Re: [PSUBS-MAILIST] Cryogenic Tempering

[solomon D <solomondees@yahoo.com>]

They use croygenic tempering to make the torsion bars
that are used on Delorean doors.Similar to the ones
that are used on F16's to open the canopy.Im sure that
it could be used for something on a submarine but like
you said it is very very expensive.
