>"Using industrial Induction-Heat and Water-Quench equipment configured and tuned for Flash® processing parameters, the steel is rapidly heated (2-3 seconds) to temperatures of about 1070C to 1200C. Within a few seconds, the heated steel is quenched with a water spray or bath. By limiting heating time, the natural heterogeneity of the steel is preserved to create a highly complex, multi-phase, multi-chemistry steel that combines the ductility of bainite and the strength of martensite." This process (creating strength in the steel) might be the opposite of annealing; that is, the opposite of allowing a magnetic substance long amounts of time for a slow, very gradual, incremental cool-down (which also apparently increases ductility -- but reduces hardness...)
