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
24、ature is conditioned by the MoS2lubricant. 3) Published as ASD Prestandard at the date of publication of this standard. 4) Published as ASD Technical Report at the date of publication of this standard.
