Due
to their relatively suitable wear resistance and toughness,
high chromium cast steels are used widely in grinding
processes. Considering the application, this group of
martensitic steels has filled the gap between manganese
steels and high chromium cast irons with its suitable
impact and high abrasion resistance.
Alternatively, high chromium cast irons are universally
applicable to conditions where excessive wear and moderate
impact are present.
This
group of white cast irons will provide superior wear
resistance because of their martensitic matrix, which
is enriched with carbides. For conditions that marginal
impact and superb abrasion resistance is essential,
nickel chromium (Nihar4) white cast iron will be appropriate.
