A. Yield strength requirements do not apply to material under 0.020 in. (0.51 mm) in thickness.
B. For Rockwell or equivalent hardness conversions, see Hardness Conversion Tables E 140.
C. Caution should be served in using the Rockwell test on thin material, as the results may be affected by specimen thickness. For thicknesses under 0.050 in. (1.3 mm),
the use of the Rockwell superficial or the Vickers hardness test is suggested.
D. As-rolled plate may be given a stress relieving heat treatment subsequent to final rolling.
E. As-rolled plate specified “suitable for hot forming” shall be furnished from heats of known good hot-malleability characteristics. There are no applicable
tensile or hardness requirements for such material.
F. Annealed at 1850°F (1010°C) minimum.
G. Not applicable for thickness under 0.010 in. (0.25 mm).

A. For Rockwell or equivalent hardness conversions, see Hardness Conversion
Tables E 140.
B. Caution should be observed in using the Rockwell test on thin material, as the
results may be affected by specimen thickness. For thicknesses under 0.050 in.
(1.3 mm), the use of the Rockwell superficial or the Vickers hardness test is
suggested.
C. Sheet requirements (above) apply to strip thicknessess over 0.125 in. (3.2
mm), and for all thicknessess of strip over 12 in. (305 mm) in width.
D. For ductility evaluations for strip under 0.005 in. (0.13 mm) in thickness, the
springback test, such as described in Test Method F 155, is often used and the
manufacturer should be consulted.
E. Accurate grain size and hardness determinations are difficult to make on strip
under 0.005 in. (0.13 mm) in thickness and are not recommended.
