What's New: Alloy Solution for Heavy Duty Power Train Components
Introducing PremoMetTM Alloy
Carpenter's new PremoMet alloy offers superior strength, toughness and fatigue resistance and may be considered as a lower-cost alternative to many cobalt-containing steel alloys. It may allow design engineers to lighten the weight of parts for high-load applications by as much as 25 percent while also extending the life of the product.
Consider PremoMet alloy for high-demand power train components in heavy-duty diesel engines and other commercial ground transportation including locomotive.
- Ultra-high strength
- Superior fracture toughness
- Superior durability, even in high-load applications
- Up to 25% reduction in weight of part
- 500°F (260°C) temper facilitates plating
