electrical installations, electrical equipment and machinery.
Processing Techniques – Austempering
The heat-treating process for medium-to-high carbon
ferrous metals produces a metallurgical structure called Bainite. To increase strength, and toughness, and reduce
distortion. During the process that parts are heated to the hardening
temperature (between the range of 35-55 HRC), then cooled rapidly enough to a
temperature above the Martensite start temperature and held long enough to produce the desired
Bainite structure.

Advantages
Lower die costs - Less expensive to produce and
maintain than those used in other common processes.
Lower secondary costs - as cleaning and plating, are
also cheaper than similar treatments for other metal fabrication processes.
The high level of automation compared to other processes
- machines are relatively easy to automate and can employ high-end
computer-control programs that provide greater precision, faster production,
and quicker turnaround times.
Disadvantages
The higher cost of presses - The dies must be
acquired or created, and producing custom metal stamping dies is a longer
pre-production process. Dies can also be difficult to change if the design must
be altered during production.
