FGS400-12 is a ductile cast iron grade in France standard NF A32-201, which is equivalent to EN-GJS-450-10 in European standard EN 1563.
This material grade is also equal to 60-42-10 and 60-45-12 in USA standard ASTM A536, Grade 450-10 in ISO standard ISO 1083, QT450-10 in China standard GB 1348, FCD450 in Japan standard JIS G5502, GS400-12 in Italy standard UNI 4544, 420/12 in UK standard BS 2789, etc.
The chemical composition of NF A32-201 FGS400-12 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.
