4B now manufacturing Manganese Wear Rails for Forged Chains

The manganese wear rails are available from stock as

- 50mm x 10mm ‘V'' Groove.

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.
