FGS700-2 is a high material grade of ductile cast iron in France standard NF A32-201. It is equivalent to the grade EN-GJS-700-2 in European standard EN 1563.
This material grade is also equal to the following grades:
100-70-03 in USA standard ASTM A536
Grade 700-2 in ISO standard ISO 1083
QT700-2 in China standard GB 1348
GGG70 in Germany standard DIN 1693
FCD700 in Japan standard JIS G5502
GS700-2 in Italy standard UNI 4544
700/2 in UK standard BS 2789
The chemical composition of NF A32-201 FGS700-2 ductile cast iron:
In standard NF A32-201, there is no requirement to the chemical composition, so the iron foundry could adjust their chemical composition as their experience, but the mechanical properties are the necessary requirement.
