carbon spring steel (i.e. non-alloy spring steel) and other It is cheap but has poor hardenability and is suitable for non-important springs with smaller cross-sections, among which it is the most commonly used. The carbon content (mass fraction) of carbon spring steel is generally .%~.%. According to its manganese content, it is divided into two categories: general manganese content (mass fraction) (.%~.%) such as,
Alloy spring steel
According to the different types of main alloying elements, it can be divided into two categories: - spring steel and spring steel. The former has higher hardenability than carbon steel and is not very expensive, so it is the most widely used and is mainly used for various types of springs with cross-sectional dimensions not larger than 10%. It is a typical representative of the latter. The latter has better hardenability and high comprehensive mechanical properties. The surface of the spring is not easy to decarburize, but the price Relatively high springs are generally used for important springs with larger cross-section sizes. Alloy spring steel is a steel that is based on carbon steel by appropriately adding one or several alloying elements to improve the mechanical properties, hardenability and other properties of the steel to meet the performance requirements for manufacturing various springs. The basic series of alloy spring steel include silicon-manganese spring steel, silicon-chromium spring steel, chromium-manganese spring steel, chromium-vanadium spring steel, tungsten-chromium-vanadium spring steel, etc. On the basis of these series, some grades have alloy elements such as molybdenum, vanadium or boron added in order to improve certain aspects of their performance. - In addition, Xiangyun also selects some grades from other steel types such as high-quality carbon structural steel, carbon tool steel, high-speed tool steel, and stainless steel as spring steel. Spring steel refers to steel specifically used for the manufacture of springs and elastic elements due to its elasticity in the quenched and tempered state. The elasticity of steel depends on its ability to elastically deform, that is, its ability to elastically deform within a specified range so that it can withstand a certain load without permanent deformation after the load is removed. Spring steel should have excellent comprehensive properties such as mechanical properties. (especially elastic limit, strength limit, yield-strength ratio), anti-elasticity loss performance (i.e. anti-elasticity loss performance, also known as anti-relaxation performance), fatigue performance, hardenability, physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance , corrosion resistance, etc.).
In order to meet the above performance requirements, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), precise shape and size.
Springs are used under impact, vibration or long-term cross stress, so the spring steel is required to have high tensile strength, elastic limit, and high fatigue strength. The process requires the spring steel to have a certain degree of hardenability and not be easy to decarburize. Carbon spring steel with good surface quality is high-quality carbon structural steel with carbon content in the range of .%-.%. Alloy spring steel is mainly silicon-manganese steel. Their slightly lower carbon content mainly depends on increasing the silicon content to improve performance. There are also alloy spring steels made of chrome, tungsten and vanadium. The carbon content of alloy spring steel is between .-.%. The alloying elements added are there. Their function is to improve the hardenability and stability, strengthen the ferrite and refine the particles, and effectively improve the mechanical properties of spring steel. Among them, , and can also improve the high-temperature strength of steel.
After quenching and tempering, spring steel has higher hardness and wear resistance, but has low thermal hardness, poor hardenability, easy deformation, and low plasticity and strength. Used as various tools that require higher hardness and wear resistance, such as simple-shaped molds and punches, metal cutting tools, drilling tools, milling cutters for woodworking, countersunk drills, axes, chisels, longitudinal hand saws, As well as secondary tools such as benchwork assembly tools and rivet dies.
Steel belt products are suitable for shock absorber valve plates, clutch diaphragm springs, air-conditioning compressor valve plates, knitting machine accessories, sinkers, negative films, knitting needles, raw film, various printing scrapers, and endless belts Knives, etc., metal stamping springs, springs, tensile parts and anti-springs are products that require high quality. Material certification reports can be provided in strips according to customer requirements
