CEN/TC 190/WG 8 - High alloyed cast iron

This European Standard specifies the grades and corresponding requirements for austenitic cast irons. These requirements are specified in terms of:
graphite form and metal structure: either flake or spheroidal graphite in an austenitic matrix;
chemical composition: as given for each of the grades;
mechanical properties measured on machined test pieces prepared from cast samples.
This standard does not cover technical delivery conditions for iron castings, see EN 1559-1 [1] and
EN 1559-3 [2].

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 -   14 % < Cr -   18 % < Cr -   23 % < Cr This European Standard does not define the abrasion resistant grades of ausferritic spheroidal graphite cast irons which are subject of EN 1564.

This European Standard specifies the grades and corresponding requirements of austenitic cast irons. These requirements are specified in terms of: - graphite form and metal structure: either flake or spheroidal graphite in an austenitic matrix; - chemical composition: as given for each of the grades; - mechanical properties: obtained from separately cast samples.

This European Standard defines the grades of abrasion resistant white cast irons. It also 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 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.
