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.
