GNitro

Design and predict gas nitriding case depth using DANTE diffusion models.

Optimize Gas Nitriding with
Data-Driven Process Design

GNitro simulates gas nitriding to predict case depth or design a schedule that achieves user-specified targets. Using DANTE’s diffusion and nitride morphology models, it accounts for nitrogen potential, furnace conditions, surface geometry, and alloy variation to generate reliable nitrogen profiles.

Precision Gas Nitriding Design and Prediction

Predict nitrogen and hardness profiles from a user-defined nitriding schedule (step time, temperature, nitrogen potential).
Design a schedule to reach a specified effective case depth (ECD), nitrogen level at ECD, and total number of steps.

Material Modeling and Alloy Variation

The software uses the DANTE material database, including diffusion models and nitride morphology behavior. It accounts for base nitrogen, base carbon, and alloy variations from nominal composition.

Geometry & Process Controls

Supports curved and flat surfaces
Unit selection for temperature, time, and dimensions
Gas Type Factor represents different nitriding gas mixtures

Flexible Process Definition

In Prediction mode, users input the nitriding schedule directly.
In Design mode, users specify furnace roundup time and target results, and GNitro calculates the time required to meet the final step’s ECD.

Outputs Capabilities

GNitro outputs nitrogen profiles by depth and total processing time required for the designed schedule, enabling evaluation and optimization of nitriding performance.
