Chrome steel balls are made from AISI 52100 Chrome steel. Uniformly hardened and tempered all the way through the ball to achieve maximum strength and quality. Ball hardness is controlled within the 60-67 HRC range as measured on parallel flat surfaces. Ball grades are defined numerically 3 - 2000 (3 being highest quality, 2000 is the lowest) Chrome steel balls are attracted to magnets. GRADES Grade Diameter Tolerance Per Ball Sphericity

Industry Standard Grade 100 Hardened Steel Ball Bearings: High Quality Graded Hardened Chrome Steel Ball bearings made from Chromium AISI 52100 steel. Hardened to 60-67 Rockwell Scale equivalent to 700-900 HV (Vickers Scale) and are hardened all the way through the ball. These are the same hardened steel balls used to manufacture bearing assemblies and have a high duty and life cycle. Manufactured in compliance to the following international standards: AISI52100 / EN31 / BS534A99 / W1.3505 / BS535A99 / UNI100C6 / AFN100C6 / DIN100C6 / JIS G4805 SUJ2
