ASTM A 1106/A1106M : 2017

1.1This specification2 covers austenitic high-manganese alloy steel plates produced by hot rolling and controlled cooling. The plates are intended primarily for use in welded pressure vessels.

1.2Due to the inherent characteristics of the rolling and cooling processes, or both, the plates shall not be formed at temperatures exceeding 932°F [500°C].

1.3The maximum thickness of plates is limited only by the capacity of the material to meet the specified mechanical property requirements; however, current mill practice normally limits this material to 2.5 in. [63.5 mm] max.

1.4The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.5This 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.
