Ungalvanized High Carbon Patented Steel Wire
The non galvanized high carbon patented steel wire is subjected to lead quenching (Patented) heat treatment process, and the high carbon steel (with a carbon content of 0.45% -1.0%) is formed into a uniform martensite structure through precise temperature control, and then strengthened by cold drawing.
Features
product presentation
The non galvanized high carbon patented steel wire is subjected to lead quenching (Patented) heat treatment process, and the high carbon steel (with a carbon content of 0.45% -1.0%) is formed into a uniform martensite structure through precise temperature control, and then strengthened by cold drawing. The product combines ultra-high strength (>2000 MPa) and excellent ductility, with a surface that retains the original metallic luster and no interference from galvanized layers. It is suitable for precision spring and cable manufacturing that requires subsequent coating or direct contact conditions
Core advantages
Patented technology endows ultra-high performance
The content of martensite is ≥ 90%, the tensile strength reaches 1800-2200 MPa, and the elastic limit is increased by 30%;
Twisting performance ≥ 15 times (D=wire diameter), fatigue life exceeding one million cycles.
Significant advantages of non galvanized surface
Avoiding the risk of hydrogen embrittlement in coatings and improving material reliability;
Bare surface reinforcement and adhesive strength with rubber/plastic, suitable for composite cable cores and sealing13;
Environmentally friendly and low-carbon, omitting the electroplating process and reducing wastewater discharge.
Precision dimensions and consistency
Diameter range: Φ 0.50mm - Φ 12.0mm (supports customization of ultra-fine wire with a diameter of Φ 0.10mm), with a tolerance control of ± 0.02mm2;
Surface smoothness Ra ≤ 0.2 μ m, reducing spring forming wear.
Application area
Heavy machinery
Crane cables, excavator rigging with high tensile strength (2160 MPa grade) to resist impact loads
Automotive suspension
Clutch springs, shock absorber coil springs, and Paden off technology enhance anti relaxation and extend lifespan
Energy drilling
Oil drilling rig lifting cables, well control equipment springs without galvanized layer to avoid underground corrosion failure
Precision instruments
Sensor elastic components, customized ultra-fine wire springs for medical equipment (Φ 0.10mm+), suitable for miniaturization design
