摘要：A study on the low hardness problem of P91 steel was conducted in this paper by a variety of analytical testing methods, including hardness testing, chemical composition analysis, metallographic examination and mechanical properties testing. A significant discrepancy was revealed between the hardness HBHLD, which is converted from Leeb hardness, and Brinell hardness HB. The intrinsic correlation between hardness and metallographic microstructure and mechanical properties was then established. At last, we have concluded the safety performance assessment strategies of P91 steel based on Leeb hardness testing results.
