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 stress and elastic limit have
maximum values corresponding to har
