As I was searching through the different treads of this forum, I found some good info regarding the bake-out, but there was not much discussion on the practices. I would like your opinion and advice on the bake-out temperature and time. So far the mnost common are the temperatures between 200°C and 400°C, but someone went as far as to recommend the stress relieving temparature. I would also like some advice on what codes or scientific articles could be helpful in establishing and justifying this requirement.

Putting Human Factor Back in Engineering
 
Hydrogen bake out is specified for hard steels (~43 HRC) susceptible to embrittlement.
The specified temperature should not exceed that of tempering (otherwise a reduction of hardness will ensue).
