Cast iron with nodular graphite EN-GJS (GGG) - Sphere cast

Cast iron with nodular graphite EN-GJS (called also sphere casting) is an iron-carbon-material that carbon part being available as graphite mainly globular is (spherical) formed. This nodular graphite, which is already there in the cast state, characterises the material behaviour of cast irons with nodular graphite. Through the spherical forming of the graphite, the notching is minimal. In this way a high tensile strength is reached in the case of good percentage elongation after fracture.

Special alloys:
Mechanical and performance characteristics, such as temperature changes, wear resistance and scaling resistance can be purposefully influenced by variation of the alloy composition and/or heat treatment.
