Multi Turn Wave Springs A286 Alloy

Product Description

MultiWave wavy Springs Compression Springs with plain ends manufacturers


  1. Alloy multi turn wave springs are made of a single filament of round-edged, pre-tempered flat wire from a continuous coil.
  2. This results in uniform diameters and wave heights. They replace conventional round wire springs when space is critical, typically occupying only 1/3 to ? of the compressed height space, while providing more deflection with the same load specifications.
  3. Alloy multi turn wave springs should be used for all applications requiring tight load deflection specifications where axial space is critical.


Alloy multi turn wave springs is a material with metal specificity, which is formed by the fusion of a metal element with other metal or non-metal elements. Generally, the melting point of the alloy is lower than that of the metals that make it up, and the hardness is higher than that of the metals that make it up.

Alloy multi turn wave springs steel performance characteristics Manufacture of various elastic components such as constant coil springs, leaf springs, etc. It is required to have high elastic limit, high yield ratio, high fatigue strength and sufficient toughness.

Alloy multi turn wave springs have the advantages of small size, light weight, good corrosion resistance and fatigue resistance. Since the shear modulus of the alloy material is greater than that of the high carbon spring, the number of turns required to bend is smaller than the number of turns of the spring. Even though both materials have the same specific gravity, alloy multi turn wave springs are lighter than high carbon springs because it uses less material. In most cases, the weight of alloy multi turn wave springs is 60%~70% lighter than that of high carbon springs, and the height design of alloy multi turn wave springs can also be reduced, which is 50%~80% lower than that of high carbon springs. Another advantage of alloy steel springs is corrosion resistance. Also, unlike steel springs, alloy multi turn wave springs do not require a protective coating.

The role of alloying elements in spring materials

The chemical elements of the spring material are mainly iron and carbon. In order to ensure that the spring can meet the needs of working under different conditions, a certain amount of alloying elements are added on the basis of carbon spring steel, so that the material has the characteristics of carbon spring steel. It does not have excellent properties, such as high elastic limit, good hardenability and corrosion resistance. The roles of various alloying elements in spring materials are as follows:

Carbon (C) is an important chemical element in steel. The /(C) of spring steel ranges from 0.3% to 1.2%, of which the /(C) of carbon spring steel is between 0.60% and 0.90%. /(C) is between 0.46% and 0.75%. The higher the carbon content, the higher the hardness and strength of the steel, but the plasticity decreases and the brittleness increases.

Manganese (Mn) is usually added in an amount of about 1% in spring steel. Its advantages are good hardenability, high strength, and low decarburization tendency. The disadvantage is that it has overheating sensitivity and temper brittleness tendency, and the cracking tendency during quenching is also large.

The content of silicon (Si) in carbon steel is usually not more than 0.37%, and it is added to the steel as a deoxidizer in the smelting process. The silicon-containing alloy spring steel (Si) is between 0.70% and 2.80%. Since silicon can dissolve in ferrite, the ferrite can be significantly strengthened, thereby improving the strength and yield ratio of the steel, and silicon can also improve the hardenability and tempering stability of the steel. However, the silicon content in the spring steel should not be too high, otherwise it will cause the grains of the steel to coarsen and increase the tendency of graphitization.

Chromium (Cr) can improve the hardenability and refine the grains. It is an important element in the alloy steel used in the manufacture of springs with high fatigue performance. The main additive element in the stainless steel used. However, chromium can cause temper brittleness, and it needs to be cooled quickly after tempering to avoid the occurrence of temper brittleness.

Nickel (Ni) is an element with less resources in our country, and it is rarely used in spring steel. It is the main component of austenitic stainless steel. Nickel is mainly used to form stable austenite structure. The structure of chromium-nickel austenite is stable, and it will not become embrittled after long-term use at high temperature. As a professional alloy multi turn wave springs exporter, we have many years of production experience, and our products are widely used in aerospace, precision machinery, hydraulic seals and high-end motors.
