Featured end-Market: Gears

Serving the Industrial Gear Market with Precision Materials

A.M. Castle & Co. is a trusted supplier of premium materials tailored to meet the demands of the industrial gear market. With a focus on both thru-hardened and carburized gear grades, A. M. Castle & Co. provides the steel necessary for high-performance gear applications like worm, bevel, helical, and spur gears.

Gear Grades for Every Application

Thru-Hardened Gear Grades
Thru-hardened steels, such as carbon steel 1045, alloy 4140, alloy 4150, and alloy 4340, are quenched and tempered to deliver consistent hardness and moderate wear resistance. These grades excel in applications requiring toughness, and they can also be surface-hardened through induction processes for even more robust performance. Typical applications include construction equipment and fuel pumps.

Carburized Gear Grades
Low-carbon steels like carbon steel 1018, alloy 8620, alloy 4820, alloy 4130 and alloy 9310 are carburized to achieve a tough, softer core with a hardened surface case. This creates superior wear resistance, ideal for gears in automotive differentials and heavy-duty transmissions.

Stainless Steel Options
For enhanced corrosion resistance and machinability, A. M. Castle & Co. offers grades like stainless 303, stainless 304, and stainless 316. These steels are perfect for spur, helical, and bevel gears in industries like printing, marine systems, and food processing.

Gear Types We Support

A. M. Castle & Co.’s materials power a variety of gear types:

Spur Gears: Common in transmissions and industrial equipment.
Helical Gears: Smooth, quiet operation for automotive and earth-moving machinery.
Bevel Gears: Essential for differential drives and hand drills.
Worm Gears: Enable precise motion control in musical instruments and automotive systems.

A. M. Castle is more than a supplier—we are a partner in precision engineering, ensuring your gears perform reliably in the toughest environments.
