Metallus Inc.
A maker of specialty alloy steels used in demanding parts like gears, crankshafts and axles for cars, trucks and aircraft, Metallus grew out of a steel mill that bearing maker Timken opened in 1915 to keep its own supply reliable during World War I. Spun off as TimkenSteel in 2014, the Ohio company renamed itself Metallus in 2024 — a blend of "metallurgy" and the Latin word for "quality," ending in "us" as a nod to teamwork.
