No, we don't send your parts to the moon! We place them in a processor where they are gradually cooled with nitrogen gas to -300 degrees Fahrenheit. That temperature is maintained for at least eight hours. The length of time varies by material and desired results. After the cooling cycle is complete, the item is slowly warmed back to room temperature. Then the object is heat-treated, with temperatures of 100 to 400 degrees Fahrenheit, depending on the composition of the item. Finally, the item is gradually returned to room temperature. The complete process takes a minimum of 24 hours. What is actually happening to the object? This one-time process tightens grain structure creating a denser microstructure while increasing surface area. This improves the path of energy and provides increased stress relief and dimensional stability. The bottom line components last longer and perform better. *NOTE: There is a $1000 core charge for this performance package.
This is an Oversized item and needs to be shipped by truck freight. We suggest it be shipped directly to the shop installing it. Your order will be adjusted to actual shipping costs. |
