Ultra High-Strength Steel Alloy

Carpenter Technology Corp.'s new ultra high-strength steel (UHSS) alloy that is a lower cost alternative to many cobalt-containing precipitation hardenable alloys. Temper Tough alloy is an air-melted, cobalt-free quench and tempered alloy that has a unique combination of high strength and high toughness attributes that may allow designers and engineers to achieve an extended cycle life where components are under high loads with constant stress of intense, repetitive motion.

This alloy is a lower cost alternative to cobalt-containing precipitation hardenable alloys for a variety of general purpose tooling, industrial and automotive applications, especially those in which designers may be seeking to lighten the weight and increase the longevity of their products. Temper Tough alloy is able to attain both a typical strength of 290 ksi ultimate tensile strength (UTS) and a typical range of toughness between 60 and 65 ksia^sin. Temper Tough has also demonstrated fatigue resistance properties (axial-axial) of 120 ksi (827 MPa) compared to traditional quench-and-temper alloy steels averaging 79-85 ksi (545-586 MPa).

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