Where to buy cheap iron castings
- on Mar. 23, 2011
As for a buyer for iron castings,
the prices are always the most
important consideration. In my works
in iron foundry for many years, I

prices were the cheapest in the
world. Unfortunately, we were not.
There are many iron foundries
worldwide who could produce the iron
castings by the lower costs than
ours.

Nodulizing Grades of Ductile Iron
- on Mar. 14, 2011
Nodulizing grades are also called as
nodularity grades, nodularization
grades, or percent of
spheroidization. It is a very
important indicator to evaluation
the quality of ductile iron
microstructure. High nodulizing
grade means the high quality and
better mechanical properties of iron
casting parts.
