Annealed carbon steel wire is a carbon steel wire that has been annealed. It has good flexibility and machinability and is widely used in various industrial and construction applications.
Annealed carbon steel wire is mainly made of carbon steel. Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to the carbon content. Annealed carbon steel wire is usually made of low carbon steel (carbon content less than 0.25%) or medium carbon steel (carbon content between 0.25%-0.60%).
The production process of annealed carbon steel wire mainly includes the following steps:
Wire drawing: The steel billet or steel coil is drawn into a steel wire of the required diameter through a wire drawing machine.
Annealing: The drawn steel wire is heated to a certain temperature (usually 700-900°C) and then slowly cooled to eliminate the stress inside the steel wire and improve its flexibility and ductility.
Pickling: The oxide scale and impurities on the surface of the steel wire are removed by pickling to ensure the smooth surface of the steel wire.
Lubrication: Lubricant is applied to the surface of the steel wire for subsequent processing.
According to different uses and performance requirements, annealed carbon steel wire can be divided into the following categories:
Ordinary annealed steel wire: used for general industrial purposes, such as bundling, fixing, etc.
High-strength annealed steel wire: has higher strength and hardness, suitable for applications requiring higher mechanical properties.
Special annealed steel wire: has special properties, such as corrosion resistance, high temperature resistance, etc., suitable for use in specific environments and conditions.
The steel grade of annealed carbon steel wire is usually determined according to the chemical composition and mechanical properties of the steel. Common steel grades include:
Q195, Q235: low carbon steel, commonly used for ordinary annealed steel wire.
45#, 60#: medium carbon steel, commonly used for high-strength annealed steel wire.
65Mn: carbon steel with a high manganese content, with high strength and high toughness.
The production and quality of annealed carbon steel wire usually need to comply with the corresponding national and international standards, such as:
Chinese standard: GB/T 343-1998 (carbon steel wire)
American standard: ASTM A853 (standard carbon steel wire)
European standard: EN 10270-1 (standard for steel wire)
Annealed carbon steel wire has a wide range of uses, mainly including:
Construction and decoration: such as tying steel bars, building formwork, wire mesh, etc.
Industry and agriculture: such as bundling items, making nails, ropes, baskets, etc.
Manufacturing: such as making various springs, mechanical parts, electrical accessories, etc.
Daily life: such as hangers, clips, handicrafts, etc.
Annealed carbon steel wire has a wide range of uses in various fields due to its good flexibility and processability, and is a very important basic material.
