SUMMARY
The discussion centers on finding a complete chart of ASTM grain size numbers, particularly in relation to a sample with a grain size number of 19.5, which exceeds the highest value of 14.3 listed in ASTM E112. Participants mention the linear intercept method as a common technique for determining grain size and reference a resource at metallography.com for additional information. The inquiry highlights the need for comprehensive resources on ASTM grain size standards.
