Increase the life of tools, equipment, parts and material components. Cryogenic tempering boosts tensile strength, toughness and dimensional stability.
The Cryogenic Tempering Process
Any material may be cryogenically treated. The transformation of retained austenite into martensite will improve the tensile strength and hardness of the material. Carbide precipitates that form within the martensitic structure are responsible for the improvement in wear resistance. Dimensional stability is improved with cryogenic treatment that removes the kinetic energy of atoms; the energy of motion. Tempering may also be applied for stress relief of castings and machined parts. Non-ferrous alloys including aluminum, magnesium, titanium, copper, nickel alloys, plastics and nylon may be treated as well.
Cryogenic Treatment
The cryogenic tempering and freezing treatment increases the life of tools, equipment, parts and materials by boosting tensile strength, toughness and stability. This computer-controlled process is a one-time treatment affecting the entire component and not just the surface. Our gas fired oven facilities are located in Calgary for Heat Treating of Vessels and Process Pipe Spooling.
Heat Treating Steel
Integrated Metallurgical Services Ltd. Is a Canadian owned and operated company based in Calgary, Alberta, Canada and specialising in the Heat Treating of metals.
This company is a young, dynamic company with the sincere objective of providing and maintaining a high degree of service and quality workmanship to keep pace with the ever-demanding advances in technology as it pertains to heat treating steel. Our equipment is among the finest and most modern of any available in the Heat Treating Field and we are proud of its reliability, accuracy and ability to meet the most demanding of standards and specifications.
With the ever-increasing demand for better, safer and more reliable products, we recognise the need for a rigidly controlled program to acquire and maintain personnel with a broader technical knowledge in this field. This area is continually under critical review by Integrated for the advancement and betterment of heat treating steel.
Deep Cryogenic Tempering
What is deep cryogenic tempering? It is a computer-controlled process. The system comes with proven processing cooling curves programmed into the computer. Any other desired cooling curves may be easily programmed into the processor. Deep cryogenic tempering is a dry process. Liquid nitrogen is converted to a gas before it enters the chamber so that at no time does liquid nitrogen come in to contact with the parts assuring that the dangers of cracking from too rapid cooling are eliminated.
Deep cryogenic tempering treatment is a dry process and requires temperatures of -300° F degrees or lower. There is no exposure to cryogenic liquids, thereby eliminating the risk of thermal shock. Items are cooled slowly (less than 1° per minute). Low temperature is held from 20 to 60 hours. Items are tempered if required.
* Note: We temper afterwards because the cryogenic treatment has a detrimental affect on the fracture toughness (impact properties). Heating the item brings the fracture toughness back to its original state.
