CONTINUOUS CAST IRON
Dura-Bar Gray Iron contains flake
graphite in matrix structures that range from all pearlite to pearlite plus ferrite. The
matrix structure will influence machinability, strength, hardness and wear
characteristics. In general, a fully pearlitic matrix will have the best mechanical
properties and will be readily machinable. Iron bars containing ferrite in the matrix will be
easier to machine but will be lower in strength and wear resistance.
Continuous cast Dura-Bar Ductile Iron contains nodular graphite in a matrix of pearlite and ferrite.
The spheroidal shaped graphite maximizes the strength in cast iron. The
ratio of ferrite to pearlite in the matrix varies in each of the three
grades in order to produce the required tensile and yield strengths and
elongation properties. The nodular graphite provides the same free
machining benefits as lead (steel) without the machining and waste
