Product description

At chilled cast iron the name is the program: an extreme abrasion resistance of the iron-carbon alloy makes this material ideal for camshafts, ore crushers, grinding plates and even for armour plates for mills.

Here the reason is in the inclusion of carbon. At chilled cast iron carbon is not present as graphite, but it is bind as iron carbide in high concentration. Typical for chilled cast iron is the so called white fracture. In analogy we are referring to this also as white cast iron.

Non-alloyed steel will be especially hard with ledeburite (austenite and cementite), which forms during the meta-stabile solidification of cast iron, also called white solidification.
At highly alloyed chilled cast iron carbides from chrome, molybdenum, vanadium or niobium develop.

We can achieve a stabile solidification of cast iron also through a slight cooling phase or via a bigger wall thickness of the part. In that case again graphite is formed from a matrix of ferrite and perlite.
