Welded steel mill chains are recommended for most conveying, driving, and elevating applications where a high-strength steel rollerless chain is required. These chains will operate on the same sprockets as their cast chain counterparts.

WHX Series is available for many welded steel chains. WHX series have with induction hardened pins or rivets, which give a much harder surface to the bearing area of the pin. Induction hardened pins maintain a level of ductility with their thru-hardened cores.

The direction of travel for welded mill chain is determined by the application. If used in a conveyor application, the direction should be with the widest, or the open end first. If used as a drive chain, the closed end, or the end with the barrel, should be first.

Dimensions are given in inches.
