Alloy multi turn wave springs are 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 a high elastic limit, high yield ratio, high fatigue strength, and sufficient toughness.
Alloy multi turn wave springs have the advantages of small size, lightweight, 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 use 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 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 a high elastic limit, good hardenability, and corrosion resistance. The roles of various alloying elements in spring materials are as follows:
Углерод (C) является важным химическим элементом в стали. /(С) пружинной стали колеблется от 0,31ТР3Т до 1,21ТР3Т, из которых /(С) углеродистой пружинной стали составляет от 0,601ТР3Т до 0,901ТР3Т. /(C) находится между 0,46% и 0,75%. Чем выше содержание углерода, тем выше твердость и прочность стали, но снижается пластичность и повышается хрупкость.
Марганец (Mn) обычно добавляют в количестве около 1% в пружинную сталь. Его преимуществами являются хорошая прокаливаемость, высокая прочность и низкая склонность к обезуглероживанию. Недостатком является то, что он имеет чувствительность к перегреву и склонность к отпускной хрупкости, а также велика склонность к растрескиванию во время закалки.
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.
Хром (Cr) может улучшить прокаливаемость и измельчить зерна. Это важный элемент легированной стали, используемой при производстве пружин с высокими усталостными характеристиками. В качестве основного аддитивного элемента используется нержавеющая сталь. Однако хром может вызывать отпускную хрупкость, и его необходимо быстро охлаждать после отпуска, чтобы избежать возникновения отпускной хрупкости.
Nickel (Ni) is an element with fewer 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 a stable austenite structure. The structure of chromium-nickel austenite is stable, and it will not become embrittled after long-term use at high temperatures.
