Notes:
* ASTM A27 Class 1 requiring post-weld heat treatment on all welds is standard from AMERICAN CENTRIFUGAL. Class 2, which does not require post-weld heat treatment of welds, is not available.
** Impacts (Ft.-Lbs.) to be mutually agreed upon.
+See specification for maximum Brinell hardness after final heat treatment.
The latest revision of a specification shall take precedence in which case the chemical composition may vary from that shown above.
See the Annual Book of ASTM Standards, Section 1, Volume 01.01 and 01.02 for complete details of the specifications.
AMERICAN also produces material to other ASTM specifications such as A356.
