Can anyone tell me what the CR stands for on the old DIN GG-26 gray iron specification?

A Google search indicates that it is an alloy cast iron for wear resistance contaning Cr + Mo. The % of contents and mechanical properties I am unable to get. The application mentioned is for a die part and a wear pin

it is %26-30 Cr and %1 Mo it is hard as cast and not mashiable it is used for parts under sever abrasion and errosion for example salary pumps and grinding balls there is standard ASTM A532 for these types

feraidoon,
please give me the reference for the grade. My literature search indicates that it is a machinable grade and the alloy contents are in the low range.

I am familiar with ASTM 532,. Thanks
