The material in the German literature GG15HC sign, in English is GIHC (Gray Iron High Carbon).
GG-15HC: A wide range of cast iron is produced from the HC-type cast iron used in the manufacture of brake discs, because of its favorable effect of alloying on the texture and very good resistance to abrasion.

yes, you right, the iron was used in brake!
( N- O% m% B1 D/ }2 f: K0 c5 jthank you very much for your help, and do you have some standards for this grey cast alloy, I want to know where does  the data comes from;
thank you!
