I have heardthings about cryo treating metal. Here is a short explanation of each.

1. Cryo/According to Steve Klingbiel, One Cryo, Orlando, Florida, “The process entails taking steel, or sometimes aluminum or titanium parts, very slowly down from room temperature to –300 degrees below zero, roughly at about one degree per minute. At that point, about 12 hours later, we begin a hold cycle, which is normally from 24 to 36 hours, also at 300 below. At the end of that period, we slowly warm the parts back up to room temperature, again at about one degree per minute. Then we perform a triple heat temper, from 275 to 375 degrees in three different heat and cooling cycles. This process will realign the molecules so they become more uniform, relieve the stress, and the surfaces will actually be smoother.”

2. Vibration/ The system uses low frequency, high amplitude vibrations to reduce the residual stress level to a point where it cannot cause distortion or other problems, Fischer explained. A vibration generator is either clamped to the work-piece, attached to the tooling fixture or fixed to SRE’s “ Loadmaster 2000” vibration table. The vibration level is then adjusted to produce the desired amplitude, and sine waves pass through the parts, relaxing the microstructure. The treatment lasts between 15 and 30 minutes, depending on the size and weight of the work-piece.
One beneficiary of the process has been valve springs, Fischer said. “Another direct beneficiary has been our own sprint cars. Once the residual stress energy in the chassis has been dissipated, there is little chance that the chassis will suffer from random distortion once it’s placed in service, or that it will become difficult to tune and adjust. Sprint car chassis are not known for their long life- once they’ve been in a crash, they usually won’t square up the same way when making chassis adjustments.”

The reason I ask is that I am going to be building a motor starting next week and would like some of the benefits mentioned.

 

well there is a lot of debate about the tech used and whether it actually works. Heres the thing, are you going with aftermarket rods or are you going with stock. Well the thing is with aftermarket depending on who you go with they use a lot of different metals, some use good **** other use metals that have a lot pores. The entire idea od nodularly spining metals at the point of production effectively conteracts all the benefits of cryo. All the porous denser metal is shaved off only leaving the lighter and metal that has less pores and is overall a lot better. A good rod that not many people use is the SEANZ and the ULTRALIGHT rods. Ross pistons blah blah blah...... There s a million setups but just ask the manufac of the product your buying how the metal is treated and produced. hope i helped... probably not

 

I was thinking of doing the whole block once it's sleeved at golden eagle and then crank and head. The use aftermarket pistons/rods. I'm wondering how the sleeves would react when cooled compared to the alluminum in the block casting. The sleeves are welded into the block I think. Dissimilar metals might cause problems or maybe it would just make the welds more stable??

 

It would void the warranty i think.

 

Maybe I should do it before i send it to them then. I didn't know GE had a warranty. Their website sucks right now. I will have to call them.

 

no just get the nodular spun wound sleeves everything else is more then fine. Your just going to be spending a lot of money for nothing. It s not like where f1 cars here u know. good luck
