Turbochargers operate at the absolute limit of material science, with rotational speeds exceeding 200,000 RPM and temperatures that can melt standard steels. Carpenter Technology provides the nickel-base superalloys and heat-resistant stainless steels required to ensure turbocharger efficiency and longevity—helping OEMs meet tightening emission standards and performance demands.

Superalloys engineered for the extreme exhaust gas temperatures of gasoline engines.
Materials with superior creep resistance to maintain housing and wheel tolerances.
Consistent material quality and pricing to support high-volume global turbo platforms.
Alloys designed to survive the rapid expansion and contraction of thousands of cold-start and high-load cycles.
Specialized chemistries that prevent the formation of scale and surface degradation in the exhaust stream.
Heat-resistant bolting solutions that maintain clamp load despite continuous exposure to glowing-hot temperatures.
Right-sized product forms and consistent microstructures that improve the machinability of complex turbo housings and wheels.

Maintains dimensional stability under extreme centrifugal force and heat, preventing wheel-to-housing contact.
The ability to maintain mechanical strength even when components are operating at a dull red heat.
Formulated to withstand the corrosive byproducts found in modern EGR (Exhaust Gas Recirculation) systems.
Ensures that every part in a high-volume run achieves the exact hardness and fatigue life required.
We combine over a century of high-temperature metallurgy with advanced processing to solve the industry’s most difficult forced-induction challenges.
Rotating at incredible speeds, the turbine wheel must survive high-velocity exhaust pulses and extreme heat. Our nickel-base superalloys provide the creep-rupture strength required for 200,000+ RPM.
Exceptionally high yield and creep-rupture properties; a standard for high-speed rotors.
Premier high-temperature alloy for the most severely stressed turbine components.
Excellent resistance to high-temperature corrosion and oxidation in exhaust streams.
Standard fasteners often loosen or fail when exposed to the heat of a turbocharger housing. Our alloys maintain their "spring" and clamp load even at 1300°F and above.
Cost-effective iron-base superalloy with notched rupture strength superior to alloy steels.
Lower-nickel variant providing consistent heat resistance with optimized material costs.
High fatigue resistance and oxidation resistance for critical high-temperature bolting.
Wastegate valves and housings face the brunt of the exhaust heat. Our materials prevent warping and ensure the bypass valve continues to seal perfectly over the life of the engine.
Excellent fatigue strength and immunity to chloride stress-corrosion cracking.
High strength and corrosion resistance for structural turbo components.
