Creep Life Calculator

Estimate creep rupture life using the Larson-Miller parameter for high-temperature service of metals.

Operating temperature of the component.
°C
Applied stress at operating temperature.
MPa
From material data. Typical steel: 18000-25000. LMP = T(C + log t).
Material constant, typically 20 for most steels.
