Material properties

Ni-Hard 1, designated under ASTM A532 Class 1 Type A, is a type of Ni-Cr-HC (Nickel-Chrome-High Carbon) white cast iron known for its excellent wear resistance and toughness. This material is particularly noted for its capability to resist abrasion and impact, making it ideal for heavy-duty applications. The alloy is characterized by its hard martensitic matrix with embedded carbides, which significantly enhance its wear properties. The high hardness level is primarily due to the presence of nickel and chromium, which also provide some corrosion resistance, albeit secondary to its wear properties.

Advantage

1. Exceptional wear resistance.
2. High hardness and toughness.
3. Good resistance to impact.
4. Limited corrosion resistance.
5. Suitable for heavy-duty applications.

Application

Ni-Hard 1 is extensively used in industries where durability against impact and abrasion is critical. Typical applications include the mining sector for ore processing equipment like grinding mills and crusher parts. It's also used in the manufacturing of pumps and heavy-duty machinery components which are subjected to high wear conditions. Furthermore, Ni-Hard 1 is employed in the construction and manufacturing of slurry transport systems and other applications involving abrasive materials.
