  NF A32-101 FGL150 Gray Cast Iron  
 

FGL150 is a low material grade of gray cast iron in France standard NF A32-101. It is equal to EN-GJL-150 in European standard EN 1561.

Application for NF A32-101 FGL150 Gray Cast Iron:
The lower grade of grey iron mainly used for applications where strength is not essential, such as counterweights etc.

Chemical Composition for NF A32-101 FGL150 Gray Cast Iron:
No any requirement about chemistry is defined in the NF A32-101 standard, but our Dandong Foundry will suggest the chemical composition of FGL150 gray cast iron according to our experience in casting industry, just for your reference.
