Wyomissing, Pa. (December 3, 2009) – Carpenter Technology Corporation has announced the availability of Carpenter PremoMet™ alloy for consideration as a lower-cost alternative to many cobalt-containing steel alloys. With its superior strength, toughness and fatigue resistance, even in high-load applications, PremoMet alloy could be considered for many high-demand power train components in heavy-duty diesel engines and other commercial transportation and locomotive applications.
PremoMet alloy is a patent pending, ultra-high strength, high toughness, quenched and tempered alloy steel. Thanks to its advanced strength and fracture toughness properties, it may enable designers to lighten the weight of parts for high-load applications by as much as 25%. The weight reduction estimates are based on the attainable ultimate tensile strength of 2,040 MPa (296 ksi) combined with the fracture toughness which is much higher than the lower-strength alternatives. Refer to the table for technical comparisons with several alloy steels currently in use.
Lighter-weight components could result in a reduction of stress on other parts, meaning lower energy consumption throughout a product’s lifecycle.
PremoMet alloy is available exclusively from Carpenter in bar, hollow bar, wire, strip, plate and billet forms and can be plated.
