65-45-12 Ductile Iron Round Bar (62)


65-45-12 Ductile Iron Round Bar (62)

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. This specification conforms to ASTM A536 grade 65-45-12. The microstructure consists of Types I & II nodular graphite as defined in ASTM A247. The matrix is ferrite with approximately 5-25% pearlite. The “rim” will have a higher nodular count and will be mostly ferrite. Chill carbides will be less than 5% in any field at 100x and will be ...
