Carburizing - Wikipedia

Carburising, carburizing (chiefly American English), or carburisation is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder. Depending on … See more Carburization of steel involves a heat treatment of the metallic surface using a source of carbon. Carburization can be used to increase the surface hardness of low carbon steel. Early carburization … See more There are different types of elements or materials that can be used to perform this process, but these mainly consist of high carbon content material. A few typical hardening agents … See more Typically the materials that are carbonized are low-carbon and alloy steels with initial carbon content ranging from 0.2 to 0.3%. The workpiece surface must be free from contaminants, such as oil, oxides, or alkaline solutions, which prevent or impede the … See more • Carbonitriding • Case hardening • Cementation process See more There are all sorts of workpieces that can be carburized, which means almost limitless possibilities for the shape of materials that can be carburized.

WebAug 17, 2024 · Whereas steel requires a carbon content of no more than 2 percent, cast iron usually contains 2 to 3.5 percent carbon. It's the carbon content that gives cast iron its rough, slightly bumpy feel. Its higher carbon content makes cast iron more brittle than steel (which is why it needs to be so heavy and thick—if it were thinner, it would break). WebApr 9, 2024 · Mitsui & Co., Ltd.
