Continuous Cast Iron Bar
Continuous casting virtually eliminates porosity, inclusions, burned-on impurities, and surface flaws. Cast iron bars are usually alloys that contain more than 2% carbon and from 1% to 3% silicon. Cast iron bar is offered in gray and ductile types. We stock ductile cast iron round bars. The major difference in these types is the shape and distribution of graphite in their microstructure. 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. Ductile iron has higher machining speeds than steel and there is usually no need for deburring machined parts. The graphite flakes in the cast bar act as a self-lubricant and provide better lubricity. Ductile iron can be flame or induction hardened as well as deep hardened. Ductile iron can be used to machine pistons, glands, caps, manifolds, rams, and valve bodies. 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.
We currently stock 22 imperial sizes of ductile iron round bar available from 2 inch to 16 inch diameter. The iron bars are stocked in 12 or 24 ft. lengths and can be cut to length. All sizes are produced oversized to ensure cleanup. Standard packaging is used to prevent damage to the material during shipping. If you need custom packaging for your order, please let us know what your requirements are and we will accommodate your specific needs.
