Gray Iron - Information:
Basic Grey Iron is carbon in
the form of graphite and silicon. To refine the grain size of the
graphite Manganese, copper are used to strengthen and refine the
iron. Chromium is added to harden and Nickel is added to strengthen.

Ductile Iron - Information:
These are Irons alloyed with
a high percentages of Nickel and Chromium. Basically they are the
iron equivalents of Stainless steel in their properties.

Ni-Hard - Information:
In these irons a
development of iron-chromium carbides produce a tougher more
abrasion resistant iron. The variation of carbon content effects the
toughness and abrasion resistance. Greater carbon increases the
resistance to abrasion, however at the loss of toughness and vice
versa lowering the carbon increases toughness but decreases the
resistance to wear. Hardness ranges dependent on section thickness
can be between 450-600 BHN
The use for Ni-Hards is in
pulverizing, crushing and impact wear plates also in heavy duty pump
casings and impellers for slurry and gravel applications.
