There is provided a high-carbon steel wire rod and a preparation method thereof. Wherein, the high-carbon
steel wire rod comprising the following ingredients: C, Si, Mn, Cr, V, Ti and Fe. The high-carbon steel wire rod
has satisfactory mechanical properties, including high strength with an average tensile strength of 1560MPa as
well as good plasticity with an average after-fracture shrinkage rate of 30% and an after-fracture elongation
percentage larger than or equal to 9%, which can meet the performance requirements for producing 2300MPa
level pre-stressed steel strand.

Construction Industry
High Carbon Steel Coils are widely used in industrial purposes, such as :
(A) Prestressed Concrete Steel Wire (PC Steel Wire) for reinforced concrete structures
(B) PC strand wire for large, high-quality construction
(C) Wire rope for cable use
Springs
High Carbon Steel wire rod are also used in springs, such as :
(A) Hard-drawn Steel Wire & Oil Tempered Steel Wire for mechanical springs
(B) Oil Tempered Piano Wire for Valve spring & Oil Tempered Piano Wire
Automobile Industry
To use in reinforced tires,wire rod need to be drawn as wire which has small diameter between 0.15mm – 0.38mm
and has the property of high tension & high intensity to face any non – destructive production process.

High Carbon Steel Wire Rods

High Carbon Steel Wire Rods

Scope
1.1 This standard covers high carbon steel wire rods to be used for the
manufacture of hard drawn steel wires, oil-tempered steel wires, hard
drawn steel wires for pre-stressed concrete, galvanized steel wire
strands, wire ropes, etc.
1.2 This standard does not cover wire rods for making piano wires.
Definition
For the purposes of this standard, the following definitions apply:
2.1 HIGH CARBON STEEL WIRE RODS, hereinafter referred to as “wire
rods,” means semi-finished hot rolled carbon steel products with a
circular cross-section in the form of coiled wire, with a chemical
composition and symbols as specified in Table 1 or Table 2.
2.2 COIL means a wire rod of continuous length without joints, wound into a
coil.
2.3 RUST means an ionic compound on a metal surface generated by the
reaction of iron (Fe) and oxygen (O2), catalysed by moisture.
2.4 PITTING means rust eroding the metal surface into deep holes,
generated by the reaction of iron and oxygen, catalysed by moisture and
solutions with a chloride compound as a catalyser (solutions with a
chloride compound like sea water).
