Carpenter Introduces New High Strength, High Toughness Alloy
03/25/2011 - Carpenter Technology unveils its newly-developed 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 unveiled its newly-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, an air-melted, cobalt-free quench-and-tempered alloy, 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 the continuous stress of intense, repetitive motion.
The new alloy is a lower-cost alternative to cobalt-containing precipitation hardenable alloys for a variety of general-purpose tooling, industrial and automotive applications. It is particularly appropriate in cases where designers seek to lighten the weight and increase the longevity of their products.
TEMPER TOUGH alloy is able to attain a typical strength of 290 ksi ultimate tensile strength (UTS) as well as a range of toughness between 60 and 65 ksi√in. The new alloy has also demonstrated superior 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 new alloy’s attributes make it a candidate for applications in high-demand crank cases, drivetrains, powertrains, structural members, suspensions, and industrial tooling, especially when designers are looking for affordable solutions to reduce weight without sacrificing performance.
Carpenter Technology currently offers TEMPER TOUGH alloy in bar product forms.
Carpenter Technology produces and distributes conventional and powder metal specialty alloys, including stainless steels, titanium alloys, tool steels and superalloys. The company has experienced technical service engineers and technicians, metallurgists and market specialists who are available to assist its customers with material development selection, specifications, properties and fabrication characteristics.
