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

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

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.

METALLURGICAL CHANGES IN STEELS DUE TO CRYOGENIC PROCESSING & ITS APPLICATIONS

Metallurgical changes in steels due to cryogenic
processing & its applications

Abstract:
Cryogenic processing is a supplementary process to conventional heat treatment process in steels. It is an inexpensive one time permanent treatment affecting the entire section of the component unlike coatings. Though the benefits have been reported widely, there are issues debated upon, in respect of the treatment parameters, extent of benefits exp ....etc

stainless steels


What are stainless steels

Alloys of iron, chromium and other elements that resist corrosion in many environments
A minimum of 12% Cr is required for it to be a stainless steel

Ferritic stainless steels

Have a BCC ferrite microstructure
Low carbon contents (<0.2%)
Cr in the range 12-20%
They remain ferritic all the way up to melting point
Poor weldability
Extra low interstitial grades developed with improved weldability

Martensitic stain ....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
