BS 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:

1. unalloyed or low alloy cast irons;

2. nickel-chromium cast irons covering two general types:

   • 4 % Ni 2 % Cr cast irons;

   • 9 % Cr 5 % Ni cast irons;

3. 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.
