Ferrium® M54® Alloy

UNS K91973 | U.S. Patent Number 9,051,635 B2

Composition (Nominal):
0.30 C, 1.0 Cr., 10.0 Ni, 7.0 Co, 2.0 Mo, 1.3 W, 0.10 V

Ferrium M54 is an ultra high-strength steel for structural aerospace and other applications where 300M, 4340, and AMS 6532 are typically used. It is double-vacuum VIM/VAR processed by vacuum induction melting followed by vacuum arc remelting to provide optimum metallurgical quality and repeatability.

Ferrium M54 has mechanical properties equivalent to the previously mentioned conventional alloys, but with the added benefit of very high toughness. This can be a major benefit in applications requiring high impact resistance or in flaw-tolerant designs. In addition, Ferrium M54 has greatly improved resistance to stress-corrosion cracking (SCC) compared to conventional ultra high-strength steels. It also has high hardenability, permitting less severe quench conditions for a given section size and resulting in less distortion during heat treatment.

Specifications: AMS 6516
