Ferrium M54 is an ultra high-strength steel for structural aerospace and other applications where 300M, 4340, and AMS 6532 are typically used. 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.

Applications:
Typical applications can include aircraft landing gears, arresting tailhooks, blast-resistant or impact containment devices, armor, flap tracks, actuators, drive shafts, load bearing shafts for oil and gas, sporting goods, fasteners and other structural applications.
