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.

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