Steel C55 is suitable for higher strained parts in vehicle, engine and transmission manufacturing that require an enhanced wear resistance. Preferred application for parts undergoing a surface hardening lower risk of tearing for larger and complexer parts than C60 (e.g. transmission gear wheels, shafts, indented rollers). Lowest appplication temp. -25 °C.
