Overview

4B drop forged chain is made of special heat treated alloy steel case hardened to Rockwell C57 with a ductile core hardness of Rockwell C40. Heat treating is a complex process that is done to provide the optimum chain link with a more fracture resilient ductile core for shock resistance and an extremely hard exterior surface for superior wear resistance. 4B drop forged chain is backed by an international network of companies with over 120 years of experience, and a global team of engineers that can provide you with practical solutions for all your material handling applications.
