Carpenter Technology says its PremoMet alloy’s strength, toughness and fatigue resistance makes it a viable alternative to many cobalt-containing steel alloys. The alloy is suited for power train components in diesel engines and other commercial transportation and locomotive applications.
 
Strength and fracture toughness properties lighten part weight for high-load applications, the company says. 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 higher than lower-strength alternatives, the company says. Lighter-weight components can reduce stress on other parts, which provides energy consumption throughout a product’s lifecycle, the company says.
 
The alloy is available in bar, hollow bar, wire, strip, plate and billet forms and can be plated.
