1.2 Use of water quenching is prohibited for any ferritic grade when heat treatment is performed after heading or threading.


1.3 Except as permitted below for B6X; bolting material that is subsequently cold drawn for dimensional control shall be stress-relieved after cold drawing. The minimum stress-relief temperature shall be within not more than 100 °F [55 °C] below the tempering temperature. Tests for mechanical prop-erties shall be performed after stress relieving.


1.4 B6 and B6X shall be held at the tempering tempera-ture for a minimum time of 1 h. B6X bolting material may be furnished in the as-rolled-and-tempered condition. Cold work-ing after heat treatment is permitted for B6X material provided the final hardness meets the requirements of Tables 2 and 3.


1.5 B7 and B7M shall be heat treated by quenching in a liquid medium and tempering. For B7M bolting components, such as bolts, studs, or screws, the final heat treatment, which may be the tempering operation if conducted at 1150 °F [620 °C] minimum, shall be done after all machining and forming operations, including thread rolling and any type of cutting. Surface preparation for hardness testing, nondestructive evaluation, or ultrasonic bolt tensioning is permitted.


1.5.1 Unless otherwise specified, bolting material for Grade B7 may be heat treated by the Furnace, the Induction or the Electrical Resistance method.


NOTE 4—Stress-relaxation properties may vary from heat lot to heat lot or these properties may vary from one heat-treating method to another. The purchaser may specify Supplementary Requirement S8, when stress-relaxation testing is desired.


1.6 Bolting material Grade B16 shall be heated to a temperature range from 1700 to 1750 °F [925 to 955 °C] and oil quenched. The minimum tempering temperature shall be as specified
