Specifies grades of abrasion resistant white cast irons and defines grades in terms of chemical composition and hardness.

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: unalloyed or low alloy cast irons; nickel-chromium cast irons covering two general types: 4%Ni 2%Cr cast irons; 9%Cr 5%Ni cast irons; 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 EN1564.
