Carbon Steel Cold Drawn Annealed Wire(DIN1652 Grade)
Cold drawn steel annealed wire is a type of steel wire that has been cold drawn (drawn through a die at room temperature) and then annealed (heated and cooled slowly) to improve its properties.
Specifications
- Material: Typically made from low-carbon steel, such as SAE 1008 or SAE 1010.
- Diameter: Available in a wide range of diameters, from fine gauge to heavy-gauge wire.
- Tensile strength: Varies depending on the specific grade of steel and the drawing process.
- Ductility: High ductility allows for easy bending and shaping.
- Finish: Can be left bright or annealed for a darker finish.
- Stronger: Cold drawing increases the tensile strength of the wire.
- More ductile: Annealing improves the wire's ability to be bent and shaped without breaking.
- More uniform: Cold drawing and annealing create a more consistent and uniform wire.
Carbon Steel Cold Drawn Annealed DIN1652 Grade is a high-performance wire known for its exceptional tensile strength and flexibility. It undergoes a cold-drawing process followed by annealing, resulting in a wire that is both durable and highly ductile. This combination of strength and softness makes it ideal for a wide range of binding and tying applications across various industries.
DIN 1652 primarily covers cold-drawn steel bars, for binding wire, an annealed wire produced according to DIN 1652 standards would typically be made from low-carbon steel, which has been annealed to improve its ductility and softness, making it easier to work with for binding purposes.
Standards for Cold Drawn Steel Annealed Wire
Cold drawn steel annealed wire is often subject to various standards to ensure its quality and consistency.
- ASTM A227: This ASTM standard covers cold-drawn steel wire for general use. It specifies dimensions, tolerances, mechanical properties, and testing methods.
- EN 10204: This European standard covers the delivery inspection of steel products, including cold-drawn steel wire. It specifies the required documents and testing methods.
- DIN 1652: This German standard covers cold-drawn steel wire for general purposes.
- JIS G3565: This Japanese standard covers cold-drawn carbon steel wire.
- GB/T 3275: This Chinese standard covers cold-drawn steel wire for general use.
Features of DIN 1652 Annealed Wire for Binding:
Material: Low-carbon steel, often in grades like C15 (1.0401) or similar, depending on the specific requirements.
Tensile Strength: Lower tensile strength due to the annealing process, usually around 350–550 MPa, depending on the exact grade and wire diameter.
Diameter: Common sizes for binding wire range from 0.8 mm to 5.0 mm, depending on the application.
Surface Finish: Often available in black (uncoated) or galvanized finishes, depending on the corrosion resistance needed.
Form: Supplied in coils or spools, typically in weights of 1 kg to 25 kg, depending on the manufacturer and application.
Applications: Primarily used for binding in construction, bundling materials, tying in gardening, and similar applications where flexibility and ease of use are important.
Manufacturing Process
- The wire is produced through a meticulous process of cold drawing, which involves pulling the wire through a series of dies to achieve the desired diameter. This is followed by annealing, a heat treatment process that enhances the wire's ductility and softness. The result is a uniform surface finish and consistent diameter, ensuring reliable performance in demanding industrial settings.
Wire Sizes by Diameter
- 0.8mm (0.031 inches)
- 1mm to 2mm (0.039 to 0.079 inches)
- 2.5mm to 4mm (0.098 to 0.157 inches)
- 5mm to 6mm (0.197 to 0.236 inches)
Packaging
- The wire is supplied in coils or spools, with weights ranging from 25 to 1000 kg (55 to 2205 lbs). This flexible packaging ensures that the wire can be easily transported and handled, whether in small-scale projects or large industrial operations.
Features
- High Tensile Strength: The wire is designed to withstand heavy loads and tension, making it suitable for demanding applications.
- Flexibility: Its enhanced ductility allows it to be easily bent and shaped to meet specific requirements.
Excellent Elongation Properties: The wire can stretch without breaking, providing reliability in binding applications.
- Corrosion Resistance: The wire is durable and resistant to corrosion, ensuring longevity in various environments.
Applications
