DIN 1693-1 GGG-60 Cast Iron: High-Strength, Wear-Resistant Material for Industrial Use
GGG-60, a perlitic-ferritic cast iron material for cast pieces for static and dynamic loading in machines and construction of vehicles as well as in the machine tool manufacture, in civil engineering and energy industry with increased strength and wear-resisting quality, crankshafts, wheel hubs, brake housing, tunnel rings, face plates for centre lathes, camps of high-pressure grease guns, tables for machine tools. The material is comparable to UNS F 33800 of the USA.
