Description

GGG-80, a perlitic cast iron material with nodular garphite, for cast pieces with high strength and hardness, e.g. milling head body, pinion, cast pieces for high wear loadings, e.g. scratch, snail wheel segments for construction machines, meal course segments. The material is comparable to UNS F 36200 of the USA.
