The ISF Process produces a slightly oxidizing environment in the vibratory equipment and hydrogen is not generated. ISF has been repeatedly tested and proven to be free from causing hydrogen embrittlement and intragranular attack. The process is metallurgically safe.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

No. The ISF Process has been certified for use on DIN 2 (AGMA Q 13) quality gears. Material refined from the surfaces of gear flanks is uniform in profile and from tooth to tooth. Depth of material removed by the ISF Process is typically 0.0001inches.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

No, the cryogenic process is a one-time, permanent treatment affecting the entire object. It is not a surface coating. The item is chilled to -300 degrees Fahrenheit using a dry nitrogen atmosphere. This has an effect on the entire thru the grain structure of the part.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tNo. Our process is completely dry. Parts never come in contact with liquid. The LN2 evaporates and cools the chamber and is circulated internally by a fan.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tNo, it is not necessary. Tools may be processed sharp or dull. And since cryogenics is a one-time treatment affecting the part to the core, you can re-sharpen the tool as many times as necessary without having to re-cryogenically treat the part. Therefore, you may wish to treat new tools or tools that have not been worn excessively to obtain the maximum amount of life for the least amount of cost.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tYes, absolutely. In fact, a treated part or blade will not only last longer, it will also obtain and hold a superfine edge not normally achievable prior to treatment.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tNo. There is no significant increase in the hardness of treated parts. Some metals may see 1 or 2 points of increase on the Rockwell scale. More importantly, though, the part becomes more uniform and the hardness becomes consistent throughout the part.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Cryogenics is not the answer to everything, but it is very effective on all steels, alloys, and other metals as well as carbon fiber, kevlar, some plastics and polymers. Electronics is also on the list. Many other materials are under experimentation and still others have yet to be considered. If you have an application in mind, let us know. We are constantly trying new things and would be happy to test new products with you.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
