Founding. Abrasion resistant cast irons. | Status: Confirmed, Current

1 Scope 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. a) unalloyed or low alloy cast irons;
2. b) nickel-chromium cast irons covering two general types:
   • — 4 % Ni 2 % Cr cast irons;
   • — 9 % Cr 5 % Ni cast irons;
3. 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.
