Material properties

Ni-HiCr (Ni-Hard 4) is recognized for its superb wear resistance and toughness, suitable for severe service conditions where both abrasion and high stress are present. This material features a hard martensitic matrix with enhanced amounts of carbides, especially chromium carbides, which contribute to its exceptional wear properties.

Advantage

1. Excellent wear resistance in severe conditions.
2. Enhanced toughness compared to lower grades.
3. High resistance to impact and corrosion.
4. Maintains integrity under high temperatures.
5. Ideal for high-stress applications requiring longevity.

Application

Ni-HiCr is extensively used in areas such as mining, cement, and power generation for parts like grinding mill liners and crusher parts that need to withstand severe wear and high temperatures. It's also used in the manufacturing of pumps and heavy-duty machinery components, along with slurry transport systems and other applications where high abrasion and corrosion resistance are crucial.
