About Ductile Iron

Nodular iron or Spherical. We take away as much as possible and innoculate with a MG Alloy. This causes graphite to form in spherical clumps instead of flakes. This has a tremendous effect on mechanical properties.
Yield : 276 MPA, 40Ksi.
Ultimate : 414MPA, 60Ksi
Ductile : 18% EL
1. Please Note : Elements such as copper or tin may be added to increase tensile and yield strength while simulataneously reducing ductile. Improved corrosion resistance can be achieved by replacing 15% to 30% of the iron in the alloy with varying amounts of nickel, copper or chromium
This is very important - has steel like properties in a casting
