An intensive water-quenching process was originated by Dr. Nikolai Kobasko of the Ukraine in early 1960s. Intensive quenching (IQ) methods and their practical applications are presented in numerous technical papers, conference proceedings and books. A recent and detailed description of IQ technology is presented in the book Intensive Quenching Systems: Engineering and Design published by ASTM in 2010.
In 1999, IQ technology was introduced to the U.S. heat-treating industry. The first production stand-alone 6,000-gallon IQ water tank was built and installed at Akron Steel Treating Co. of Akron, Ohio. Since this time, hundreds of IQ demonstrations have been conducted on test samples and actual parts made of different steel alloys. The IQ method provides the following proven benefits:
