I've seen this process done on 4x4 differentials and they couldn't be broken. Basically it lines up the molecules in the metal and locks them together for a dramatic increase in strength. It changes the metal from Austenite (a fragmented dissary of carbon molecules formed in the quenching process) to Martensite, which alignes the carbon molecules in one direction and interlocks them in the process for an increase in strength of 30% - 50 %.

Now, I'm no genious, but starting at $2.50 per component, its probably worth sending out your internals to be treated.

good find, worth considering...

Thank you, sir. I think this could open some doors in terms of hot-rodding this engine. The crank bearing could become a non-issue, Chanito's head blots would be twice as strong as stock, increased valve spring rate...etc.

stronger = more brittle?

hmm... chanito bolts twice as strong as stock? hmm...

1) i am almost ready to do the big bore.

2) timber, jump on this shit! spend all your money strengthening your parts! but we all will laugh when even cryoed big bore cylinder will freeze without oil one more time...

stronger does = more brittle. Austenite is non-magnetic, by changing the austenite into martensite its true you will increase the life of the parts in terms of wear but you will dramatically shorten their life due to the cracks that will form because you just made the thing really brittle. I think theyre just describing carburizing followed by case hardening. You can get that done anywhere nothing special.

you could call this a type of heat treatment, very low temp...

but how cyro treatment works is they bring the parts down to -xxx degrees and let is slowly rise back up to room temp...think it was a few degrees an hour

yeah, stronger = more brittle, not as strong = more ductile.... simple materials stuff... blah blah....

so when your bolts fail it will be a catastrophic failure instead of a slow bending/twisting failure....

You want a ductile failure on things like axel bolts etc... because a instantaneous snap = death basically...

How did we get to stronger = weaker? Maybe if you were using the ruckus engine as an anvil? 300 HP mashing on a locked Dana 44 under a 4,000 lb jeep on Moab's terrain can't damage a treated differential (Four Wheeler May, 2007 vol 44, no.5), but a rucks engine will fail? C'mon guys, this process doesn't turn the parts to ice! It is simply a quenching process that ensures the best results rather than being quenched using the cheapest possible means. The process increases durability, resistance to wear and fatigue by 100%. Increases in strength (impact) of 30 to 50%. Engine rebuilds last twice as long due to thre fact the treated parts have an increased ability to dissapate heat as well, and transmissions run as much as 50% cooler. Anyways, what do I know? As with most ruckus topics, let the debate rage on...

Nothing comes for free. If cryotreatment really turned ordinary steel into supermetal, Honda would have used thinner and/or lower grade metal for the engine block and just cryotreated it at the factory.

As far as the demonstration - 4x4 diff casings rarely fail anyway, it's the internals and shafts that break first 99% of the time. Even when a diff does fail, it's nearly always because a piece of broken gear or carrier shoots through it at high velocity.

There are definite places for cryotreatment IMHO, it's just not a magical way to make any steel part 10x better.

1. Raw metal is cheaper than cryogenic treatment.
2. Casings? It was gears, a D44.
3. 50% is not 10x better
4. I'm changing my signature.

I'm with ya...Don't know much about it, but you always speak (IMHO) from experience.

And hell, you are always going out on a limb to find performance upgrades...IMO, drive is more important than anything.

it sounds like a great idea... you do it first. but, let me say this, it's a great process but i wouldn't do it to one of my swords because i think it would make them more brittle and subject to breaking(shattering). High carbon spring steel needs to be flexable. I'd most likely send in my armour to get this treatment because of the strenght benifit. I wonder if this works on chain maille?
