Sandvik Construction introduced its HX900 wear segments, which include buttons, runners and bars. According to the company, the wear segments have the longest wear life on the market and maintain the original shape of vital equipment surfaces on crushers, loader buckets, chutes, excavators, rock box edges and weld-on hammer tips.
HX900 is a wear material that combines the wear resistance of cemented carbide with the shock resistance, ductility and forming capability of nodular iron. This combination results in a hard material that stands well in tough environments and has long wear life, Sandvik reports.
The HX900 wear segments come in three shapes: buttons, runners and bars. The wear buttons have a dome shape that gives them maximum protection and minimizes the effect of impact. The round shape virtually eliminates any risk of a weld crack propagating into the parent metal, Sandvik adds.
The HX900 wear runners are designed to protect large areas on bucket bottoms and corners. The wear runners are available in two sizes.
Finally, the HX900 wear bars make it easy to form a mosaic pattern that counters highly abrasive applications. In addition, its mild steel backing plate is notched to allow for easy cutting into smaller pieces if needed.
According to Sandvik, the wear life of HX900 wear segments is about five times longer than white iron and 20 times longer than quenched steel. In addition, the wear segments require minimum welding, and no preheating is needed during installation.
Sandvik Construction – a business area within the Sandvik Group – provides solutions for construction industry applications, including rock quarrying, tunneling, excavation, demolition, rock building, recycling and civil engineering.
