SuperExpanite C

An alternative to SuperExpanite NC, where only carbon is applied; and the name is SuperExpanite C.

The “C” in SuperExpanite C stands for Carbon. This means it is a carburizing process, as opposed to a nitro-carburizing process, such as the SuperExpanite NC, which includes nitrogen. Nitrogen is eminent for hardening, due to its ability to achieve a high hardness and superior corrosion properties, even after the hardening process. When introducing nitrogen the part will become slightly magnetic, which may be an unwished property in some applications. More severe however, is the fact that it may be difficult to weld on a material hardened with the use of nitrogen.
