels between 70 and 240 MPa were used together with a range of temperature (550 deg C to 700 deg C) for creep testing on E308H and E316H austenitic stainless steel weld deposits. The test results show that the Ferrite Number (FN) exhibits a linear relationship with the Larson...

Description
Summary:Five different stress levels between 70 and 240 MPa were used together with a range of temperature (550 deg C to 700 deg C) for creep testing on E308H and E316H austenitic stainless steel weld deposits. The test results show that the Ferrite Number (FN) exhibits a linear relationship with the Larson-Miller parameter (LMP) after creep testing. More sigma phase formed in commercial E316H weld deposits than in commercial E308H because of the difference in molybdenum content.
