SWRM6	<0.08	<0.06	<0.040	<0.040
SWRM8	<0.10	<0.06	<0.040	<0.040
SWRM10	0.08-0.13	0.30-0.60	<0.040	<0.040

SWRM17	0.15-0.20	0.30-0.60	<0.040	<0.040
SWRM20	0.18-0.23	0.30-0.60	<0.040	<0.040
SWRM22	0.20-0.25	0.30-0.60	<0.040	<0.040

Elements other than the table should not be intentionally added except for the purpose of finishing the molten steel. However, B may be added depending on the agreement between the receiving parties. In that case, JA.3. a) In the case of the quild steel designation, K is appended to the end of the type symbol. Example SWRM10K b) By agreement between the receiving parties, JA.2.

2. Diameter of wire wire and its tolerance and differential deviation

Table 3-Tolerance and Difference

Diameter	Tolerance	Out-of-roundness a)
≤ 15	±0.40	≤ 0.64
Over 15 up to and including 25	±0.50	≤ 0.80

If the diameter exceeds 25mm, it is due to the agreement between the receiving parties. (a) 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 wire.
