Description / Abstract:
Purpose:
This specification covers steel cleanliness requirements in
metric SI units for special aircraft-quality ferromagnetic steels,
other than hardenable corrosion resistant steels, by magnetic
particle inspection methods.
AMS 2304 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.
Product qualified to this specification is not recommended for
use in parts where the high transverse properties of
vacuum-arc-remelted or electroslag remelted steels are required
(See 8.2).
