Founding - Continuous cast iron bars
This European Standard defines the grades of grey cast iron and spheroidal graphite cast iron bars, which have been produced by the continuous casting process.
This European Standard specifies the characterizing properties of grey cast iron bars by either:
a) the tensile strength measured on machined test pieces prepared from samples cut from the bars, or
b) the hardness measured on the bars.
If agreed by the manufacturer and the purchaser, the combination of both tensile strength from option a) and hardness from option b) may be specified.
This European Standard specifies the characterizing properties of spheroidal graphite cast iron bars by the tensile strength measured on machined test pieces prepared from samples cut from the bars.
This European Standard specifies 4 grades of grey cast iron and 14 grades of spheroidal graphite cast iron by a classification based on tensile strength and 4 grades of grey cast iron by a classification based on Brinell hardness.
This European Standard specifies also the straightness of the bars.
This European Standard does not cover technical delivery conditions for iron castings (see EN 1559 1 [1] and EN 1559 3 [2]).

Introduction
EN 1561 and EN 1563 classify grey cast irons and spheroidal graphite cast irons respectively, which are
cast in sand moulds or moulds of comparable thermal behaviour.
This document classifies grey cast iron and spheroidal graphite cast iron bars, which are produced by
the continuous casting process.
Due to the high cooling rate during solidification and further cooling, both graphite and matrix structure
differ from those obtained by sand casting and consequently the mechanical properties in relation to
section thickness [8], [9].
The mechanical properties of continuous cast iron bars are evaluated on machined test pieces prepared
from samples cut from the bars.
However, for many applications, tensile strength or hardness are not the only interesting or
determining properties. Other mechanical or physical properties can be decisive for the use of grey cast
iron or spheroidal graphite cast iron, for example: thermal capacity, thermal diffusivity, damping
capacity, thermo-cycle fatigue and toughness.
Additional technical data for grey cast irons is given in EN 1561 and for spheroidal graphite cast irons in
EN 1563 and Annex D of this document.
1 Scope
This document specifies the grades of grey cast iron and spheroidal graphite cast iron bars, which have
been produced by the continuous casting process.
This document specifies the characterizing properties of grey cast iron bars by either:
a) the tensile strength measured on machined test pieces prepared from samples cut from the bars, or
b) the hardness measured on the bars.
If agreed by the manufacturer and the purchaser, the combination of both tensile strength from option
a) and hardness from option b) can be specified.
This document specifies the characterizing properties of spheroidal graphite cast iron bars by the
tensile strength measured on machined test pieces prepared from samples cut from the bars.
This document specifies 4 grades of grey cast iron and 14 grades of spheroidal graphite cast iron by a
classification based on tensile strength and 4 grades of grey cast iron by a classification based on Brinell
hardness.
This document specifies also the straightness of the bars.
This document does not cover technical delivery conditions for iron castings (see EN 1559-1 and
EN 1559-3).
