Mechanical Properties

Condition	Hot worked, as hot worked	Cold and hot worked, annealed	Forging quality
Tensile Strength, min, ksi [MPa]	80 [550]	75 [515]	Note B
Yield Strength, min, ksi [MPa]	35 [240]	30 [205]	Note B
Elongation in 2 in. [50mm] or 4D, min, %	25 [Note A]	30	Note B

Notes:

A: For hot-worked as-hot-worked rectangular bar 5⁄16 in. (7.94 mm) and under in thickness the elongation shall be 20 % min.

B: Forging quality is furnished to chemical requirements and surface inspection only. No tensile properties are required.
