General Steel Making The Cementation Process

The cementation process of making steel is also called the converting process. This process consists in impregnating bars of wrought iron or soft steel with carbon, at a temperature below its melting point, and was used (chiefly in England) for the production of high carbon bars to be employed in the manufacture of crucible steel or shear steel.

Cementation (metallurgy)

Cementation is a type of precipitation, a heterogeneous process in which ions are reduced to zero valence at a solid metallic interface. The process is often used to refine leach solutions.. Cementation of copper is a common example. Copper ions in solution, often from an ore leaching process, are precipitated out of solution in the presence of solid iron.
