Carbon Steel Wire

1.Diameter range: 0.2-20mm.

2.Main application:making spring,mattress,wire rope.

3.Standard: GB4357,DIN17223,JIS G 3521.

4.Grade: 60#, 65#, 70#, 72B, 80#, 82B, 65Mn etc.

5. Characteristic: High tensile strength,small tolerance

Shiny surface, good corrosion prevention
6. Packing type:Spool or Coil

7. Application: Being used for stranded conductors in overhead power circuitry
8. Remarks during use and handling:
a. During transportation, handle softly and carefully, avoid bumping and damaging the steel wires. Moisture and rain prohibited. Steel wires must be stored in dry and well ventilated indoors
b. Pay attention to the direction of steel wires when paying-off. Be sure the spool or coil is rotationg freely as to achieve identical tension of all the steel wires

c. In case of batch usage, the remaining should be repacked to avoid oxidizing of the surface
