This specification covers steel cleanliness requirements in metric (SI) units for premium aircraftquality ferromagnetic steels@ other than hardenable@ corrosion-resistant steels@ by magnetic particle inspection methods. AMS 2300 is the inch/pound version of this MAM. Application: 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@ 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@ but may be used for qualification of a heat@ melt or lot of steel.
