Information
- We offer our client an excellent quality range of Ni-Hard Castings, which are manufactured from high grade quality raw materials. These Ni-Hard Castings can be customized as per our valued customers specifications. These Ni-Hard Castings are widely known for its durability and quality. We manufacture all types of Ni-Hard Casting Grade 1, 2 & 4.
- Ni-Hard is the generic name for a family of white cast irons alloyed with nickel and chromium to give high hardness and outstanding resistance to abrasion.
- Ni-Hard is an extremely wear resistant material and in cast form is ideal for use with abrasive products, giving a much more extended life when compared with cast iron or mild steel when incorporated in pneumatic conveying systems.
- Nickel content increases with section size or cooling time of the casting to inhibit pearlitic transformation. For castings of 38 mm to 50 mm thick, 3.4% to 4.2% Ni is sufficient to suppress pearlite formation upon mold cooling. Heavier sections may require nickel levels up to 5.5% to avoid the formation of pearlite. It is important to limit nickel content to the level needed for control of pearlite; excess nickel increases the amount of retained austenite and lowers hardness.
There are two distinct groups of Ni-Hard compositions
A typical chemical analysis of this material:
- The medium alloyed Ni-Hard 1 and Ni-Hard 2.
- Ni-Hard 4.
These alloys are standardized in almost all industrialized nations under various designations.
