AIRCRAFT QUALITY STEEL CLEANLINESS Magnetic Particle Inspection Procedure AMS2301E

This specification covers steel cleanliness requirements for aircraft-quality ferromagnetic steels, other than hardenable corrosion-resistant steels, by magnetic particle inspection methods. Applicable primarily to blooms, billets, extrusions, tube rounds, heavy wall tubing, stock for forging and rings, tubing, bars, slab, and plate used in fabricating parts subject to magnetic particle inspection, but may be used for qualification of a heat, melt, or lot of steel.
