Cryogenically Freeze Valve Springs?
Any merit to this to help avoid spring breakage?
Basically like the process done to rotors and other such components. They are slowly brought down to cryo level temps, then slowing brought back up to a high temp, then cooled back to room temp. This strengthens the moleculure structure.

I'm sure springs would be no more than like $20.
It couldn't hurt I guess.....

Would this work on a valve spring? Seems as though it would make it more brittle if anything.. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Increase resistance to abrasive wear
Requires only one permanent treatment
Changes the entire grain structure of the metal, not just the surfaces
Refinishing or regrinds do not affect permanent improvements
Eliminates thermal shock through a dry, computer controlled process
Transforms most retained austenite to hard martensite
Forms micro-fine carbide fillers to enhance carbide structures
Increases durability and wear life
Decreases residual stresses in tool steels
Decreases brittleness
Increases tensile strength, toughness and stability
Relaxes internal stresses

Re: Cryogenically Freeze Valve Springs?
I once had access to a freezer in a major university that could cool to a couple degrees kelvin. For those of you that don't know, that's only a couple degrees above absolute zero, or about -270 degrees celcius. Too bad I don't work there anymore.

Re: Cryogenically Freeze Valve Springs?
More Performance in North Carolina has cryogenic capabilities.
www.moreperformanceinc.com
To treat valvesprings it's $2.50 each spring.
I had my block and crankshaft treated there.

Re: Cryogenically Freeze Valve Springs?
should work out great.
if i where to build the engine i wanted to build, every single part would be cyro treated and polydyn'd.

PolyDyn is in Houston, and Cryo work can get done at Houston Balance and Machine. John and Tommy Costales now have a complete cryo facility.
