At the recent fall Metal
Treating Institute (MTI) meeting, Super Systems was awarded the 2009 Associate Member of the Year award. Steve Thompson was in attendance to accept the award.
This is a very important award for SSi since MTI represents the largest network of commercial heat treaters in the world.
The MTI members vote annually on this award and we feel very fortunate to have such a large group of heat treaters
express their confidence in our products and services.

Carburizing with Boost Diffuse
as featured in Industrial Heating [November
2009]
Carburizing specifications have become more
stringent requiring more precise control
during heat treating. Effective case
specifications are tight and there is a
heightened awareness rela ted to the
carbon gradient
on finished parts.
There are many
reasons influencing the tighter requirements
but years of experience along with
technology and data analysis gives
manufactures more tools to evaluate field
results and dial in required carburizing
results.
To minimize the total time to carburize
to a given case depth, processes are developed using a
boost-diffuse methodology.
The boost phase of the program is setup to introduce
a high carbon potential at a high temperature.
The high carbon potential produces a significant
buildup of carbon on the part and using the higher
temperature, it increase the activity and develops a deep
case. The diffuse step which typically immediately follows the
boost phase is a lower carbon potential and typically a
lower temperature.
This decreases the surface carbon and allows the
carbon to diffuse deeper into the part.
The combination of these processes produce a
controlled carbon gradient to deliver the correct properties
in the part.
