Carbon steel wire is a versatile metal wire made of iron and carbon. Its strength and ductility vary with carbon content, and it is widely used in construction (nails, wire mesh, reinforcing bars), automotive parts, springs, fasteners, and tools. Its properties and applications differ depending on the specific carbon content, which categorizes it into low-carbon steel, medium-carbon steel, and high-carbon steel. Carbon steel wire has various surface treatments, such as galvanizing or annealing. It is known for its high tensile strength, but it is prone to rusting without coating.

Q195 Carbon Steel Wire is a widely used, cost-effective low-carbon steel known for excellent ductility, plasticity, and weldability, making it ideal for drawing into wires for nails, fencing, binding wire, and structural components, though it offers lower strength compared to higher-grade steels, with typical uses in construction, automotive, and furniture. It features low carbon content (around 0.06-0.12%), good formability, and is often processed into galvanized wire for improved corrosion resistance.

Q235 Carbon Steel Wire is a versatile, low-cost steel wire from China (GB/T 700 standard), known for its strength, ductility, and ease of processing, commonly made into wire rods for construction (nails, mesh), machinery (springs, cables), and general manufacturing, often processed via cold drawing and sometimes galvanized for rust resistance, with ASTM A36 being a U.S. equivalent.

Q275 Carbon Steel Wire is a versatile, general-purpose structural steel known for good strength, weldability, and formability, often used in construction, machinery, and spring manufacturing, equivalent to European S275 grades and commonly found as wire rod or coils for various industrial applications.

Q345 Carbon Steel Wire is a high-strength, low-alloy steel wire known for its 345 MPa yield strength and 470-630 MPa tensile strength, making it excellent for construction, binding, and structural uses, comparable to ASTM A572 Grade 50 or S355JR, offering good toughness and load-bearing capacity for demanding applications.

82B High Carbon Steel Wire is a specific grade of strong, resilient wire (often SWRH 82B) with around 0.8% carbon, known for its high tensile strength, hardness, and elasticity, making it ideal for industrial springs, nails, ropes, fencing, and even musical instruments. It's produced by drawing wire rod and offers excellent performance in applications requiring bending, compression, or extension, returning to its original shape.

65Mn Spring Steel Wire is a strong, high-carbon manganese alloy steel known for excellent elasticity, hardness, and wear resistance, making it ideal for small to medium springs in general machinery, tools, and DIY projects, offering good performance and durability after heat treatment, though it has poor hardenability for larger parts. It's a common Chinese standard (similar to AISI 1065) used when high strength and flexibility are needed without the cost of alloy steels.

SAE 1010 carbon steel wire is a low-carbon, economical steel known for good ductility, formability, and weldability, making it ideal for deep drawing, fasteners (screws, rivets, nuts), automotive parts (fenders, pans), and general engineering, often used as wire rod for further processing into mesh, nails, or galvanized wire, characterized by its low carbon content (around 0.10%).

SAE 1006 carbon steel wire is a versatile, low-carbon, non-alloy steel known for its high ductility, excellent cold formability, and good weldability, making it ideal for drawing into wire for nails, mesh, fasteners (bolts, screws, nuts), and general engineering parts where light stress and easy shaping are needed. It's primarily composed of iron with low carbon (max 0.08%), manganese, sulfur, and phosphorus, and is often supplied as wire rod for further processing.

Classification: Low-carbon steel.
Carbon Content: Typically ranges from 0.08% to 0.12%.
Key Properties: High ductility, excellent formability (ideal for cold working processes), and good weldability without special precautions.
Mechanical Strength: Offers adequate strength for non-critical structural applications, with a typical tensile strength of approximately 400-550 MPa.
Corrosion Resistance: The material is not inherently corrosion-resistant and generally needs to be coated or painted to prevent rust.
Processing: Can be processed through bending, welding, punching, decoiling, and cutting.

SAE 1035 carbon steel wire is a medium-carbon steel known for good strength, wear resistance, and formability, often used for fasteners, bolts (like Class 8.8), and industrial hooks; it's processed as cold-drawn wire (CHQ) with black phosphate coating, offering a balance between ductility and hardness, making it excellent for cold forging.

SAE 1045 Carbon Steel Wire is a strong, medium-carbon steel known for its good balance of hardness, strength, and machinability, making it excellent for applications like fasteners (bolts, studs, screws), shafts, gears, and machine parts, often available as wire rod or cold-drawn wire for various industrial uses requiring durability and good wear resistance.
