We have examined the failed or "mishap" section, and other selected sections made from 17-7 precipitation hardening stainless steel, and have concluded that the unusually large amount of retained austenite, greater than 7%, measured on the surface appears to have been produced during both the solution annealing and austenite conditioning steps of the heat treating process, but was revealed only after the austenite conditioning step. We suspect that during the heat treating process these sections may have been exposed to a furnace atmosphere that contained too much carbon or nitrogen. This exposure could have led to an increase in the amount of retained austenite both on the surface and internally.
