Since Johnson Packings began performing cryogenic processing, interest in this type of treatment has grown slowly but steadily. As Mark Shortt, Editorial Director for Job Shop Technology magazine (www.jobshoptechnology.com), recently said, "Manufacturers are beginning to see how cryogenic tempering can dramatically increase the useful life of parts and tooling in a variety of materials."

For the last 4 years, customers of Johnson Packings have utilized cryogenic processing to extend the service life of end mills, drill bits, cutting blades, punches and dies, as well as to enhance the performance of sports equipment and musical instruments. Engineers are just now becoming more aware of its effectiveness in protecting against abrasive wear on steel parts and components, such as sprockets, wheels, shafts, bearings, gears and impellers.

Unlike conventional surface coatings, cryogenic treatment is a one-time process affecting the entire structure of the material. In his February, 2002 "From the Editor" column, Shortt described the process as "a 'through treatment' as opposed to a surface treatment." Reported benefits of cryogenic processing include extended part life and enhanced stress relief, resulting in less downtime for replacing broken or worn components.

The length of time it has taken for cryogenics to gain wide acceptance is probably due in large part to the difficulty in obtaining actual measurements of its effectiveness. Items that have been cryogenically treated show no physical changes that can be visually detected, such as color, size or hardness.

One company, however, has obtained some scientific documentation on cryogenic processing, commissioning the Division of Engineering Research at Louisiana Tech University to conduct a series of studies to determine what happens to materials during the process. The results of that study were also reported in the February issue of Job Shop Technology. Retained austenite in tool steels that had been slowly cooled to cryogenic temperatures was found to transform into harder martensite. The study concluded that cryogenic processing results in significant cost savings and could reduce our overall use of energy, natural resources and raw materials.

We at Johnson Packings would be glad to help you improve your parts through cryogenic processing. We are so confident that the items processed will be stronger and more wear-resistant that you will receive a full refund or credit if you don't agree.

Garlock DSA Waterless Packing is Ideal for Drought Conditions

With the drought conditions currently being experienced in the Northeast, conserving water is more important than ever. One way to do this is to use Garlock DSA Dry-Running Packing to eliminate the need for flush water in rotary service applications.

Self-adjusting Garlock DSA features the patented GRAPH-LOCK® cup and cone rings on the outboard end of the packing set. These rings expand radially to form a positive seal that drastically reduces leakage.
