    • Abstract
  • For the aim of dealing with the improper repairmen and replacement induced by inaccurate hardness measurement of the P92 components, the samples with various harnesses were prepared under the different heat treatment processing conditions for P92 base metal and then tested under the Leeb hardness and Brinell hardness approaches, respectively. Thus, the relationship between Leeb hardness and Brinell hardness of base metal and welded metal of P92 steel was obtained. The results revealed that for P92 base metal and welded metal, the direct Brinell hardness form the portable Brinell hardness equipment was higher than the actual Brinell hardness. In addition, the constructed relationship between the Leeb hardness and Brinell hardness could measure the accurate Brinell hardness of the in-service P92 components.
