0.20≤d≤3.60 | 1470 1570 1670 1770 | |
A类镀锌钢丝 | 3.60<d≤4.40< span=""> | 1370 1470 1570 |
3.00<d≤3.60< span=""> | 1370 1470 1570 1670 | |
0.20≤d≤3.00 | 1370 1470 1570 1670 1770 |
注:公称直径间隔,直径不大于0.40mm的钢丝,其公称直径间隔为0.02mm。直径大于0.40mm到2.00mm的钢丝,其公称直径间隔为0.05mm,直径大于2.00mm的钢丝,其公称直径间隔为0.10mm。在特殊情况下,允许采用中间公称直径的钢丝。
(2)尺寸规格和允许偏差见表7-152。
表7-152制绳用钢丝的实测直径允许偏差 (mm)
钢丝公称直径d | 允许偏差 | |
光面、B类和AB类镀锌钢丝 | A类镀锌钢丝 | |
0.20≤d<0.60 | ±0.01 | ±0.03 |
0.60≤d<1.00 | ±0.02 | ±0.03 |
1.00≤d<1.60 | ±0.02 | ±0.04 |
1.60≤d<2.40 | ±0.03 | 土0.05 |
2.40≤d<3.70 | ±0.03 | 士0.06 |
3.70≤d≤4.40 | ±0.04 | ±0.07 |
注:1.钢丝公称直径应符合表中的规定。
2.钢丝实测直径是指在同一横截面互相垂直的方向上,两次测量所得直径的算术平均值。
3.在钢丝同一横截面上最大直径与最小直径之差为钢丝的圆度。其值不得大于钢丝直径公差之半。
(3)力学和工艺性能见表7-153~表7-155。
表7-153抗拉强度差值
钢丝公称直径d/mm | 抗拉强度差值/MPa | 钢丝公称直径d/mm | 抗拉强度差值/MPa |
0.20≤d<0.50< span=""> | 390 | 1.50≤d<2.00 | 290 |
0.50≤d<1.00 | 350 | 2.00≤d<4.40 | 260 |
1.00≤d<1.50 | 320 |
|
|
注:表7-151中规定的公称抗拉强度是钢丝抗拉强度的下限,上限等于下限加上表中规定的差值。
