Compositional ranges suggested for the manufacture of Ni-Hard grinding balls and slugs are about 3% carbon, 0.5% silicon, 0.5% manganese, 1.5-4% nickel and 1.0-2% chromium, the rest being iron. A low alloy white cast iron having a hardness and a microstructure similar to those of Ni-hard was disclosed in Canadian Patent No. 1,125,056 owned by the present assignee.

02/10/2017· Quenching from 950°C with compressed air cooling and tempering at 250°C for grinding balls of chromium-nickel white cast iron makes it possible to improve wear resistance and hardness. The main structural components governing wear resistance are carbide phase and a martensitic matrix. The maximum hardness (65 HRC) is achieved after quenching from

14/05/2014· The nickel-chromium white cast irons are also usually classified as Ni-Hard types 1 to 4. Ni – Cr white cast irons are also known as Ni hard irons. These white cast irons are being produced for over 50 years and are the oldest group of high alloy white cast iron of industrial importance. Ni hard white cast irons are very cost effective,

26/03/2020· Chromium: Alloy cast iron where high abrasion and wear resistance are essential especially in applications like crushing and grinding, Chromium is essential alloying addition. With Nickel’s addition, the graphitization process also speeds up generating high carbon flakes. Chromium addition suppresses the graphitization process initiated due to the addition of
