HTP Sim

Simulate complete heat-treat cycles with fast, accurate, easy-to-use process modeling.

End-to-End Heat Treatment Process Simulation Made Simple

HTP Sim models the entire heat-treating process, from heating and carburizing to quenching, freezing, tempering, and beyond. Built on the same validated metallurgical models used in DANTE FEA, HTP Sim provides fast, reliable predictions of hardness, phase transformations, and carbon/nitrogen diffusion, with simplified setup and no meshing required.

Heat Treatment Simulation for Process Engineers

HTP Sim is an advanced heat treatment simulation tool designed for quick, accurate modeling of thermal and diffusion-related processes. It enables engineers, metallurgists, and heat treaters to predict how heating, cooling, carburizing, nitriding, and other process steps affect hardness, microstructure, and carbon/nitrogen profiles, without requiring a full finite element analysis.

Using the same validated transformation kinetics and diffusion models found in the DANTE FEA package, HTP Sim delivers a powerful balance of accuracy and ease of use, ideal for process planning, optimization, troubleshooting, and education.

Process Simulation Capabilities

HTP Sim can model a wide range of heat-treating operations, including:

Heating and furnace soak time estimation
Carburizing and nitriding (Boost/Diffuse schedules, case depth prediction)
Quenching (oil, polymer, water, gas quench severity effects)
Hardness and phase transformation prediction during cooling
Deep freeze (cryogenic treatment)
Tempering
Precipitation hardening

Multi-step process sequences from start to finish

This versatility makes HTP Sim a complete process modeling tool for both simple and complex heat-treat cycles.

Simplified Setup with Powerful Material Model

Uses the same validated phase transformation, diffusion, and carbide/nitride morphology models as the DANTE FEA suite
Part geometry is reduced to an equivalent section size, removing the time-intensive need to create or mesh geometries
Furnace, quench tank, or equipment options are selectable from a menu, eliminating manual boundary condition setup
Ideal for fast iteration and concept validation

Outputs

HTP Sim provides time-based and section-based predictions, including:

Hardness evolution
Metallurgical phase fractions (martensite, bainite, ferrite, pearlite, retained austenite)
Carbon and nitrogen profiles over depth
Cross-sectional hardness or carbon distribution
Single-point thermal and microstructural histories through the full process

These outputs help engineers evaluate process sensitivity, optimize parameters, and troubleshoot production issues before running expensive trials.

Applications

Designing and validating heat-treat schedules
Optimizing quench severity or furnace cycle times
Predicting case depth for carburizing/nitriding
Comparing material chemistries or section thicknesses
Educating heat treaters and students on metallurgical behavior
Supporting DANTE FEA workflows with pre-validated process data
