This European 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 standard are:
a) unalloyed or low alloy cast irons;
b) nickel-chromium cast irons covering two general types:
- 4 % Ni 2 % Cr cast irons;
- 9 % Cr 5 % Ni cast irons;
c) high chromium cast irons covering four ranges of chromium content:
- 11 % < Cr </= 14 %;
- 14 % < Cr </= 18 %;
- 18 % < Cr </= 23 %;
- 23 % < Cr </= 30 %.
This European Standard does not define the abrasion resistant grades of ausferritic spheroidal graphite cast irons which are subject of EN 1564.
