H Class Mill Chain

“H” class mill chains are of one-piece cast offset link construction joined together by steel-clipped heads. They are used primarily for drag conveyor service in the lumber, pulp, and paper industries. They are also desirable for transfer and conveying purposes. “H” class mill links are cast of high-grade copper malleable iron or Duramal. Duramal is a heat-treated malleable iron having greater strength and superior resistance to wear and abrasion. Duramal chains have heat-treated pins. “H” class mill chains are interchangeable with other standard makes of corresponding sizes and numbers.
