Heat Treatment Australia could save substantial sums of money by having Cryotemp® processing applied to your wearing or highly stressed components.

The company trademarked its process after more than 10 years of research and development of cryogenic processing techniques. Basically the process involves a unique combination of low temperature cryogenic treatment (approx. minus 73c to minus 150c) and tempering which causes retained austenite to be converted to martensite, and finer carbides to be formed in the crystal structure of an item whilst leaving it virtually stress free.

Cryotemp® is a one-time permanent treatment that affects the entire cross section of the material being treated.

This means you don’t have to sharpen cutting tools, or invest in new engine parts as often. You could dramatically reduce your consumption of perishable tools. And your service down-time could be lessened.

Tools and wearing parts could last two to five times longer than usual after undergoing the process. Cryotemp® is effective on both used and new items.

  • It lengthens work life of parts and tools. High alloy steel cutting tools stay sharp longer, with fewer micro cracks and less chipping.
  • It lowers residual stress, thus improving dimensional control in aluminium, titanium and other metals.
  • Wear resistance is enhanced in steel and cemented carbide, chromium or tin coated tools and wear parts.
  • Copper welding electrodes gain longer life. They show less wear and deformation and can be used with less power input.
  • Tip burn-off is reduced on tungsten electrodes and they carry reduced amperage.
  • It stress relieves forgings and castings to ensure dimensional stability during final machining.
  • It stress relieves metals for tear-free drawing.
  • It dimensionally stabilises components.

The size and shape of items that can be treated depends on the type of equipment operated by the heat treater. For large items, check the availability of suitably-sized facilities.

All of the following information should be included if possible. If uncertain, ask your heat treater before producing a specification:

  • The process: Cryotemp or Sub zero.
  • Material: type or grade
  • Existing condition; e.g. details of any prior heat treatment, such as hardening and tempering, solution treatment and ageing, intended to establish mechanical or other properties.
  • Requirements for any special certificates or data to be provided by your heat treater.
