In this paper, the development of stainless steel wire technology will be discussed, including the application of stainless steel wire in various industries and the various types, materials and technologies of high-strength stainless steel wire available. Finally, the paper concludes with a discussion of the development trend of this technology.

Introduction

High-tensile-resistant steel wire is the general term for steel wire products made of high-strength alloy steel or high-strength carbon steel and special steel. Stainless steel wire can be used in industries such as footwear, textiles, construction and infrastructure engineering, production of metal mesh, metal cords and filtration products. Steel wire products produced with high tensile-resistant steel wires have high tensile strength, high elasticity, low weight and good flexibility.

High-tensile-resistant steel wires are divided into four main categories according to the different grades of steel wire tensile strength. These four categories are high-strength carbon steel wire, high-strength alloy steel wire, high-strength stainless steel wire and special high-strength steel wire. High tensile strength of steel wires, such as carbon steel, can be improved by adding alloying elements such as chromium, manganese, phosphorus and molybdenum. Stainless steel wire is generally made of steel containing more than 10.5% chromium, which makes it more resistant to corrosion and oxidation. Special high-strength steel wires include titanium, nickel and cobalt alloy wires, which are widely used in aerospace, military, and medical fields due to their increased strength and static properties.

Application of High-tensile-resistant Steel Wire

High-tensile-resistant steel wires have many advantages which make them suitable for a variety of industrial applications. They are superior to ordinary wires in terms of tensile strength, elasticity and fatigue performance, which makes them suitable for threading, weaving and machinery, and for connecting other components. Their low weight, good plasticity, and high resistance to tension, compression, wear and corrosion make them suitable for applications such as fishing nets, filter nets and fasteners. High-tensile steel wire is also used in facilities such as bridges, towers, oil and gas pipelines and overhead lines.

High-tensile-resistant Steel Wire Materials

As mentioned above, high-tensile-resistant steel wire is divided into four categories according to their tensile strength: carbon steel, alloy steel, stainless steel, and special high-strength steel. Generally, high-tensile steel wire is made of low-cost carbon or low-alloy steel, which is then alloyed to improve its tensile strength and elasticity. The most common alloying elements used are chromium, manganese, phosphorus and molybdenum. Other more expensive alloying elements may be used to produce special high-strength steel wires such as titanium, nickel and cobalt alloys.

High-tensile-resistant Steel Wire Technology

There are several different methods of manufacturing high-tensile-resistant steel wire, most of which involve a combination of heat treatment, hardening and other processes. The most common methods are cold-drawing, hot-drawing and hot-rolling. Depending on the desired properties of the wire and the raw material used, the cold-drawing process often involves few steps and is used to produce wires with high tensile strength and uniformity. The hot-drawing process is often used when a high degree of fine-grained structure is required, as this method can produce wires that are stronger and more elastic. Hot-rolling is used for larger cross-section wires and produces wires with high strength and ductility.

Development Trend of High-tensile-resistant Steel Wire Technology

The use of high-tensile-resistant steel wire will continue to grow as industrial applications become increasingly complex. To meet the growing demand for high-quality steel wire, manufacturers are constantly working to develop new materials and technologies. In the near future, stainless steel wire containing high-strength alloy elements and special high-strength steel wires will become increasingly common, as they are resistant to corrosion and oxidation and can be used in a wide range of applications. In addition, new surface treatment technologies are also being developed, such as the application of nano coatings and the use of high-frequency wave treatments, to improve the surface properties of steel wires and to make them more resistant to corrosion and wear.

Conclusion

High-tensile-resistant steel wire has a wide range of applications in various industries. Through the use of different steel wire materials and processes, manufacturers are able to produce wires with high strength and ductility, corrosion resistance and wear resistance. In the future, new materials and technologies will be developed to improve the performance of steel wires and to meet the demands of different industrial applications.

High strength steel wire rope is widely used in many areas, such as hoisting, construction, transportation, marine, petroleum exploitation, etc. And the high tensile strength plays an important role in achieving the purpose of heavy loads. The technical level of high tensile strength steel wire rope has been greatly improved in the past few years.

At first, high strength steel wire rope were made of the same diameter strands. Its break loading was greatly low than current one, just can used in some light loading. In the later phase, the main materials had largely changed to the high strength low alloy steels. These steels have higher strength、toughness、fatigue resistance and stress corrosion resistance properties. But these properties can’t well meet the high strength steel wire rope requirement. Later, the original high strength low alloy steels has been gradually replaced by spring steels( such as silicone-manganese steel), stainless steel and special steel, etc. With this replacement, the break loading of the high strength steel wire rope had greatly improved, which is look like 5 times more than the original one.

At the same time, the technology of multi-stranded wire ropes has been developed. We use more strands in according to these wire rope structure，which being able to provide higher break loading while remaining the same diameter. Then the construction of the high strength steel wire rope can provide corresponding performance when dealing with the heavy loaded object.

In addition, the rope core also needed to be improved to have enough flexibility and wear resistance when using. This can make the wire rope have enough usage life in terms of its extending ratio. And the lubrication and plastic material have great significant too. Wire rope lubrication can reduce the friction loss, and plastic materials can prevent the wire rope getting abraded.

Overall, high strength steel wire rope technology has been improved greatly in the past few years. And the future development will still require more attention and focus on furthering increasing the break loading of steel wire rope and improving energy saving, operation flexibility and environmental protection.
