am i stupid on hydrogen embrittlement ?
am i stupid on hydrogen embrittlement ?
(OP)
we clean oily parts in some solvent which has a pH value around 10.5. so, this solvent is no way acidic. to me, there will be no free hydrogen atoms. but army tells me it will cause high strength steel hydrogen embrittlement. am i out of my mind?
thanks.
thanks.

In some cases even reactions in the solution that do not result in corrosion (where the metal may be a catalyst) will generate H.

Conditions are temperature, concentration, exposure time and other chemicals used in the cleaning solution. In general, you should experience no cracking at temperatures below approximately 150 F. You need to be more forthcoming in divulging just what is in your cleaning solution, the time and temperature of exposure, and the alloy steel and its mechanical properties (based on heat treatment) in order to receive meaningful info.

to clean oily parts made from 4340 (Chrome plated), 17-4ph, and 440C. (all >150 kpsi)
sorry, i thought at pH 10.5, those not matter too much.
thanks.
