DIN EN 1564:2012-01

This European Standard classifies ausferritic spheroidal graphite cast irons in accordance with the mechanical properties of the material. Five grades of ausferritic spheroidal graphite cast iron are defined by the mechanical properties measured on machined test pieces prepared from cast samples. When, for these grades, hardness is a requirement of the purchaser as being important for the application, Annex C provides guidance values for hardness. Two grades of ausferritic spheroidal graphite cast iron are defined in Annex A in accordance with their hardness. These cast irons are used in applications (e. g. mining, earth moving) where high abrasion resistance is required. In this standard a new designation system by number, as established in EN 1560, is given.
