NI HARD CASTINGS
we take immense pride in offering our clients an exceptional range of Ni-Hard Castings, meticulously crafted from high-quality raw materials. Our Ni-Hard Castings are highly customizable, tailored to meet the precise specifications of our valued customers. Renowned for their exceptional durability and quality, these castings come in various grades.
Ni-Hard, a generic term for a family of white cast irons, is alloyed with nickel and chromium to confer remarkable hardness and unparalleled resistance to abrasion. This makes Ni-Hard an exceptionally wear-resistant material, especially when used in cast form. When integrated into pneumatic conveying systems, Ni-Hard Castings significantly extend the service life compared to conventional cast iron or mild steel components, thanks to their resilience against abrasive products.
The nickel content in Ni-Hard Castings plays a crucial role, and its percentage varies depending on the section size or cooling time during casting. Nickel is strategically employed to inhibit the formation of pearlite upon mold cooling. For castings ranging from 38 mm to 50 mm in thickness, a nickel content of 3.4% to 4.2% is sufficient to prevent pearlite formation. However, heavier sections may necessitate higher nickel levels, up to 5.5% to avoid pearlite formation. It's worth noting that controlling nickel content is vital, as an excess of nickel can increase the amount of retained austenite and lead to reduced hardness.
At Radhika Metal Cast, we adhere to stringent quality standards to ensure that our Ni-Hard Castings meet or exceed expectations, delivering superior wear resistance and extended service life, especially in demanding applications like pneumatic conveying systems.
