24、DIN EN 12513:2011-05 EN 12513:2011 (E) 4 Introduction This European Standard deals with the classification of abrasion resistant white cast irons in accordance with their chemical composition and hardness. Such cast irons are widely used in the mining, earth moving, milling and manufacturing industr

25、ies where high resistance to abrading minerals and other abrading solids is required. The abrasion resistance of these cast irons depends on them having the appropriate structure and hardness for the application. These properties are obtained by careful control of the material composition and the pr

26、ocessing route. In this edition of EN 12513, the designation by symbol is based on Brinell hardness instead of Vickers hardness, because it corresponds better with the measurement method applied in practice. In this European Standard a new designation system by number, as established in EN 1560, is

27、given. NOTE This designation system by number is based on the structure and rules of EN 10027-2 and so corresponds with the European numbering system for steel and other materials. DIN EN 12513:2011-05 EN 12513:2011 (E) 5 1 Scope This European Standard defines the grades of abrasion resistant white

28、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

29、 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. 2 Normative reference
