This rating chart supplements ASTM Specification A247, and is used to determine graphite form, size and distribution, for both gray and ductile iron. You will find this chart a valuable addition to the metallurgy lab to meet the requirements of ASTM A247.
The chart uses actual, high-quality photomicrographs as opposed to artist renditions. It represents the following categories:
- distribution examples,
- graphite forms,
- flake size class,
- and nodule size class.
The chart was prepared by the AFS Cast Iron Division Quality Control Committee with the approval of the ASTM Committee on Iron Castings.
Dimensions: 40 x 28 in.
