STUDY ON PERFORMANCE OF HIGH HARDNESS AND LOW HARDNESS WELD JOINTS ON P91 MAIN STEAM PIPE
and persistent strength of high and low hardness weld joints on P91 steel has been carried out
the results show that: the R weld joint with higher hardness and lower toughness has the higher persistent strength;the D weld joint with lower hardness and higher toughness has lower persistent strength.The persistent strength of material is closely related to the creep life of component.
