Product Description

Product Description

Our cast link chains offer a remarkable advantage with their unified, one-piece construction, eliminating the need for press fits or welds. This innovation allows for almost infinite flexibility in material selection, ensuring precise alignment with customer demands for corrosion resistance, heat resistance, abrasion resistance, or an optimized blend of all three.

IRONS - In the realm of conventional links, spheroidal graphite iron has triumphantly supplanted the white heart malleable iron once used. This transition to ductile material unlocks a vast spectrum of mechanical properties, elevating performance to new heights.

The strategic implementation of Austempered Ductile Iron brings a notable edge, offering fully pearlitic characteristics. Through a specialized austempering heat treatment process, it delivers mechanical properties akin to alloy steels, yet maintains a lighter weight typical of iron. An added cyanide quench operation further enhances this material by introducing a unique work-hardening characteristic.

CAST STEELS - Engineers are empowered to choose the optimal steel for diverse applications. Whether it's the resilient 420 high chrome steel for heat and abrasion resistance in moving grates, or the robust high manganese steel that work hardens under stress, these materials excel in demanding environments like cement clinker transport, where durability is paramount.

UNIISO IND. stands at the forefront of innovation in Cast Link Chain fabrication, utilizing high-grade irons and steels. Since our foundational days, we've maintained our legacy of excellence despite evolving chain standards. Our flagship product, the UNIISO VA759 CHAIN, features a precise 200mm pitch and is crafted from premium casting steel, offering a remarkable Ultimate Tensile Strength of about 300kN. This ensures extraordinary longevity and performance even in the most challenging applications.
