Why Choose It?
Excellent Cold Drawing Performance
Uniform microstructure ensures seamless cold forming, minimizing cracks during wire drawing or fastener production.
Superior Tensile Strength
With a carbon content of 0.60–0.65%, SWRH62A delivers tensile strength up to 1,080–1,230 MPa, ideal for high-stress applications.
Enhanced Durability
Optimized alloying elements (e.g., manganese, silicon) improve wear resistance and fatigue life, reducing long-term maintenance costs.
Consistent Surface Quality
Scale-free surfaces and minimal decarburization enhance coating adhesion and corrosion resistance.
Customizable Specifications
Available in coils or straight lengths, tailored to meet client-specific tolerances and packaging requirements.
Quality Standards
Our SWRH62A high carbon steel wire adhere to globally recognized specifications:
| Standard | Grade Equivalent | Key Compliance |
|---|---|---|
| JIS G3502 | SWRH62A | Chemical composition, tensile test |
| ASTM A510M | Class B | Dimensional tolerances |
| EN 10016-2 | C67D | Cold heading suitability |
Production process
Heating: Place the billet in a step-beam heating furnace and heat it to above 1100 degrees Celsius.
Descaling: The heated billet is taken out of the furnace and descaled by high-pressure water.
Rough rolling: The billet is sent to the rough rolling mill for rolling, which is a hot rolling mill.
Cooling: The rolled piece after rough rolling enters the water cooling section for cooling to control its internal metallographic structure.
Finishing rolling: After leaving the water cooling section, it enters the intermediate rolling mill and the finishing mill for further rolling.
Wire laying: The rolled piece after finishing rolling is spit out by the wire laying machine to form a coil.
Cooling and coiling: The coiled wire is cooled and moved forward in the air cooling section, and is rolled into a coil by the coiler at the end of the air cooling section.
Packing: The rolled steel wire rod is sent to the baler for bundling.
Finished product warehouse: The packaged wires are sent to the finished product warehouse.
