摘要：

Analyzed theoretically the reasons for the formation of massive ferrite through analysis of the phase diagram of P91 steel. By Combining with the heat treatment of the header, we can make a conclusion that the formation of massive ferrite in P91 steel is because temperature is too high (more than the A1 transformation point). And the process of elimination of massive ferrite was proposed.
