Mechanical properties of malleable cast iron

· For parts that are to be pierced, coined, or cold formed

· For parts requiring maximum machinability

· For parts that must retain good impact resistance at low temperatures

· For parts requiring wear resistance (martensitic malleable iron only)

Ductile iron has a clear advantage where low solidification shrinkage is needed to avoid hot tears or where the section is too thick to permit solidification as white iron (Solidification as white iron throughout a section is essential to the production of malleable cast iron).

How to judge the performance of Malleable cast iron ?

Firstly you can check the elongation

Secondly you can see whether there is any cross section in the internal thread

Thirdly if there is any loose loose.
