Description / Abstract:
Purpose:
This specification covers steel cleanliness requirements in SI
(Metric) units for aircraft-quality, ferro-magnetic, hardenable,
corrosion-resistant steels as determined by magnetic particle
inspection methods. This specification contains sampling, specimen
preparation, and inspection procedures and cleanliness rating
criteria.
AMS 2303 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, 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.
