QuesTek® Innovations Ferrium® M54™ Ultrahigh-strength Steel for Structural Applications
Categories: Metal; Ferrous Metal; Alloy Steel

Material Notes: Description: Ferrium® M54™ is an ultra high-strength steel for structural applications. Ferrium® M54™ was designed to provide mechanical properties equal to, or better than ultrahigh-strength steels such as Aermet® 100. Ferrium® M54™ has high resistance to stress-corrosion cracking (SCC) over conventional ultra highstrength steels. Ferrium® M54™ utilizes an efficient M2C strengthening dispersion precipitated through tempering while avoiding other carbides. This maximizes strength, wear resistance, and toughness; resulting in a unique combination of mechanical properties. Ferrium® M54™ has high hardenability, permitting less severe quench conditions for a given section size and resulting in less distortion during heat treatment. M54™ should be considered for use in applications requiring high strength with high fracture toughness, and good resistance to stress corrosion cracking (per ASTM F1624). M54™ is supplied in a normalized and annealed condition.

Typical Application: Aircraft landing gears, arresting tailhooks, blast-resistant or impact containment devices, armor, flap tracks, actuator, drive shafts, sporting goods, fasteners and other structural applications.

Application Environment: Ferrium® M54™ is not considered corrosion resistant. Therefore, users should consider the specific environment when determining surface treatment.

Fording: Forge at 2000°F (1093°C) followed by air cool, normalize, subzero treatment and anneal.
Machinability: Annealed Ferrium® M54™ has machinability similar to AMS6532.

Heat Treatment:
Solution Treatment: 1940°F(1060°C) 60-90 minutes and oil quench or equivalent, water quenching is not recommended. Soak time must be closely monitored, load couples are recommended..
Sub Zero Treatment: Following the solution treatment, -100°F(-73°C) 1-3 hours and air warm.
Temper: At 975°F (524°C), 6 hours and air cool.

Product Forms: Ferrium® M54™ may be manufactured in typical ingot, bar, and billet forms. Sheet and plate also available upon request.

Ferrium is designed by Questek Innovations, LLC. and is manufactured by Latrobe Specialty Steel under license.
