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.

Strength allowables at temperature, percent of room temperature
