NF A32-201 FGS800-2 is a high material grade of ductile iron used in France, also equal to the grade QT800-2 in China standard GB 1348.
This material grade is also equal to the following grades:
EN-GJS-800-2 in European standard EN 1563
120-90-02 in USA standard ASTM A536
Grade 800-2 in ISO standard ISO 1083
GGG80 in Germany standard DIN 1693
FCD800 in Japan standard JIS G5502
GS800-2 in Italy standard UNI 4544
800/2 in UK standard BS 2789
The chemical composition of NF A32-201 FGS800-2 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.
