CarTech® Ferrium® C61™ Alloy

UNS K93061 | U.S. Patent No 6,176,946 B1; 6,464,801; 6,485,582; 6,635,126
Composition (Nominal):
0.15 C, 3.50 Cr, 9.50 Ni, 18.00 Co, 1.10 Mo, 0.08 V, Bal. Fe

A premium quality carburizing steel that offers high core strength, high fatigue strength, high temperature resistance and high hardenability.

The alloy has achieved carburized case hardness of 60-62 HRC but provides ultra-high core properties for demanding shaft and gear applications. The high tempering temperature (900°F) offers a 400-600°F increase in thermal stability relative to conventional gear steels. It is well suited to low-pressure carburization at high temperature to reduce manufacturing time and expense while providing reliable carburization profiles. The material does not require a separate hardening/quenching process.

Typical applications include power transmission shafts, gears and other demanding applications in aerospace, energy, and racing/off-road/mission-critical vehicles and other industries where weight savings, compactness, high temperature resistance and high surface fatigue resistance are valued. The high core strength and high hardenability particularly benefit structural components such as shafts with integral gearing.

Specifications: AMS 6517, D210-13802-1
