65-45-12 ductile iron contains nodular graphite in a matrix of ferrite with small amounts of pearlite. The ferritic structure gives excellent machinability with good surface finishes along with optimal impact strengths, fatigue properties, electrical conductivity and high magnetic permeability. This iron has approximately the same tensile and yield strengths as AISI 1020 steel in the as-rolled condition.

Typical Applications

Hydraulic-pump rotors, gear blanks, rams, machine-tool gibs, foundry patterns plates, ways, collets, valve bodies, manifolds, compressor valves, hydraulic cylinder bushings, rod bushings, etc.
