German term

Hartmangan

German to English Tech/Engineering Materials (Plastics, Ceramics, etc.) Electric Locomotive
"Die Zug- und Bremskräfte werden über mit Hartmangan plattierte und gefederte Anschläge vom Drehgestell auf den Drehzapfen bzw. Lokkasten übertragen."

From a text about a kind of electric locomotive. Mangan is manganese, so is Hartmangen simply hard manganese, or does it have some other specific name? TIA for your help.

austenitic manganese steel or Hadfield manganese steel

I am currently translating a book on ferrous materials. Hartmangan = Manganhartstahl. This is a special type of heat-treated steel.
See the ref. for more information that you'll ever want to know.

Peer comment(s):

agree Kevin Lossner : Plausible enough. It certainly isn't braunite in this context.

agree transatgees : Named after the Sheffield-based company which invented this steel (15% manganese, if I remember correctly).

good memory: "....containing about 1.2% C and 12% Mn, was invented by Sir Robert Hadfield in 1882....." Some some reason, Prof. Berns insists on using Hadfield manganese steel rather than austenitic, well, he is one of the foremost German experts

high tensile-strength manganese

I'm not sure about this and I'm also not sure about the hyphen.

austenitic hard manganese steel

Not absolutely sure, as I don't see the "steel" element, but the reference below talks about it in conjunction with railway components:

What I don't know is whether the steel must by definition be austenitic (i.e. would martensitic steel form an equally tenacious alloy?).
