Automotive, Truck, and Railcar - Alloys for Automotive, Truck, and Railcar

The automotive industry uses a wide variety of specialty metals. Each has their own special properties making them the materials of choice for exhaust system parts, gaskets, air bag inflator housings, windshield wipers and blades, fuel systems, and, fasteners, along with many other critical components. In addition to powertrain and structural parts, austenitic stainless steels are used by the trucking industry for tanks for food and dairy containment, cryogenic applications, chemicals, and acids. Stainless is also used on exterior trim for its bright appearance and for internal components for its corrosion resistance. Temper-rolled Types 301 and 201 are commonly used to for mass transit rail cars, with specialty alloys employed for transport of corrosive chemicals.
Product Line Description Alloys
Nickel Alloy 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. AL 600™

Stainless Steel 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, truck and rail market applications. Rail cars are fabricated from specialty steels for reduced weight, and for resistance to corrosive products such as acids and caustic chemicals. AL 201HP™
