Ductile Nodular Iron

The corrosion resistance of ductile iron is comparable to that of gray iron with one exception under velocity conditions the resistance of ductile iron may be slightly less than that of gray iron because it does not form the same t) e of film that is present in gray iron.

The valves used in propane systems must be made from steel, ductile (nodular) iron, malleable iron, or brass. Soft parts of these valves such as gaskets, valve seat disks, packing, seals, and diaphragms must be made of materials that are certified by the manufacturer to be compatible with propane. Valve pressure ratings shall be consistent with the pressures observed in the intended application [3.14].
