Drop Forged Conveyor Chain

           
 

4B is a manufacturer of drop forged chain for agricultural and industrial applications.  4B’s drop forged chain is made of special heat treated alloy steel case hardened to Rockwell C57 - C62 with a ductile core hardness of Rockwell C40.

4B’s superior heat treatment technique provides the optimum chain link with a more resilient ductile core for shock resistance, and an extremely hard exterior surface for superior wear resistance.

4B’s drop forged chain is backed by an international network of companies with over 125 years of experience, and a global team of engineers and sales professionals that can provide you with practical solutions for all your material handling applications.
