We offer our client an excellent quality range of Ni-Hard Castings
, which are manufactured from high grade quality raw materials. These NiI-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:
• 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.
