Chemical Analysis

C=0,98-1,10%, Cr=1,4-1,65%, Mn=0,25-0,45%, Si=0,15-0,35%, S=max 0,025%, P=max 0,025%

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.
