Elements not specified in this table should not be intentionally added except for the purpose of finishing the molten steel.
Note a) Do not intentionally add.
b) Mo of SNCM630 may have a lower limit of 0.30%, depending on the agreement between the receiving parties.
c) The Al of SACM645 is 0.70% to 1.20%.

3. Dimensions tolerance

Table 8-Dimensions tolerance of hot rolled wire

直径	直径公差	不圆度
<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

The tolerance of the dimensions of the wire with a diameter of more than 50 mm depends on the agreement between the receiving parties.
Note a) The deviation refers to the difference between the maximum value and the minimum value of the diameter in the same cross-section of the wire.
