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.
