Hardening Methods
HARDENING (up to 2250°F)
Hardening via water-quench, oil-quench, forced- or still-air quench, or aging results in improved mechanical properties, hardness, and toughness of the alloy material.
Intensive Quenching:
About 35 years ago, Dr. Nikolai Kobasko of the Ukraine discovered the "intensive quenching" phenomenon for heat treatment of steel parts. Intensive quenching is defined as very rapid cooling, usually with pure water quenchant, at a rate several times higher than the rate of "normal" or conventional quenching, continuing through the martensite phase. In contrast to common quenching practices, Dr. Kobasko's research shows that very fast and very uniform cooling actually reduces the probability of part cracking and distortion, while improving the surface hardness and durability of steel parts.
Since his discovery, Dr. Kobasko and his colleagues conducted hundreds of laboratory and field validation experiments. They developed computer models for intensive quenching technology and applied the technology to many production heat-treating plants in countries of the former Soviet Union as well as China and Bulgaria. Dr. Kobasko and his colleagues chronicle the proven benefits of intensive quenching in over 150 technical papers. Since 1998, Akron Steel Treating Company of Akron, OH, USA has conducted hundreds of experiments with a variety of steel parts proving the effectiveness of the intensive quenching technique, known as IntensiQuench(SM)process. A detailed description of the IntensiQuench(SM) technology is presented in technical papers.
With IntensiQuench(SM) processes, heat-treating will never be the same.
This technology offers a proven design tool for implementing the technology for a wide variety of steel and with varied part geometry. Examples from technical papers are summarized here:

Steel part Type of Steel Lifecycle Improvement
Truck half-axles 4340 (oil quench); AISI 1045 (intensive quench) 760%
Shaft 81B40 (oil quench); AISI 1045 (intensive quench) 800%
Concrete Breaker Point 4340 (oil quench); AISI 1078 (intensive quench) From 1 hour (in oil) to no failure
Punches High Speed Steel 50-100%
Dies AISI 52100 50-100%

Intensive quenching provides significant part lifecycle improvement due to improved mechanical properties and the presence of beneficial compressive stresses on the surface of the parts. The lifetime of the intensively quenched parts made of plain carbon steel proved to be 50% - 800% longer than parts made of alloy steel and quenched in oil.
Advantages of Intensive Quenching
Commercial heat treaters will benefit from the following IntensiQuench(SM) process benefits:

  • Minimizes part cracking and scrap
  • Minimizes part distortion (less grinding and post-machining operations-saving thousands of manufacturing dollars)
  • Uses less costly, environmentally friendly quenchant (usually plain water) instead of hazardous oil, resulting in the significant reduction of the heat treatment costs and related pollution
  • Additional cost savings from less environmental waste, waste steam management, cleaner plant, cleaner parts, lower insurance, better work environment, etc.
  • Achieves the greater productivity of the quenching equipment since IntensiQuench(SM) processes provide much faster cooling rate
  • The pollution free quench facilitates the integration of heat treating into manufacturing cells
In addition to the benefits to commercial heat treaters, part designers and captive heat treaters will benefit from the following:

  • Increases the depth of hardness
  • Achieves the same or better metallurgical properties while using lower alloy steel resulting in significant cost savings in material.
  • Smaller, lighter IntensiQuench(SM) parts can do the work of heavier sectioned oil-quenched parts.
  • Provides an optimum combination of high compressive stress on the surface and a high-strength, wear-resistant, fully quenched layer of optimum depth, or a relatively soft, but properly strengthened core-all resulting in longer part life at a lower cost.
Heat treating equipment manufacturers will benefit by expanding their business to manufacturing pollution free quenching equipment for their customers and incorporating IntensiQuench(SM) computer modeling into their designs.
