Creep-Rupture Properties and Life Evaluation of Low Hardness Modified 9Cr-1Mo Steel

Abstract:

Creep-rupture properties of modified 9Cr-1Mo steel with 140~150HB low hardness were studied. Results showed that the creep-rupture properties of the experimental steel deteriorate badly and decreased with experimental temperature increasing. The life evaluation was carried out based on the experimental results, that provides guidance for material evaluation and operation supervision.
