Forged Chains

4B's drop forged chain is made of special heat treated high grade alloy steel, case hardened to Rockwell C57-62 with a ductile core hardness of Rockwell C40.
4B's superior heat treatment technique provides the optimum forged chain link with a more resilient ductile core for shock resistance, and an extremely hard exterior surface for superior wear resistance. We offer a range of droped forged chains, pins & converyor chains. 

4B forged chain links and pins are also available in all grades of stainless steel.
