WebNov 5, 2015 · The fracture toughness of good quality ferritic ( 60-40-18) ductile iron is excellent to temperatures as low as -62°C (-80°F). At this low temperature, the critical flaw size in ferritic ductile is 0.5 in. By sourcing castings from a reputable foundry, flaws of that size can be avoided. WebToday, “shrink” is more commonly applied as a scale factor to the 3d CAD file during tool build. For instance, the shrink rate for ductile iron can vary from as little as zero, on up to 1%, or 1 / 8 ” per foot, from one metal caster to the another.
