Study of Steel P92 Microstructure and Mechanical Properties after Different Heat Treatment Regimes

  • Published:
Metal Science and Heat Treatment Aims and scope

The effect of normalizing in the temperature range 950 – 1150°C with subsequent tempering for 2 h at 760°C on the microstructure of Cr – Mo steel P92 is studied by optical and electron microscopy. The interconnection between steel microstructure and mechanical properties is considered. Normalizing at 1040°C is shown to be advantageous for forming a fine-grained structure containing tempered martensite and strengthening inclusions with favorable morphology and composition.
