EVS-EN 12513:2011

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.
