What is the IntensiQuench® Process?
|
|
IntensiQuench® is an environmentally friendly, multi-step quenching technique for the heat treatment of steel parts.The first step is very rapid and uniform cooling from the austenitizing temperature, usually in highly agitated water, until optimal compressive stresses are attained in the surface layer of the part. Once optimal compressive surface stresses are attained, the part is removed from the quench, and the final cooling step is done in air or inert gas. In contrast to conventional oil, polymer/water or gas quenching, IntensiQuench® methods provide higher as-quenched hardness, to a deeper level in the part, while maintaining high residual compressive surface stresses, and, at the same time yielding low distortion.

Why Does the IntensiQuench® Process Work?

IntensiQuench® “Know How”
|
|
The key element of the patented IntensiQuench® process is to interrupt “intensive” water cooling when the compressive stresses on the part’s surface are at their maximum value. The IQ Technologies’ “know how” includes software packages and real life data-bases for calculating the proper cooling recipes for various alloys and for parts of different shapes and types.

|
Due to very fast and very uniform cooling in the first step of the Intensi-Quench® process, the entire part surface reaches the martensite transformation region at the same time regardless of the part geometry and thickness variation. Therefore, the hardened martensitic structure starts forming in a matter of seconds simultaneously throughout the whole part surface area creating a firm case or shell with high compressive stresses on the part surface.
|
|
|
|
|
This compressive case acts as a “die” holding the part and minimizing distortion. After tempering, part toughness and fatigue life are improved over conventional quenching methods. The result is a SupR-STRONG™ part with little part distortion.

IntensiQuench® Process Proven Benefits:
|
- 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.
