A central tenet of the standard is that hard microstructures (like martensite) are significantly more susceptible to hydrogen embrittlement. To mitigate this risk, the standard mandates strict hardness limits:
: Provides specific guidance in Appendix D on the correct application of PWHT, including heating/cooling rates and measurement positions, to ensure residual stresses are properly relieved. Process Coverage
