Steel wire and iron wire have many similarities, but if you distinguish them carefully, you will find that they are not only different in material, but also in product characteristics. So when choosing, be sure to make a clear distinction between the two. The iron wire factory introduces that the steel wire is made of carbon structural steel or above, generally not galvanized, and is used for machinery and springs. Black, very hard; iron wire: made of low carbon steel (mild steel), galvanized, used for connection and binding. White and soft.
The main difference between the two is the carbon content. The carbon content of iron is greater than or equal to 2.11 percent, while the carbon content of steel is less than or equal to 2.11 percent. Iron-carbon alloys with a carbon content of more than 2.11% are cast iron (pig iron), which basically has no ductility and cannot be drawn into wire. Secondly, the content of impurities is different, and the content of harmful impurities such as sulfur and phosphorus in steel is smaller. Generally, the color of the steel wire is focused, and the color of the iron wire is lighter or white.
What is called “iron wire” in life is actually “low carbon steel wire” with a carbon content of less than 0.2%. Because it is prone to rust, the surface is usually galvanized. Under atmospheric conditions, it will not corrode until most of the galvanized layer falls off, and is relatively soft. The so-called “steel wire” in life is “medium carbon steel wire” with a carbon content of about 0.6%, or “high carbon steel wire” with a carbon content of about 0.8%. They have sufficient hardness and strength after proper heat treatment. Elasticity, high strength. In terms of usage, such as winding ordinary springs, etc.
Annealed wire is a kind of soft iron wire made of low carbon steel by cold drawing, heating, constant temperature, heat preservation and other processes. According to different uses, the composition of iron wire is different. It contains: iron, cobalt, nickel, copper, carbon, zinc, and other elements. Roll the hot metal billet into a 6.5mm thick steel rod, that is, a wire rod, and then put it into the wire drawing device to draw wires of different diameters, and gradually reduce the diameter of the wire drawing disc for cooling, annealing, coating and other processing The process is made into iron wires of various specifications.
Annealed wire is mainly soft iron wire made by low-carbon steel heating, hot drawing, constant temperature and other processes. Because of the different uses, the manufacturing process is also different, and the specifications are also various. . The reason why annealed wire can be widely used is that annealed wire has many advantages like other types of iron wire.
Regular maintenance and maintenance saves a lot of time and cost of maintenance and maintenance. It has good stability and good corrosion resistance, which greatly prolongs the service life. There are many types, which can be selected according to different uses. The device for making annealed wire is relatively simple, which improves the utilization rate of the device.
