Spring stainless steel wire is a type of steel wire mostly used as a raw material for manufacturing various springs.
If the diameter of stainless steel wires is between 0.2-0.8mm, quenching and tempering are then carried out.
Spring stainless steel wires are passed through cold rolling, cold drawing, or heat treating to attain yield strength and elastic properties. These properties are essential for spring wires.
Selecting the best quality material is one of the most important considerations for designing excellent springs. Stainless steel wire is a perfect material for making high-quality springs. Stainless steel wires are very popular for springs due to their excellent corrosion resistance and outstanding yield strength.
Stainless steel wires are available in several types and grades. The grade of stainless steel wire selection depends upon the temperature, load, and environment where the spring will be used.
The spring stainless steel wire is a product of stainless steel alloy. Stainless steel wires have a specific palace in the wire industry.
Stainless steel wire is used for many types of spring-like high-temperature springs, tension springs, high-strength springs, high-pressure springs, and torsional springs.
The composition of stainless steel wire includes nickel carbon, manganese, chromium, sulfur, phosphorus, molybdenum, and silicon.
Spring Stainless steel wires have excellent corrosion and oxidation resistance. Springs are made of stainless steel wires known for their outstanding physical and mechanical properties due to the high and low-temperature resistance spring stainless steel wires used in extreme environmental conditions.
Spring stainless steel wires can be categorized into two types by their surface finish dull surface and shiny bright surface.
In fact, due to the processing variety, the stainless steel spring wire with a dull surface has a slightly higher tensile strength than the wire with a shiny surface, so the dull surface wires are mainly used where there are higher requirements for wire strength, but less for the appearance of the wire.
Grades of Spring Stainless Steel Wire
The spring stainless steel wires are made by three most commonly used series of grades stainless steel 200, stainless steel 300, and stainless steel 400.
Each grade of spring stainless steel wire has its physical and chemical properties.
The 302, 304, and 316L are the three austenitic stainless steel grades mostly used to manufacture spring stainless steel wires. After the heat treatment of these grades, perform a cold drawing process to achieve their high strength.
The grade 302 spring stainless steel wires have 17-19% chromium and 8-10% nickel. The 302 stainless steel has good corrosion resistance and strength. This grade is commonly used in wire industries.
The grade 304 spring stainless steel wires have 18-20% chromium and 8-12 nickel% contents in their composition. This grade is softer than 302 and easy to fabricate.
The 316L grade stainless steel wires have 16-18% chromium and 10-14% nickel, and some small amount of molybdenum. Due to some more content on nickel, this grade of stainless steel has outstanding corrosion resistance properties better than 302 and 304 grades.
Stainless steel wire springs made with alloy are mostly used in more corrosive environments.
Properties of Spring Stainless Steel Wire
Spring stainless steel wire is known for its yield strength and toughness.
Stainless steel wires can be easily formed and shaped after heat treatment.
Due to these specific properties, stainless steel wire is mostly used in spring manufacturing industries.
The addition of 16-20% chromium in the spring stainless steel wire composition can maintain its excellent corrosion resistance properties in extreme environments.
Spring stainless steel wires have excellent elasticity, high yield strength, ductility, good corrosion resistance, and a strength-to-weight ratio at high temperatures up to 343 degrees C. The durability of stainless steel wire can increase the life of a spring under extreme conditions.
Stainless steel spring wires can be used for general and specific purposes, which are relatively inexpensive. Attractive appearance, recyclability, and low maintenance are the properties of stainless steel spring wire that make it unique among good quality wires. Due to these desirable properties, spring stainless steel wires are widely used in many applications.
Spring Stainless Steel Wires Applications
Spring stainless steel wire is a special stainless steel product perfectly designed for excellent corrosion resistance. Stainless steel wires are used in industries and medical applications.
There are many grades and sizes of stainless steel wires, mostly used in manufacturing stainless steel springs. We can make stainless steel wires according to your application needs.
When we make a spring with stainless steel wire, it can resist stress, and after removing the stress, it comes back to its original position without deformation.
Spring stainless steel wire is commonly used in mechanical engineering, electronics equipment, petrochemical and chemical industries, food, paper, pulp, textile, and electrical industries. High-quality springs made with stainless wires are mostly used in the oil, aerospace, chlorination, and fertilizer industries.
Spring stainless steel wires play a vital role in the agriculture and food processing industries. The springs are used in harvesting equipment, and fertilizer processing units made with stainless steel wires.
Grade 300 stainless steel wires are mostly used in marine equipment due to their outstanding corrosion resistance. Stainless steel wire springs are also used in the mining industry due to their toughness and durability against vibration and crushing force.
Why 301 Grade Spring Stainless Steel Wire Is More Popular?
The stainless steel grade 301 belongs to the austenitic stainless steel family.
Grade 301 is very popular in the stainless steel wire industry due to its excellent corrosion resistance, strength, and outstanding ductility.
The cold working increases 301 grade strength and ductility.
Both alloys have the same corrosion resistance when stainless steel grade 301 compared with 304, but 304 grade is more expensive than 301 due to more chromium and nickel contents.
Conclusion
Stainless steel wires are the perfect material for making high quality springs.
Spring stainless steel wires play a significant role in the industry as well as in familiar places. Almost every machine and automotive industry need stainless steel springs.
