| description.abstract | Cryo-processing, a supplementary process to conventional heat treatment, involves freezing of
materials at cryogenic temperatures to enhance the mechanical and physical properties of
materials. This paper deals with improvement of properties of the tool steel by cryogenic
treatment and its greater life span in an industrial application. After the Second World War
cryogenic technology were abandoned until the seventies when aerospace industry took up this
technology again and the treatment started to be developed as a new industrial process. Today
cryogenic treatment would be regarded as one of the most important processes in the field of
industries, and it is the ultra modern type of processing to make the metals more resistant to wear
and more durable. The use of this treatment is extremely environmentally friendly and absolutely
produces no waste during the process. The properties of the cryogenic treated tool steel are
generally gained due to the conversion of austenite to martensite. Proper heat treating can
transform 85% of the retained austenite to martensite and the cryogenic treatment only
transforms an addition of 8 to 15%. Present investigation is about cost and durability after and
before cryogenic treatments. As it is known the most important problems faced by the industries
are the wear and tear of the machine parts. This wear of the machine parts not only increases the
cost of production but also the time wasted for the replacement process. Cryogenic technique
gives assurance for solve these problem. These ultra-cold temperatures, below -310°F, will
greatly increase the strength and wear life of all types of vehicle components, castings and
cutting tools. In addition, other benefits include reduced maintenance, repairs and replacement of tools and components, reduced vibrations, rapid and more uniform heat dissipation, and improved conductivity. | en |
