Abrasion-resistant cast irons. Classification
This International Standard defines the grades of abrasion-resistant white cast irons. It specifies the grades in terms of:
chemical composition;
hardness.
The types of abrasion-resistant white cast irons covered by this International Standard are:
unalloyed or low alloy cast irons;
nickel-chromium cast irons covering two general types:
4 % Ni 2 % Cr cast irons;
9 % Cr 5 % Ni cast irons;
high chromium cast irons covering five ranges of chromium content:
Cr > 11 % to ≤ 14 %;
Cr > 14 % to ≤ 18 %;
Cr > 18 % to ≤ 23 %;
Cr > 23 % to ≤ 30 %;
Cr > 30 % to ≤ 40 %.
