B Zirconium may be replaced by cerium. When cerium is added, the cerium/sulfur ratio should be approximately 1.5 to 1, based upon heat analysis.
TABLE 2 Tensile and Hardness Requirements
NOTE 1-0n plates wider than 24 in. (610 mm), the test specimen shall be taken in the transverse direction.
NOTE 2-Either the full thickness rectangular specimen shown in Fig. 4 of ASTM Methods and Definitions A 370 for
Mechanical Testing of Steel Products;’ or the ‘h-in. (12.S-mm) diameter specimen shown in Fig. S of Methods A 370 may
be used for plates over ‘/. to 1’12 in. (19 to 40 mm) in thickness.

A Measured at 0.2 % offset or O.S % extension under load as described in Section 13 of Methods A 370.
B Elongation and reduction of area not required to be determined for floor plates.
C For plates tested in the transverse direction, the elongation minimum percent is reduced by 2 % and the reduction of
area minimum requirement is reduced by S %.
D See Section 7.
E When measured on the Fig. 4 (Methods A 370) l’h-in. (40-mm) wide specimen (see Note 2 above), the elongation is
determined in a 2-in. or SO-mm gage length which includes the fracture and shows the greatest elongation.
F When measured on the Fig. S (Methods A 370) liz-in. (12.5-mm) round specimen (see Note 2 above
