7. Fabrication & Processing Comparison
EN-GJS-500-7 Ductile Cast Iron Characteristics:

Machinability: Good machinability (~75% of C36000 baseline). Mixed ferritic-pearlitic structure delivers smooth finishes and moderate tool life.

Weldability: Difficult to weld. Preheat to 250°C and use nickel-iron (ENiFe-CI) electrodes with controlled interpass temperatures.

Formability / Cold Working: Limited localized deformation only.

Heat Treatment & Annealing: Typically used as-cast. Normalizing from 900°C increases pearlite and strength.

EN-GJS-600-3 Ductile Cast Iron Characteristics:

Machinability: Moderate machinability (~65% of C36000 baseline). Predominantly pearlitic structure requires rigid setups and carbide tooling.

Weldability: Difficult to weld. High risk of martensite formation in the heat-affected zone; requires 300°C preheat and nickel-iron filler wire.

Formability / Cold Working: Non-deformable.

Heat Treatment & Annealing: Typically utilized as-cast or normalized from 900°C.
