Nitriding Cost at 110% nitriding cost capture: a worked example

What does the result look like when nitriding cost capture reaches 110%? The full calculation is worked below with real intermediate numbers. Use it when gas nitriding, plasma nitriding, ferritic nitrocarburizing, or case hardening work needs a clear cost basis.

The inputs for this scenario

  • Nitrided parts or area units: 120 units (unchanged)
  • Nitriding cost rate: 12 $ / unit (unchanged)
  • Nitriding cost capture: 110 % (raised for this scenario; the documented default is 100)
  • Fixed masking or certification cost: 400 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Captured nitriding cost = nitrided parts or area units × nitriding cost rate × nitriding cost capture) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,984 $ for total nitriding cost, the number this scenario is built around.
  • At this operating point the engine returns 16.53 $ / piece for nitriding cost per unit.
  • At this operating point the engine returns 1,584 $ for captured nitriding cost.
  • At this operating point the engine returns 400 $ for fixed masking or certification cost.

How this compares with the baseline

  • Against the tool's baseline example, where nitriding cost capture sits at 100% and the headline result is 1,840 $, this scenario comes in 7.83% above the baseline at 1,984 $.
  • A figure at this level is achievable when nitriding cost capture is genuinely sustained, not just peaked for a shift. The rate is treated as flat per unit, so it does not by itself reward better furnace packing; if you double the parts in a load the model assumes the same per-unit rate even though real cycle cost is largely fixed by furnace hours.
