The classification, properties and applications of abrasion resistant cast iron
It is known to us that, in order to increase
the strength, toughness and
hardness and wear resistance,
iron foundries often add an appropriate amount of Cu, Cr,
Mo, W, Ni, Mn and other alloy elements into the
cast iron. But different
elements can bring different characters to cast iron. So it is
important to classify different kinds of cast iron, make sense of
where it should be applied. Let me introduce briefly as follows:

In China, abrasion resistant cast iron have
been used in many fields, made great contribution to the development
of economic. Many iron foundries such as Dandong Foundry are
making effort to develop and supply consumers with cast iron of high
quality. People can choose the most appropriate kind of abrasion
resistant cast iron basing on their own need.
