HYSTER WEAR SYSTEMS INCLUDE:
 
Hyster White Iron Wear Block(700BHN-63HRC)-- Range of products based on a composite white iron wear surface metallurgically bonded to a weldable mild steel backing plate. Wear block is fixed to the surface of fixed and mobile plant equipment, such as mining buckets and chutes, where protection from severe abrasion is required.
 
Hyster Overlay Wear Plates--Chromium carbide clad wear plate manufactured in HYSTER and marketed worldwide. Overlay plate is well suited to fixed and mobile plant equipment associated with the construction, mining and resource industries; particularly iron ore, coal, cement and steel applications.
 
Hyster NiHard(NiHard 4, Nihard 1&2)--Abrasion and high impact resistant product. It is often cast into wear billets and wear liners and used extensively in the mining, construction and mineral processes industries, particularly in bulk handling situations.
 
Features and Benefits
• Reduced Maintenance
• Protects any high wear area, eliminating the need for frequent rebuild or replacing wear plate
• Lasts longer than other wear protection
• Excellent alternative to hard facing which can lead to cracking of major structural components Increased Productivity
• Reduced maintenance ensures maximum machine availability
• Wide variety of shapes and sizes allows small areas to be protected, minimizing the affect on penetration and material flow
• Lower Operating Cost
• Can be fit to flat or curved surfaces, eliminating the need to have wear plate formed to fit
• Bucket life is significantly increased, minimizing repair and new bucket orders
