MIL-C-24689B
COBALT ALLOY CASTINGS, WEAR AND CORROSION RESISTANT
Organization:
NAVY - SH - Naval Sea Systems Command (Ship Systems)
Year: 1992
Abstract: This specification covers castings of cobalt-chromium-tungsten and cobalt-chromium-nickel alloys for use where corrosion and wear resistant materials are required.
Castings are of the following compositions, as specified (see 6.2).
(a) Composition No. 20 (UNS R30006).
(b) Composition No. 21.
(c) Composition No. 22 (UNS R30001).
(d) Composition No. 23 (UNS R30021). Intended Use: These castings, with high abrasion resistance, excellent corrosion resistance, and high hardness, are intended for use as bearings, valve discs, bushings, and seals, operating under high loads with little or no lubrication. Alloy R30001 has higher abrasion resistance than alloy R30006, but with lower impact strength.
