Jargon – Our Small Glossary
Different and unclear notions of heat treatment terms often lead to misunderstanding, uncertainty and sometimes even unwanted component properties. For example, what should be understood from the term ‘case hardening depth (CHD)’ following a case hardening process?
- In this depth, should there also be a hardness of 60 HRc corresponding to the required surface hardness?
- Maybe it is the depth, at which the hardness has sunken to that of the components core?
A clear definition of the CHD can, for example, be found in DIN EN 10052, which defines the terms for the heat treatment of ferrous materials. Our small glossary of “the mutual language” describes terms in reference to this standard. It should help to prevent misunderstanding and faults. The selection of terms is based on our practical experience. We welcome your suggestion for further additions.
