7.2 The typical mechanical properties for CS P
(Types A, B, and C), FS (Types A and B),
DDS (Types A and C), and EDDS sheet
designations are listed in Table 5. These
mechanical property values are
nonmandatory. They are intended solely to
provide the
purchaser with as much information as
possible to make an informed decision on the
steel to be specified. Values outside of these
ranges are to be expected.
7.3 When base metal mechanical properties are P
required, all tests shall be conducted in
accordance with the methods specified
in Specification A 924/A 924M.
7.4 Bending Properties Minimum Cold Bending P
Radii—Structural steel and high-strength low-
alloy steel are commonly
fabricated by cold bending. There are many
interrelated factors that affect the ability of a
steel to cold form over a given radius
under shop conditions. These factors include
thickness, strength level, degree of restraint,
relationship to rolling direction,
chemistry, and base metal microstructure.
The table in Appendix X1 lists the suggested
minimum inside radius for 90° cold bending
for structural steel and high-strength low-alloy
steel. They presuppose “hard way” bending

8.1.1 Coating weight [mass] shall conform to the P
requirements as shown in Table 1 for the
specific coating designation. for the
specific coating designation, or
8.1.2 If required, the coating mass shall conform P
to the requirements as shown in Table S2.1
for the specific single spot/single
side coating mass designation (single
spot/single side designations are available
only in SI units).
8.1.3 Use the following relationships to estimate P
the coating thickness from the coating weight
[mass]:
8.1.3.1 1 oz/ft2 coating weight = 1.7 mils coating 1.7 mils P
thickness, and
8.1.3.2 7.14 g/m2 coating mass = 1 μm coating thickness. P
8.1.4 Use the following relationship to convert
coating weight to coating mass:
8.1.4.1 1 oz/ft2 coating weight = 305.15 g/m 2 coating 305.15 g/m P
mass.
8.2 Coating Weight [Mass] Tests : P

8.3.1 The bend test specimens of coated sheet P
designated by prefix “G” [“Z”] shall be
capable of being bent through 180° in
any direction without flaking of the coating on
the outside of the bend only. The coating
bend test inside diameter shall have a
relation to the thickness of the specimen as
shown in Table 6. Flaking of the coating
within 0.25 in. [6 mm] of the edge of the bend
specimen shall not be cause for rejection.
8.3.2 Because of the characteristics of zinc-iron P
alloy coatings designated by prefix “A” [“ZF”] Method A
as explained in the Discussion
following 3.2.8, coating bend tests are not
applicable.
9.2 Disposition of non-conforming material shall P
be subject to the requirements of 9.213.2 of
Specification A 924/A 924M.
