Ferrium® C64 is a premium quality carburizing steel that offers high core strength, high fatigue strength, high temperature resistance, and high hardenability versus AISI 9310, X53 (AMS 6308), EN36, and other standard carburizable alloys. Its benefits include light weighting of components and increasing power density in applications in aerospace, energy, racing/off-road/mission-critical vehicles, and other industries where weight savings, compactness, high temperature and surface fatigue resistance are valued.
Processed by vacuum induction melting followed by vacuum arc remelting, it can achieve carburized case hardness of 62-64 HRC, exceeding that of conventional gear steels while providing ultra-high core properties for highly-loaded components requiring wear and fatigue resistance.
The high tempering temperature (925°F/496°C) offers a 400-600°F (204-315°C) increase in thermal stability relative to conventional gear steels. Well suited to low-pressure carburization at high temperature to reduce manufacturing time and expense while providing reliable carburization profiles, Ferrium® C64 is direct gas quenched using moderate pressures which reduces the amount of distortion and eliminates the need for a separate hardening/quenching process.
