Overview
NiHard is a well-established white iron product alloyed with nickel and chromium to give significant abrasion and impact resistant properties. The structure of NiHard is composed of iron and chromium carbides, fixed in a matrix rendered martensitic by the nickel content. This structure allows NiHard to be utilized in abrasive and high impact conditions found throughout the construction, mining, manufacturing and mineral processing industries.
