Nitrider Calculation (Available on Units Configured for Nitriding & FNC Applications)
When configured for nitriding and ferritic nitrocarburizing (FNC) applications, the MGA 6010 has the
ability to provide a calculation of values essential those processes—specifically, nitriding potential (K
N
)
and carburizing potential (K
C
). To access these values, open the Nitrider Calculation page. NOTE: If the
MGA 6010 unit you are using does not have the Nitrider Calculation option, and you would like this feature
added, please contact SSi at 513-772-0060.

The Nitrider Calculation page displays data on current atmosphere parameters such as temperature and
measured values for % CO, % CO
2
, % CH
4
, and % H
2
(if the H
2
sensor is installed). The calculated value for
%C is also shown.
User-provided flow values for N
2
, NH
3
, DA, and CO
2
are used by the MGA 6010 in performing calculations.
The flow values are visible on the right side of the Nitrider Calculation page. To change a flow value,
simply tap on the blue field for that value. A numeric entry page will appear, allowing you to change the
value. For the purpose of K
N
and K
C
calculations, any valid gas flow unit (for example, cubic feet per
minute, or cfm) may be used. The flow unit must be the same for all gases. NOTE: If one or more of the
flow gases do not show up in the list, it is likely that the gas flow valve is not enabled in the Tools →
Valve Setup menu. Refer to the Valve Setup section on page 42 for more information.
K
N
provides a measurement of the amount of nitrogen that can be diffused into a metal (e.g., iron); it is a
derived measurement based on the partial pressures of NH
3
and H
2
. The MGA 6010 performs the
calculation of K
N
using user-provided flow values and displays the calculated K
N
value on the Nitrider
Calculation page.
