What is cryogenic heat treatment?
Cryogenic heat treatment is the ultra low temperature processing of materials to enhance their desired metallurgical and structural properties
The temperature is about -196 C or 77 K
Ultra cold temperatures are achieved using computer controls, a well-insulated treatment chamber and liquid nitrogen (LN2)
They are completely environmentally friendly and actually help reduce waste

The process is capable of treatin ....etc

cryogenic treatment of brake rotors ppt

Cryogenic Treated Rotors

For drivers who need something even tougher than a standard StopTech Sport rotor, but are not ready for a big brake kit, StopTech offers cryogenically treated Cryo rotors. Cryogenic treatment is a one-time stress relief process that involves both cold and heat cycling of the brake rotor. Using a proprietary computer-controlled process over a 24-hour period, the cryo machine gradually cools the rotors down to -300 F, then gradually brings them up to over +300 F, and finall ....etc

A cryogenic treatment is the process of treating workpieces at cryogenic temperatures (ie below -190 C) in order to eliminate residual stresses and improve the wear resistance of steels. In addition to seeking improved stress relief and stabilization or wear resistance, cryogenic treatment is also sought for its ability to improve corrosion resistance by precipitating micro-fine eta carbures, which can be measured before and after in one part using a quantimet.
The process has a wide range of applications from industrial tools to improving th ....etc

Improving component wear performance through cryogenic treatment
Controlling machine wear is a fundamental function of lubrication. By properly specifying lubricant viscosity, using appropriate modifying additives, and controlling contamination, wear rates can be
minimized to extend equipment life. Cryogenic treatment of tooling steels is a proven technology to increase wear resistance and extend
intervals between component replacements for blades, bits, and machining mills. Recent studies have been conducted on the effects of cryoge ....etc

A cryogenic treatment is the process of treating workpieces to cryogenic temperatures (i.e. below 190 C ( 310 F)) in order to remove residual stresses and improve wear resistance on steels. In addition to seeking enhanced stress relief and stabilization, or wear resistance, cryogenic treatment is also sought for its ability to improve corrosion resistance by precipitating micro-fine eta carbides, which can be measured before and after in a part using a quantimet.

Introduction

This study is motivated by a real problem at the Alang ship-dismantling facility near Bhavnagar in Gujarat. The focus of this study is the paint chip waste which is generated in ship breaking activity. Alang, located 56 Km away from Bhavnagar city in Gujarat, came up as ship breaking site during 1982-83. Hundreds of old ships, after their useful life, are broken at the Alang ship breaking yards without any precaution to protect the environment. Ship breaking and its harmful consequ ....etc
