The committee agreed with the following assessment. The intention of the Heat Treat Section 8.0 was to make heat treating according to AMS 2772 the default method. There is an allowance in the ordering information of Section 4 to require heat treating according to ASTM B918, which if required would take precedence over AMS 2772. As the standard is currently written, it appears to be missing an item in the ordering information to specify that the hot rolling mill solution heat treatment method in ASTM B947 is unacceptable. ACTION: Becky Wyss will submit a limited scope ballot to revise B209 and B209M.
