Bibliography

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:

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 cast irons covering four ranges of chromium content:

-11 % < Cr
