Heat-Treatment
Heat treatment is a method used to alter the physical, and sometimes chemical properties of a material. The most common application is metallurgy.
It involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material.
It applies that Heat, Hold, Quench that is nothing but HHQ.
Intensive Quench System (IQS)
An alternative method for the hardening of steel parts has been developed as a means of providing steel products with superior mechanical properties.
This processing method, termed as "Intensive Quenching," imparts high residual compressive stresses on the steel surface, thus allowing for the use of lower alloy steels, reduction or elimination of the need for carburization and shot peening, and providing for more cost-effective heat treating.
Benefits of IQS
Increases the depth of hardness.
Eliminates surface cracking.
Minimizes part distortion.
Achieves the same or better metallurgical properties while using lower alloy, less costly steel.
Provides an optimum combination of high surface compressive stress; high-strength, wear-resistant quenched layer; and relatively soft but properly strengthened core resulting in longer part life.
Uses less costly, environmentally friendly quenchant (usually plain water), instead of expensive, hazardous oil.
Shortens the duration, or fully eliminates, the carburizing cycle.
Achieves the greater productivity of the quenching equipment due to much faster cooling rate.
Application of Intensive Quench System
Aerospace industries (engine turbine blades, landing gears, transmission)
Automotive industries (transmission components, fuel injectors)
Agricultural industries
Weapon industries
Dies and Punch industries
Conclusion
“Innovation is path to Success and Success does not comes out without hurdles”
