Sandvik Construction, Stockholm, Sweden, launches new HX900 wear segments; bars, buttons and runners. HX900 wear segments have the longest wear life on the market and 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. This means fewer stops, lower maintenance and operating cost and more time for production.
A versatile product with unique wear properties
HX900 is a wear material designed to combine the wear resistance of cemented carbide with the shock resistance, ductility and forming capability of nodular iron. The wear segments are perfect for areas on your equipment that easily wear out, according to the company.
A typical HX900 product has a wear resistance that is designed to be comparable with cemented carbide and designed to have a strength that is 80-90 percent 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, according to the company.
Use HX900 wear segments on, for example, crushers, loader buckets, chutes, excavators, rock box edges, weld on hammer tips and in all places that are inaccessible for installation of wear liners. In such applications, the company says, HX900 can easily replace conventional wear resistant steels, castings and hard facing on wear parts subjected to severe stresses.
HX900 wear segments come in buttons, bars and runners.
The HX900wear segments come in three shapes for flexible and adaptable usage.
- HX900 wear buttons has a dome shape designed to give maximum protection and minimize the effect of impact. The round shape is designed to eliminate any risk of weld crack propagating into the parent metal
- HX900 wear runners are designed to protect large areas on bucket bottoms and corners.
- HX900 wear bars are designed to 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.
Benefits and profitability you can count on
The wear life of HX900 wear segments is about five times longer than white iron and 20 times longer than quenched steel, the company says. 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, the company says. 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.
