JBK-75 microstructure specification recommendation
Description
Since the ASTM-E-45 standard for microcleanliness is not applicable to superalloys like JBK-75 stainless steel (Modified A-286), Rocky Flats should adopt the Ladish microcleanliness standard (APML Cleanliness Classification of High Temperature Alloys Chart, 1971), as a guide for setting material acceptance specifications for JBK-75. Inclusion ratings of S-2, N-2, C-2, and M-2 should be acceptable. The microstructure should have a grain size of 5 or finer, but not smaller than 9, and microsegregation (banding) should be kept to a minimum
