Alloys for Automotive
For automobiles, nickel alloys, stainless steel and other ATI specialty materials are the choice for powertrain and structural parts, exhaust system and emission control parts, gaskets, air bag inflator housings, windshield wipers and blades, fuel systems, fasteners, hose clamps, gaskets and other components. ATI’s austenitic stainless steels are used by the trucking industry for tanks for food and dairy containment, cryogenic applications, chemicals, and acids. Stainless steel is also used on exterior trim for its bright appearance and for internal components for its corrosion resistance.
Forgings for Large Truck Components
ATI produces forgings for gears, crankshafts, connecting rods, axles and other large truck components. We make more than a half million transmission parts annually for six different types of trucks. We maintain an ISO/TS 16949:2009 certification to satisfy the requirements of automotive OEMs.
Railcars & Mass Transit
Railcars and mass transit vehicles are fabricated from specialty steels for reduced weight, and, in the case of railcars, resistance to corrosive products such as acids and caustic chemicals.
In high-performance Formula One auto racing, titanium alloys and nickel alloys are used for critical components throughout F1 cars. Our materials are used for front, rear and side impact structures, and the crash structures around the engine and gearbox. In addition, hubs, mounting bells, the steering rack, hydraulic cylinders, suspension pushrods, trackrods, assorted brackets, rod ends, and many small fixtures and fittings are made from ATI titanium alloys.
Nickel alloys are used when a high level of durability and performance are required. Common applications are for heavy-duty flexible connectors, tubular exhaust headers, high-temperature/high-strength fasteners, and turbocharger wheels.
Strength, corrosion resistance, oxidation resistance, formability, weldability, abrasion resistance and appearance are important consideration in the selection of stainless steels for many types of parts (stamped, drawn, welded) for automotive and commercial truck applications.
