Nitro® sprockets are manufactured from 1045 cold drawn carbon steel. Many competitors use lower grade steels such as 1018, 1025 or even powdered metal.
Bores are finished with a keyway & 2 setscrews.
Black Oxide Finish
After all phases of sprocket manufacturing are completed, the sprockets are finished with a black oxide to protect against corrosion.
