按德国牌号标准，GG-15是灰铸铁，15表示抗拉强度150MPa。另外的符号啥意思不知。

德国的合金灰铸铁，后面为合金元素

HC:High Carbon Cast Iron; Cu,Cr is the mainly alloy element.
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.
The 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.
Mechnical property:Hardness: 180 ± 5 HB, Tensile strength:240 MPa.
The cast GG15HC marked characteristics:
- High thermal conductivity,
- Low thermal stresses,
- High resistance against cracking due to heat generated,
- Good shock absorption properties.
