The Creep Rupture Properties of ASME SA 516 (Grade 55) Steel in the Range 426°C to 872°C

The in-air creep-rupture properties of SA-516 (Grade 55) steel have been investigated in the temperature range 426–872°C (800–1600°F). The rupture time and creep rate data have been correlated using the Larson-Miller method, and relationships have been developed between the time to onset of tertiary...

Description
Summary:The in-air creep-rupture properties of SA-516 (Grade 55) steel have been investigated in the temperature range 426–872°C (800–1600°F). The rupture time and creep rate data have been correlated using the Larson-Miller method, and relationships have been developed between the time to onset of tertiary creep and the time to rupture. Interpretation of the data involved consideration of the microstructural changes above and below the eutectoid temperature, and in which decarburization was an important factor.
