Ultra High-Strength Steel Alloy

Carpenter Technology Corp.'s new ultra high-strength steel (UHSS) alloy that is a lower costalternative to many cobalt-containing precipitation hardenable alloys. TemperTough alloy is an air-melted, cobalt-free quench and tempered alloy that has aunique combination of high strength and high toughness attributes that may allowdesigners and engineers to achieve an extended cycle life where components areunder high loads with constant stress of intense, repetitive motion.

This alloy is a lower cost alternative to cobalt-containingprecipitation hardenable alloys for a variety of general purpose tooling,industrial and automotive applications, especially those in which designers maybe seeking to lighten the weight and increase the longevity of their products. TemperTough alloy is able to attain both a typical strength of 290 ksi ultimatetensile strength (UTS) and a typical range of toughness between 60 and 65 ksia^sin. Temper Toughhas also demonstrated fatigue resistance properties (axial-axial) of 120 ksi(827 MPa) compared to traditional quench-and-temper alloy steels averaging79-85 ksi (545-586 MPa).

The attributes of Temper Tough alloy make it useful for applications inhigh-demand crank cases, drive trains, power trains, structural members,suspensions and industrial tooling.
