The influence of impurity content, tensile strength and grain size on in-service temper embrittlement of CrMoV steels

  • 1. Westinghouse Electric Corp., Orlando, FL (USA)

Description

The influence of impurity levels, tensile strength, and grain size on in- service temper embrittlement of CrMoV steels has been investigated. The samples for this study were taken from six stream turbine CrMoV rotors which had operated from 15 to 26 years. The effects of tensile strength and grain size on embrittlement susceptibility were separated by evaluating embrittlement behavior of two rotor forgings, which were made from the same ingot, after giving an extended step-cooling treatment. The results reveal that among the residual elements in the steels, only P produces a significant embrittlement
