GGG 70

Free from shrinkage, gas holes, sand and other tool wearing impurities No pattern cost Homogeneous and close grained structure High fatigue strength Exceptional dimensional stability Low residual stresses GGG 70 possesses a pearlitic structure, including the periphery, with percentages of 20-30% of ferrite in the core. Resistance to wear, tensile…

GGG 60

Free from shrinkage, gas holes, sand and other tool wearing impurities No pattern cost Homogeneous and close grained structure High fatigue strength Exceptional dimensional stability Low residual stresses GGG 60 has a structure that is predominantly pearlitic (>50%) in the core, which makes it specially recommended for applications requiring high…

GGG 50

Free from shrinkage, gas holes, sand and other tool wearing impurities No pattern cost Homogeneous and close grained structure High fatigue strength Exceptional dimensional stability Low residual stresses GGG 50 (170-240 HB) has a better resistance to wear than GGG 40 because of its pearlitic-ferritic structure, and is therefore recommended…

GGG 40

Free from shrinkage, gas holes, sand and other tool wearing impurities No pattern cost Homogeneous and close grained structure High fatigue strength Exceptional dimensional stability Low residual stresses Our GGG 40 products has a ferritic structure, obtained via heat treatment (130-190 HB), and is therefore used when machinability and a…

GG 35

Free from shrinkage, gas holes, sand and other tool wearing impurities No pattern cost Homogeneous and close grained structure High fatigue strength Exceptional dimensional stability Low residual stresses This is the hardest grade with the highest resistance (220-280 HB, depending on dimension). Its most important quality is the fact that…

GG 30

Free from shrinkage, gas holes, sand and other tool wearing impurities No pattern cost Homogeneous and close grained structure High fatigue strength Exceptional dimensional stability Low residual stresses This is one of the hardest grades, (190-260 HB,) and is therefore used when high tensile strength and/or resistance to wear is…

GG 25

Free from shrinkage, gas holes, sand and other tool wearing impurities No pattern cost Homogeneous and close grained structure High fatigue strength Exceptional dimensional stability Low residual stresses Our GG 25 grade offers a good combination of strength and wear resistance with average hardness (160-230 HB), while still possessing reasonable…

GG 20

Free from shrinkage, gas holes, sand and other tool wearing impurities No pattern cost Homogeneous and close grained structure High fatigue strength Exceptional dimensional stability Low residual stresses This is the softest of our continuous cast iron products, (120-200 HB) and is therefore recommended if your requirements are for good…
