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. 
The design allows for operating conditions that are less than desirable. Their rugged welded construction permits high speeds, minimal lubrication and easy modification for application specific attachment. Welded steel mill chain are also interchangeable with other standard makes of corresponding sizes and numbers.Dimensions are given in inches. 
Material: 
Sidebars and barrels are medium carbon steel. Pin are medium carbon alloy steel and are the hardened for maximum chain life.
