Carpenter Technology Corp. developed a new ultrahigh-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.

The attributes of TEMPER TOUGH alloy make it a candidate for applications in high-demand crankcases, drivetrains, powertrains, structural members, suspensions and industrial tooling, especially when designers are looking for affordable solutions to reduce the weight of parts and/or components without sacrificing performance. Carpenter Technology currently offers TEMPER TOUGH alloy in bar product forms.
