Remarks 1. The line used for the product to be heat treated, which is SWCH6R to SWCH27K type, can have the lower limit of the tensile strength lower than the value in Table 3 according to the agreement between the receiving parties. 2. When the diameter of the wire is 20 mm or more, the aperture is reduced by 5 from the value of Table 3. For 3 mm or less, the diaphragm is not defined. 3 1N/mm2 = 1MPa

3. Depth of coal-decalination

≤15	≤0.02	≤0.15
>15~25	≤0.03	≤0.20
>25~32	≤0.04	≤0.25

In the case of the line between the decarburying depth SWCH30K and SWCH50K and the designation of the orderer, the test of 10.3.1 is performed, and the allowable limit of the average decarburying depth is in accordance with Table 4. However, for a line having a diameter of more than 32mm, it is according to the agreement between the receiving parties.

4. Allowance of wire diameter and differential deviation

Table 5 Allowance of Wire Diameter and Difference Difference

線径	許容差	偏径差
3以下	0-0.025	0.013以下
3を超え6以下	0-0.030	0.015以下
6を超え 10以下	0-0.036	0.018以下
10を超え 18以下	0-0.043	0.022以下
18を超え 30以下	0-0.070	0.035以下
30を超え 40以下	0-0.100	0.050以下
40を超え 50以下	0-0.150	0.070以下

Note (4) The deviation difference refers to the difference between the maximum value and the minimum value of the diameter in the same cross section of the line.
