C55 is a medium carbon steel that is widely used in applications where enhanced strength and hardness are required. This material is particularly chosen when these characteristics are critical, exceeding what can be achieved in its “as-rolled” condition. Its medium carbon content allows it to be easily heat-treated, further enhancing its mechanical properties.

One of the key advantages of C55 steel is its exceptional dimensional accuracy, including precise size tolerances, straightness, and concentricity. These attributes are particularly beneficial in high-speed applications where reliability and durability are crucial.
