It can have a profound effect on the mechanical properties of certain steels, provided their composition and prior heat treatment are such that they retain some austenite at room temperature. The computer controlled vapor cryogenic process involves an 8 hour rampdown from ambient temperature to -310°F, “soak” or hold at -310°F for 10 hours, and a rampup to ambient temperature of at least 24 hours. There is evidence, however, that cryogenic treatment of steel, in which material is brought to a temperature of the order of -190°C (-310°F), improves certain properties beyond the improvement attained at cold treatment temperatures. ISF® stands for Isotropic Superfinish. These desirable changes are why many knife and sword makers use this process as it gives metal a more uniform hardness and greater … 1. About DCT. However, the process has evolved and is computer-controlled at a slow speed now. For that reason, cryogenic treatment is performed using computer-controlled temperature changes. Manta has 1 companies under Cryogenic Treatment of Metal in Indiana. “I recommend it for those makers using complex steels, and I’m only charged a small amount for the blades I send for cryo treating,” Beaty noted. It is common to Cryo tooling used in the metal working industry. Blade Magazine Cutlery Hall-Of-Fame© member Paul Bos began heat treating knife blades in the 1950s. A2 and D2, as well as other high-alloyed tool and specialty steels, may contain as much as 20 percent austenite after normal heat treating. Caribou Media Group earns a commission from qualifying purchases. “Cryogenic treatments should always be followed by tempering. Austenite makes steel brittle, and under a microscope you can see what looks like little clumps of carbon. I always get a big difference, probably a 40-to-50-percent difference in edge-holding capability, as the cryogenic quench refines the grain of the steel.”. Forum: Search: FAQs: Links: MVPs : Menu. Whether called cryogenic quenching or the probably more correct cryogenic treating of the steel, the process of freeze treating to help make a steel the best performer it can be is nothing new. thread330-151671.

The slow cooling process from ambient to cryogenic temperatures is important in avoiding thermal stress. In cryogenic treatment materials are treated at -196°C for a soaking period of 24 hours. A cube with 14 atoms, one in each corner and one in the center of each face of the cube, is face-centered cubic (FCC). To obtain the maximum formation of martensite, two or more complete tempering cycles are necessary following the sub-zero cryogenic quench. It’s used after the quench in an effort to achieve more complete transformation of austenite to martensite [martensite being the hardest of the transformation products of austenite]. Anodized surfaces, or metals such as aluminum, also obtain longer life. However, the process is specialized and requires close attention to actual temperature, levels of exposure, and the time intervals involved in raising and lowering the temperatures of the steel itself. Cold treating of steel is widely accepted within the metallurgical profession as a supplemental treatment that can be used to enhance the transformation of austenite to martensite and to improve stress relief of castings and machined parts.

It doesn’t treat any cancer cells in other parts of the body. Home. Cryotherapy is also used as a method of treating localized areas of some cancers (called cryosurgery), such as prostate cancer and to treat abnormal skin cells by dermatologists. Bos does a snap temper on high-carbon tool steel and then the cryogenic process at -280°F for about eight hours, and then brings the steel slowly back up to room temperature before a second temper. First, he writes, “Super cold treatment seems to convert retained austenite structures in the metal into martensite, which is very hard and brittle. Cryotherapy to treat tissue located inside the body requires image guidance and a cryotherapy applicator or cryoprobe, a thin wand-like device with a handle or trigger or a series of small needles. Our proprietary cryo processing optimizes the crystalline structure of steel, gray iron, aluminum, and other metal and plastics. This treatment is performed by slowly cooling the parts in a controlled bath of liquid nitrogen or other refrigerant, and holding the parts until the temperature has reached the target temperature, then returning the part to room temperature. Effect of Cryogenic Treatment of Metal. Localized treatments include the application of ice or gel packs, ice massage, or cryotherapy machines (for post-op) for 20 to 30 minutes at a time, several times per day, especially after physical therapy or exercise. I have read this in … Cryogenic Processing Machines. Cryogenic metal treatment is perfect for industrial applications where durability directly impacts the bottom line.

The camshaft is also a high wear area of a performance tuned engine and will benefit from Cryo treatment. Localized cold therapy affects the superficial tissues as soon as 5 minutes after application. Table 2. In the shallow treatment, the blade steel is brought to approximately -112°F for five hours, while in the deep treatment it is reduced to roughly -321°F for about 35 hours. Featured Company Listings. Since the U.S. military became involved in cryogenically quenching steels during World War II and required it in the manufacture of various defense-related products, several methods have been evaluated with the same goal in mind: optimizing the amount of martensitic iron in the structure of the steel while minimizing the residual amount of austenitic iron. And lastly, do I need to cryo treat between each temper cycle? The so-called cryogenic treatment is to use liquid nitrogen (-196 ° C) as a cooling medium to continue the cooling process of the quenched metal material to a temperature far below room temperature, which promotes the acquisition of residual austenite after conventional heat treatment. Cryogenic treatment is not a different type of quenching method but is an additional treatment normally used after quenching.
