What happens when a steel gets tempered?
What happens when a steel gets tempered?
(OP)
My first post at this forum.
This maybe very simple question for some of you but I really wanted to know what happens to the material in my case steel, when it gets tempered at high temperatures (e.g 800 C)?
- What happens to the inner material structure?
- How does the variation in the structure affect the resistivity and consequently the conductivity?
Thank you all for your help

@ stanweld : Yes - E.g. 6%C Steel at temperature of 800 C.
@ WSALDUA : Thanks - Yes i mean heat treated when i say tempered.
What element in Steel structure hugely affects its resistivity and hence its conductivity?

RE: What happens when a steel gets tempered?
To tell you the truth, I don't have much background on metallurgy and materials, as I am from an Electronic background.
So since you are from materials background, do you know what happens to the grain size and the grain orientation of the transformer steel, when they are heat treated?
in other words, what change occur to the grain size and grain orientation of these materials, making them change their properties ( properties such as resistivity, conductivity and permeability?)
Thank you
RE: What happens when a steel gets tempered?
As for elemental factors it is highly dependent on the steel in question. I suspect that some graphite will form as an inclusion depending on the cooling rate. Here orientation is important as graphite is isotropic when it comes to electrical properties. Also do you mean 6% silicon? Electrical steel is high in silicon. Higher silicon tending to increase resistivity.
hope this helps some
