These chains are constructed with malleable cast block links and steel connecting links. Used for conveyor and drag applications. Promac cast combination chain is designed to work in tough and abrasive environments at a moderate cost.

Pearlitic malleable iron is used for block link wear resistance and provides balance toughness.
Pins are made of selected steel and heat treated to achieve superior strength.
Assembled with high interference fit and consistent set down for greater fatigue strength and dimension integrity.
