Material Finder: MIL-HDBK-5J Allowables at Temperature

Reverse lookup of the MIL-HDBK-5J database: enter the strength, stiffness and density you need, the basis, grain direction and operating temperature, and the tool ranks every handbook row that qualifies, with the allowables reduced by the handbook's own temperature curves. Sort by specific strength, strength, stiffness or density; each result links to the material's page with the full sheet and curves.

  • Filters on Ftu, Fty, Fcy and E (at temperature), density, class, product form, basis and grain direction

  • Allowables at temperature from the digitized handbook curves; rows without a curve are shown at room temperature and flagged

  • Ranked by specific strength Ftu/ρ, Ftu, Fty, Fcy, E/ρ or density; chart of strength against density

  • Links to each material's page and to the MIL-HDBK-5J tool
