Steel Hardenability (Jominy End-Quench) Calculator

Predict hardness at Jominy distance from alloy composition using empirical correlations (Just's equations). Determine through-hardening diameter for quenching in water, oil, or air.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Predict hardness at Jominy distance from alloy composition using empirical correlations (Just's equations). Determine through-hardening diameter for quenching in water, oil, or air

Each component has a specific meaning:

  • Alloy composition — The alloy composition recorded for the scenario being assessed.

Note: Interpret the jominy hardenability result against the thresholds and context described above.

How to Use

Enter the alloy composition for the scenario you are assessing. Predict hardness at Jominy distance from alloy composition using empirical correlations (Just's equations). Determine through-hardening diameter for quenching in water, oil, or air. Use the jominy hardenability result to inform your calculation.
