The information fed back from power plants shows that the hardness of fastening bolts is often beyond standard set for steam turbines.Regarding to this
the fabricating process and quality inspection for bolts have been analysed.Directing against the lower bolt hardness resulted from mechanical fabrication process
and the phenomenon of bolt hardness beyond set standard caused by unproper heat treatment technology
as well as problem of bolt hardness beyond set standard due to different detection methods
corresponding solving methods have been put forward.
