Sandvik releases new HX900 wear segments
May 9, 2016 By Andrew Macklin
May 9, 2016 – Sandvik Construction has launched its new HX900 wear segments, which includes bars, buttons, and runners.
HX900 wear segments maintain the original shape of vital equipment surfaces on, for example, crushers, loader buckets, chutes, excavators, rock box edges, and on weld on hammer tips.
HX900 is a wear material combining 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. HX900 wear segments are perfect for areas on your equipment that easily wear out.
A typical HX900 product has a wear resistance that is comparable with cemented carbide and a strength that is 80-90 per cent of the strength of pure nodular iron. The wear resistance is generally 5-15 times higher than with common hardened steel, Ni-hard, hard facing or ceramics.
The HX900wear segments come in three shapes for flexible and adaptable usage.
• HX900 wear buttons has a dome shape that gives maximum protection and minimizes the effect of impact. The round shape virtually eliminates any risk of weld crack propagating into the parent metal.
• HX900 wear runners protect large areas on bucket bottoms and corners. You get heavy-duty protection where you need it. Our wear runners are available in two sizes.
• HX900 wear bars make it easy to form a mosaic pattern that counters highly abrasive applications. The mild steel backing plate is notched to allow easy cutting into smaller pieces if needed.
Typically, an excavator bucket might need to be rebuilt every 3-4 months when exposed parts wear out. It’s a job that can take 20-30 man hours. That’s expensive downtime. And for a company with a lot of equipment, it can add up to a substantial annual cost. The wear life of HX900 wear segments is about five times longer than white iron and 20 times longer than quenched steel. Longer life means fewer stops, lower maintenance and operating cost, and more time for production.
Moreover, as the HX900 segments require minimum welding, which can lead to cracking of major structural components, they are an excellent alternative to hard facing. There is no preheating needed during installation and the rebuild takes about a third as long depending on application.
The new HX900 wear segments are currently being introduced at Sandvik Construction dealers all over North America.
