Steel 20MnCr5E
Steel 20MnCr5E
(OP)
I've come across a reference to the above steel.
Can anyone tell me what is the difference between 20MnCr5E and the 'ordinary' 20MnCr5 I am familiar with??
TIA
Peter

RE: Steel 20MnCr5E
The E is indicating that the material/part has been case hardened. E and V are informally placed at the end of a steel designation to indicate the following:
E = Einsatzgehärtet = Case Hardened
V = Vergütet = Quenched and Tempered
I use the term informally because I have never seen this explicitly stated in a DIN standard, although it is somewhat commonly used in German-speaking countries.

Sorry about that and I thank TVP for setting me straight.
