Design Mechanical and Physical Properties (room temperature)

Converted from the handbook table (ksi, Msi, lb/in³) and rounded to 4 significant figures; dimension bands in inches with mm in parentheses. Bases: A and B are statistical minimums (99 % and 90 % probability at 95 % confidence), S the specification minimum. Grain directions: L longitudinal, LT long transverse, ST short transverse.

Effect of Temperature

Percent of the room-temperature value against temperature, digitized from the handbook figures (the shortest exposure of each figure, every 10 °F). Strength curves give the allowable at temperature; "after exposure" curves give the room-temperature property after a soak at that temperature.

Stress-Strain Curves (Ramberg-Osgood)

ε = σ/E + 0.002 (σ/F_y)^n with the first band's A-basis yield strength and the exponent on file for it (the tension curve stops at F_tu).
