New Carpenter Alloy Combines High Strength and Toughness
03/15/2011 - Carpenter Technology introduces Temper Tough™ alloy, a new ultra high-strength steel alloy that is a lower cost alternative to many cobalt-containing precipitation hardenable alloys.
Carpenter Technology Corp. has developed Temper Tough™ alloy, a 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 quenched and tempered alloy that has a unique combination of high strength and high toughness. The new alloy’s combination of high strength and toughness may allow designers and engineers to achieve an extended cycle life where components are under high loads with the continual stress of intense, repetitive motion.
Readily available, the new alloy is suitable 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 ksi√in. Temper Tough has also demonstrated superior fatigue resistance properties (axial-axial) of 120 ksi (827 MPa) compared to traditional quenched-and-temper alloy steels averaging 79 to 85 ksi (545 to 586 MPa).
Temper Tough’s attributes make it a candidate for applications in high-demand crank cases, drive trains, power trains, structural members, suspensions, and industrial tooling. It is particularly appropriate 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.
Carpenter Technology Corp., based in Wyomissing, Pa., is a leading manufacturer and distributor of conventional and powder metal specialty alloys, including stainless steels, titanium alloys, tool steels and superalloys.
