1. Chemical composition

Table 3 -- Chemical components (molten steel analysis)

Type	Symbol	化学成分（溶鋼分析）a）
Type	Symbol	C	Si	Mn	P	S	Cr	Mo	V
Type 1	SNB 5	≥0.10	≤1.00	≤1.00	≤0.040	≤0.030	4.00 ~ 6.00	0.40 ~ 0.65	–
Type 2	SNB 7	0.38 ~ 0.48	0.20 ~ 0.35	0.75 ~ 1.00	≤0.040	≤0.040	0.80 ~ 1.10	0.15 ~ 0.25	–
Type 3	SNB16	0.36 ~ 0.44	0.20 ~ 0.35	0.45 ~ 0.70	≤0.040	≤0.040	0.80 ~ 1.15	0.50 ~ 0.65	0.25 ~ 0.35

Note a) The elements not specified in this table shall not be intentionally added to the steel except for the purpose of finishing the molten steel, unless there is an agreement between the receiving parties.
b) When the diameter of the bolt material exceeds 90mm, the upper limit of the carbon content of the SNB7 can be set to 0.50%.

2. Mechanical properties of the wire

Table 4 -- Mechanical Properties

Type	Symbol	Diameter mm	耐力 N/mm2	Tensile strength N/mm2	Elongation after fracture %	Reduction of area %
Type 1	SNB 5	≤100	≥550	≥690	≥16	≥50
Type 2	SNB 7	≤63	≥725	≥860	≥16	≥50
		63<d≤100	≥655	≥800	≥16	≥50
		100<d≤120	≥520	≥690	≥18	≥50
Type 3	SNB16	≤63	≥725	≥860	≥18	≥50
		63<d≤100	≥655	≥760	≥17	≥50
		100<d≤180	≥590	≥690	≥16	≥50

3. Dimensions tolerance

Table 6 -- Dimensions Tolerance of Hot Rolled Wire Lines

Diameter	Diameter tolerance	Out-of-roundness
<15	±0.3	<0.4
15<d≤25	±0.4	<0.5
25<d≤32	±0.5	<0.6
32<d≤50	±0.6	<0.7

If the diameter exceeds 50mm, it is due to the agreement between the receiving parties.
Note) The deviation difference is the difference between the maximum value and the minimum value of the diameter in the same cross section of the wire.
