FGE38-17 is a ductile cast iron material grade defined in Spain UNF standard.

This type of ductile iron possesses high ductility, exceptional resistance to shock and provides maximum toughness and machinability. Its structure is essentially ferritic and it is not readily flame hardened.

UNF FGE38-17 is equal to 60-40-18 in USA ASTM A536 standard. The followings are the chemical composition and mechanical properties for 60-40-18 ductile cast iron, which should be equivalent to FGE38-17.

Chemical Requirements:
Carbon, min, %: 3.00
Silicon, max, %: 2.50
Phosphorus, max. %: 0.08
The chemical composition should just be reference, and will not be taken as quality inspection standard.

Mechanical Properties:
Tensile strength, min, psi (MPa): 60000 (414)
Yield strength, min, psi (MPa): 40000 (276)
Elongation, min, %: 18%
Hardness, HB: 143-187

Typical Applications for FGE38-17 Ductile Cast Iron:
For components subjected to both thermal and mechanical shock and for pressure castings, valves, cylinders, parts for automotive, machine tool, marine and where soft-steel castings, steel weldments or malleable iron has been used.
