First new CCW is sold by weight not sieve size. CCW14 is approximately .0139” and larger as a test sieve size. Cast Steel is sold by sieve size and the size designation (S-110) is the approximate size in inches. CS S-110 has 90% of the particles larger than .0117” and can have no more than 50% of the particles larger than .0139”; typically 20% larger. So if you refer to Table 1, Size requirements of in-process media, in AMS2430, these different media must be maintained in a peen process using the requirements. S-110 vs. CCW 14. This attachment is not a cross reference guide. So your assumptions on the sizes show above CS vs. CCW is correct they are approximately the same size but do not just change without re-running your saturation curves.
