ISO 683-3 Grade 16MnCrB5 normalized or normalized formed (+N)

ISO 683-3 Grade 16MnCrB5 normalized or normalized formed (+N) introduction

Steel 16MnCrB5 is suitable for parts in vehicle manufacturing and machine engineering, that are predominantly wear loaded and that should have a very favorable ductility behaviour in case-hardened condition (e.g. piston pins, camshafts).

Equivalent material: GB 15CrMnBH, GB A25155, EN 1.7160, GB 15CrMnBAH, GB A25157, DIN 1.7160
