Product brief introduction

It has high strength, hardness, abrasion resistance and good toughness. Its hardenability is slightly higher than 40Cr, and its critical quenched diameter in oil is 18 to 33mm. After normalizing, it has good machinability, cold drawing and rolling. Wire, tapping and forging, heat treatment process performance are also good
