Note :
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 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.
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 (see X1.2.2). There are no applicable
tensile or hardness requirements for such material.
F. Sheet and strip 0.010 to 0.049 in. (0.25 to 1.2 mm), inclusive, in thickness shall have an elongation of 30 % minimum. Sheet and strip 0.050 to 0.109 in. (1.3 to 2.7
mm), inclusive, in thickness shall have an elongation of 35 % minimum.
G. Not applicable for thickness under 0.010 in. (0.25 mm).

Note:
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. There are no applicable grain size requirements for low-carbon nickel (UNS N02201) sheet. The hardness of low-carbon nickel (UNS N02201) sheet shall be not over
Rockwell B64, or equivalent.
D. Sheet requirements in Table 4 apply to strip thicknesses over 0.125 in. (3.2 mm), and for all thicknesses of strip over 12 in. (305 mm) in width.
E. For ductility evaluations for strip under 0.005 in. (0.13 mm) in thickness, the spring-back test, such as that described in Test Method F 155, is often used and the
manufacturer should be consulted.
F. 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.
