HISTORICAL
MAM2300A
This specification covers steel cleanliness requirements for premium aircraft-quality ferromagnetic steels by magnetic particle inspection methods, measured in metric (SI) units. Primarily applicable to blooms, billets, tube rounds, stock for forging or flash welded rings, slabs, bars, plate, tubing, and extrusions used in fabricating highly-stressed parts where very strict magnetic particle inspection standards are used in final inspection of such parts.

MAM2301B
This specification covers steel cleanliness requirements in SI (metric) units for aircraft-quality ferro-megnetic steels, other than hardenable corrosion-resistant steels, by magnetic particle inspection methods. AMS 2301 is the inch/pound version of this MAM. This procedure has been used typically for the cleanliness evaluation of blooms, billets, tube rounds, stock for forging or flash welded rings, slabs, bars, sheet, strip, plate, tubing, and extrusions used in fabricating parts subject to magnetic particle inspection, but may be used for qualification of a heat, melt, or lot of steel.
