この表に規定のない元素は，受渡当事者間の協定がない限り，溶鋼を仕上げる目的以外に意図的に添加してはならない。注a）線材のCuは，0.20 %以下とする。

The elements not specified in this table should not be intentionally added except for the purpose of finishing the molten steel, unless there is an agreement between the receiving parties.
Note a) The Cu of the wire is 0.20% or less.

2. Mechanical properties of the line

A value of a mechanical nature may be agreed between the receiving parties.

3. Dimensions tolerance

Table 4-Dimensions tolerance (wire)

径	径の許容差	偏径差
<15	±0.30	<0.40
15<d≤25	±0.40	<0.50
25<d≤35	±0.40	<0.50
35<d≤40	±0.40	<0.50

The tolerance for dimensions with a diameter of more than 40 mm depends on the agreement between the receiving parties.

4. Tolerance limit of total coal-decalting depth

Table 9-Tolerant Limits of total coal-decalination depth (Cold drawn steel)

冷間引抜丸鋼		冷間引抜線
径	表面からの全脱炭層深さ	径	表面からの全脱炭層深さ
<15	<0.20	≤7	<0.05
15<d≤25	<0.25	7<d≤15	<0.08
25<d≤35	<0.30	15<d≤20	<0.10

The allowable limits for the dimensions of the cold drawn round steel with a diameter of more than 35 mm and the diameter of the cold drawn line with a diameter of more than 20 mm are in accordance with the agreement between the receiving parties.

5. Hardness

Table 10-Spherical Scinding Hardness (Rolled Steel for Cutting)

種類の記号	硬さ
種類の記号	HBW	HRB	HV
SUJ2,SUJ4	<201	<94	<218
SUJ3,SUJ5	<207	<95	<223

The heat-rolled steel for cutting that has been subjected to spherical sintered was tested at 14.3, and its hardness was determined by either Brinell hardness (HBW), Rockwell hardness (HRBW) or Vickers hardness (HV) in Table 10. However, the Vickers hardness (HV) may be applied only when the diameter is 17 mm or less. In addition, the hardness of the cold drawn steel and the low-temperature burnt hardness of the forged steel are in accordance with the agreement between the receiving parties.
