The Application of GGG40

GGG40 is a very good material grade of ductile iron, which has good tensile strength and yield strength, and especially very high elongation rate. The higher grade will mean the lower elongation, so GGG40 has the highest elongation rate in all ductile iron grades.

This material is suitable for many industrial and civil fields. Such as automotive castings, truck and agricultural parts, various machinery casting parts, manhole covers, even for pump and valve parts.
