How to Use This Calculator

Enter the Service Temperature (°C) at which the component operates.
Input the Applied Stress (MPa) on the component.
Set the Rupture LMP (×10³) from the material's Larson-Miller rupture data curve.
Enter the LMP Constant (C) — typically 20 for steels (from material data sheets).
Read Predicted Rupture Life (hours) and Safety Factor to evaluate service life margins.
