Material property database for Grade 91 (9Cr-1Mo-V-Nb) steel. Larson-Miller creep rupture, Norton power law, tensile correlations, and Coffin-Manson strain-life from published NIMS/ORNL sources.
Creep rupture fitting tool for predicting material lifetime under high-temperature service conditions. Supports Larson-Miller and Wilshire models with confidence intervals, multi-region fitting, and stress predictions for design life (100,000+ hours).
