WH78-4-B Welded Steel Chain Sprockets

Welded steel chain spikets are manufactured using a process that involves the welding of 2 pieces of metal together without the use of filler materials. After the welding process, the excess material is removed and the welded chain is then calibrated for length. To ensure a high degree of strength, welded chains are tested by cutting a sample from a production run. This is done several times a shift and the data is recorded electronically. Some chains are twisted and used as tire chains.
Welded steel chain has an offset sidebar construction and no rollers. These chains are great for applications requiring high impact and abrasion resistance. The welded steel chain features a pin that is fully 360-degree heat-treated for optimum wear life. Its distinctive offset style sidebars are welded to the sidebars and are riveted to a steel core.
