UHSS alloy serves as alternative to many cobalt-containing, precipitation hardenable alloys

Carpenter Technology Corp. has developed a new ultrahigh-strength steel (UHSS) alloy that serves as an alternative to many cobalt-containing, precipitation hardenable alloys.

Temper Tough™ alloy is an air-melted, cobalt-free, quench-and-tempered alloy that combines high strength and toughness for components under high loads with constant stress of intense, repetitive motion. It is suitable for use in general-purpose tooling, industrial, and automotive applications, such as high-demand crank cases, drive trains, power trains, structural members, and suspensions.

The alloy is able to attain both a typical UTS of 290 KSI and a typical toughness between 60 and 65 KSI. It has demonstrated axial-axial fatigue resistance properties of 120 KSI.
