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.
