The Iron Alloys
Bronze carries Dura bar's Continuous Cast Iron Products in number of
shapes and sizes. We carry G2 Gray Iron (Class 40) and Ductile Iron's
65-45-12 and 80-55-06.
Which one do you need?
G2 Gray Iron
G2 is a pearlitic gray iron containing Type A graphite. Gray Iron bars
made to this specification have optimal strength, wear and hardness when
compared to the other gray iron grades. This material is well suited
for applications requiring high resistance to wear and response to heat
treatment. This specification is similar to ASTM A48 class 40.
65-45-12 Ductile Iron
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.
80-55-06 Ductile Iron
80-55-06 ductile iron will contain nodular graphite in a matrix of
ferrite and pearlite. The pearlite/ferrite structure provides higher
wear resistance and strength when compared to a ferrite grade of ductile
iron. This material is readily machinable with good surface finishes.
Tensile and yield strengths are similar to AISI1040 steel in the
as-rolled condition. This specification is similar to ASTM A536 grade
