Rexnord Cast Chain provide an alternate to welded and fabricated steel chains in applications where severe corrosion or heat is a problem. They are constructed of cast offset links and coupled with steel pins or rivets. Cast chains may be slightly better suited to applications involving severely corrosive atmospheres or where chain temperatures reach above 500 °F. Cast Combination chains may provide superior service where heavy downward loading and sliding across an extremely gritty or abrasive surface has resulted in a chain wear problem. Where, in addition, problems have been encountered with chain breakage due to heavy impact loading.
