 | | One of the major lines of production which was commissioned in the year 1995 is Steel Wire for Round Cable Armoring. The manufacturing capacity of this wire is 2400 METRIC TONES PER YEAR.
The general properties of this wire are given hereunder: |
| | | Chemical Composition :
|
|
| Carbon | Manganese | Silicon | Sulphur | Phosphorus | | 0.10% Maximum | 0.30-0.50% | 0.10% Maximum | 0.05% Maximum | 0.05% Maximum |
|

Diameters / Size Tolerance :
The diameter of the wire and tolerance is controlled as under :
|
| Nominal Diameter (mm) | Tolerance (mm) | | 0.25 | + 0.02 | | 0.30 | + 0.02 | | 0.45 | + 0.02 | | 0.70 | + 0.04 | | 0.90 | + 0.05 | | 1.25 | + 0.05 | | 1.40 | + 0.06 | | 1.60 | + 0.08 | | 2.00 | + 0.08 | | 2.50 | + 0.10 | | 3.15 | + 0.12 | | 4.00 | + 0.12 |
Joints in Coils: The Welds are not less than 100 meters from either end of the coil. All the
surface irregularities at the weld are removed to give a smooth finish before galvanizing.
Zinc Coating: This is controlled as per requirement of the customer.
Tensile Strength: The tensile strength of the wire is maintained between 300 and 500 Mps.
Elongation of Wire: As per customers' specifications.
Torsion: It is maintained as under :
|
| Nominal Dia of Wire
(mm) | G.L.
(mm) | Minimum No. of Turns | | 0.25 | 50 | 67 | | 0.3 | 50 | 67 | | 0.45 | 75 | 67 | | 0.70 | 75 | 43 | | 0.90 | 75 | 33 | | 1.25 | 75 | 24 | | 1.40 | 150 | 43 | | 1.60 | 150 | 37 | | 2.00 | 150 | 30 | | 2.50 | 150 | 24 | | 3.15 | 150 | 19 | | 4.00 | 150 | 15 |
Electrical Resistance: Resistivity of the wire is corrected to 200C and does not exceed 14.5x10-6 ohm-cm.
Coil Weight: As per customers' specifications.
Packing: As per customers' specifications.
