Keys: Stainless steel or Nickel alloy treated for HV 600. 1) Corresponds to the minimum tensile stress which the insert is able to

23、 withstand at ambient temperature without breaking or craking when tested with a bolt of a higher strength class. 2) Maximum temperature that the insert is able to withstand, without permanent alteration to its original characteristics, after ambient temperature has been restored. The maximum temper
