FGL250 is a material grade of gray cast iron defined in France standard NF A32-101. FGL250 is the most common cast iron and the most widely used cast material based on weight.

The followings are the applications, chemical composition, technological and physical values, mechanical properties, and equivalent grades for NF A32-101 FGL250 gray cast iron.

Application for NF A32-101 FGL250 Gray Cast Iron:
FGL250 gray cast iron is used for housings where the stiffness of the component is more important than its tensile strength, such as internal combustion engine cylinder blocks, pump housings, valve bodies, electrical boxes, and decorative castings. Grey iron also has very good damping capacity, hence its use as the base for machine tool mountings.

The following castings are made of FGL250 gray cast iron by our Dandong foundry.
