GGG-40 is a typical high-ductility ductile iron (also known as nodular cast iron or spheroidal graphite cast iron) that combines the castability of gray iron with the toughness of forged steel. Its graphite is distributed in spherical form, boasting a tensile strength ≥ 400 MPa, elongation of 15–18%, and an elastic modulus close to that of carbon steel. Strictly controlled chemical composition and spheroidizing and inoculation treatments ensure stable microstructure and excellent performance. Widely used in automotive crankshafts, chassis components, heavy machinery gears, and municipal manhole covers, GGG-40 significantly reduces machining costs compared to forged steel while maintaining long service life, making it a cost-effective engineering material choice.
