Mechanical Properties
Chrome steel balls are uniformly hardened and tempered throughout their entire diameter to achieve maximum strength and quality. Ball hardness is controlled within the 60-66 HRC range as measured on parallel flat surfaces. Custom heat treating is available for special hardness and dimensional stability requirements.
