Many of the qualities produces require very exact-stage heat treatments to achieve the optimum physical properties fort he application for which they are intended.
Some of the treatments are lengthy, measured in a matter of weeks, and require very precise control of temperature cycles. These particular requirements are met by a dozen electrically heated, low thermal mass furnaces capable of both precise computer control and forced cooling.
The furnaces capable of both precise computer control and forced cooling. The furnaces, which are varying dimensions and loading capacity, are the latest design and technology to achieve uniform stres relieving as well as high temperature normalizing and tempering, soft annealing and air quenching.
