As the title states, does any guys know how to make such thermocouples from mineral insulated metal sheathed wire? We have a vey special case usage, and may need lots of thermocouples. So we are planning to make these thermocouples onsite! Is there any special steps we should follow? such as...

what's the maximum effective case depth of 31CrMoV9 nitriding workpiece U can achieve ? 0.75mm? In most Eu&U.S wind generator gear with nitriding ,which widespread effective case depth did u choose? 0.5MM? thanx everyone

hello every one? i have a question which heat treatment style(surface hardening)used in gear train of high speed rails transmission system(like TGV\ICE\shinkansen etc.) do they use induction hardening or carburization & quenching? even nitriding ? SAME the question to gear train of...

Limbowhale ?can we see the photo of the workpiece which has cracking? I think this would help us to analyse how the cracking happend?

may be u can try 65Mn(chinese trade mark,i don't konw the USA trade mark).and with flame hardening or induction hardening. the workpiece needs to be thermal refining.
