Air Melt Cast Alloys

Miller Castings works with many different air melt steel alloys. The most common alloys used in our air melt casting operations are 347 S.S. & 17-4PH. Fifty percent of the alloys we pour at Miller are Carbon and Low Alloy steels, Cobalt, almost all of the 300 & 400 series Stainless Steels and Precipitation Hardening alloys.

Miller uses the SPAL (Surface Protection Air Liquid) process for all air melt casting operations.
