1.1 This practice establishes the controls required for hot rolling mill solution heat treatment of the 6xxx series aluminum alloy plate in when ASTM material specifications allow use of this process in lieu of furnace solution heat treatment. For the alloys listed in , this practice is an alternate process to solution heat treatment in a furnace, such as specified in Practice B 918 as the preliminary step for the attainment of T651-type tempers (see ANSI H35.1).
1.2 This practice applies only to hot rolling mill solution heat treatment of plate for the listed aluminum alloys. Precipitation hardening (aging) processing and equipment calibration for aging shall meet the practice and requirements of Practice B 918.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
