A lot of this information is compiled in AMS 2759/9, on "Hydrogen Embrittlement Relief (Baking) of Steel Parts". The temperatures listed there are
for carburized steel substrates, 275 °F
for 52100 and 440C substrates, 300 °F
for music wire, 325 °F
for all others, if necessary, 375 °F.
Air atmosphere is standard.
