Ni Hard Nickel Institute

Ni Hard Nickel Institute

Ni-Hard 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. There are two distinct groups of Ni-Hard compositions: • the medium alloyed Ni-Hard 1 and Ni-Hard 2 with, nominally, 3.3% (resp 2.6%) C, 4% Ni, 2% Cr • Ni-Hard 4 with,

May 08, 2020 1. Mining: In mining, grinding media is used to grind mineral ore before it is processed for further metal separation. Historically, forged steel balls are being used as grinding media but gradually high chrome media has been replacing them. AIA’s growth in this segment comes from converting clients from forged media to high chrome media.

A discussion on the measurement of grinding media wear

Jul 01, 2016 The main factor that influences the absolute wear rate of a grinding body is the abrasiveness of the ore, but the choice of material for the grinding body must balance characteristics as conflicting as high hardness – which maximizes abrasive wear strength – and adequate ductility – to avoid sudden ruptures and chipping.
