In part 1 of our series on ductile iron vs steel we did a general comparison of the two alloys to determine which might be the better option for a given application. The blog was intended to be a generic overview. In this second part, we specifically take a brief look at how ductile iron and steel match up when it comes to machining.
As a side note: Check out this blog we wrote comparing ductile iron and gray iron.
Ductile iron has the following machining advantages compared to steel:
When discussing the intermediate-strength grades of ductile iron, the ductile iron has a better machinability than steel because:
These two “properties” are why ductile iron has greater depth diameter drilling ratios, faster feed rates, higher spindle speeds and extended tool life.
For more information on machining ductile iron one should consult the Machinery Handbook and/or your cutting-tool supplier.
