Overview

This standard deals with the classification of specification of 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 (between 11 % and 30 %) cast irons covering four ranges of chromium content. These cast irons are widely used in the mining, earth moving, milling and manufacturing industries 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. The required structure and hardness of abrasion resistant cast irons are obtained by the selection of a suitable chemical composition and the manufacturing method. This standard does not define the abrasion resistant grades of ausferritic spheroidal graphite cast irons which are subject of the European Standard EN 1564. This European Standard has been prepared by CEN/TC 190/WG 8 "High alloyed cast iron", the secretariat of which is held by the BSI (United Kingdom). Regarding the German collaboration, the responsible Working Committee is NA 036-00-01 AA "Gusseisenwerkstoffe" ("Cast iron materials") of GINA.
