About Crown Cryogenic Steel
The Crown Cryogenic range are high quality turning tools with a difference. Using cryogenically treated tools means that now you can turn more and sharpen less often. The tools are made from M2 Steel that are heat treated normally then taken down to temperatures as low as -185C which changes the molecular structure of the steel.
The two main crystals in tooling steel are the larger and softer austenite and the smaller, more stable martensite. Normal heat treatment seeks to transform the austenite to martensite to produce steel with good wear characteristics and an amount of ductile properties.
The cryogenic process greatly enhances and accelerates the austenic transformation. Another benefit is that at these extreme temperatures, fine eta carbides are formed within the carbon structure. Growing very slowly and only at these very low temperatures, eta carbides are extremely small and act as a filler between the other crystals in the metal.
The combined effect of heat treatment and cryogenic processing is to produce a refined crystal structure in your hand tool that will give a lifetimes service by producing a blade that will retain its edge longer and give a superior feel in use.
All Crown Cryogenic Turning Tools are finished with beautiful black Ash handles.
