1 i7 c$ L& X1 Q* _% n3 eGG-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.
  n. m2 ^$ d$ Y! t0 HThe cast-iron texture: Graphite (%) 12.5, Graphite shape IA3, Perlite (%) 99, Ferrite (%) <1;
Chemical composition: C 3.73, Si 2.07, Mn 0.78, P 0.058, S 0.085, Ti 0.014, Cu 0.56, Cr 0.27, Sn 0.039.

yes, you right, the iron was used in brake!
thank 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!
