What temperature is required for hydrogen bakeout of hard chrome over steel and is it necessary to do this in an inert atmosphere?

Hello Don!

A lot of this information is compiled in AMS2759/9, 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.

Good luck!
