carbon spring steel (i.e. non-alloy spring steel) its price Cheap but with poor hardenability, it 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, ,, and higher manganese content (mass fraction).
Alloy spring steel
According to the different types of main alloying elements, it can be divided into two major categories: series spring steel and series spring steel. The former has higher hardenability than carbon steel and is not very expensive, so it is the most widely used. It is mainly used for various types of springs with cross-sectional dimensions not larger than
and is its typical representative. The latter has better hardenability and comprehensive mechanics. It has high performance and the spring surface is not easy to decarburize, but the price is relatively high. It is generally used for important springs with large cross-section sizes and is its typical representative. Alloy spring steel 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 added alloying elements such as molybdenum, vanadium or boron in order to improve some 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, within a specified range, the ability to elastically deform allows it to 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 ratio), anti-elasticity loss performance (i.e. resistance to elasticity loss, also known as anti-relaxation performance), fatigue properties, 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. , good surface quality, etc. Carbon spring steel is a high-quality carbon structural steel with a carbon content within the range. Alloy spring steel is mainly a silicon-manganese steel type. Their carbon content is slightly lower, and the performance is mainly improved by increasing the silicon content. In addition There are also alloy spring steels of chrome, tungsten and vanadium. The carbon content of alloy spring steel is in the middle. The added alloying elements are,,,,, etc. Their function is to improve the hardenability and return stability, strengthen the ferrite and refine the particles, effectively improving the properties of spring steel. Mechanical properties, including , , and , can also improve the high temperature strength of steel.
Spring steel has higher hardness and wear resistance after quenching and tempering, but has low thermal hardness, poor hardenability, easy deformation, and low plasticity and strength. Used as various tools that require high hardness and wear resistance, such as molds and punches with simple shapes, metal cutting tools, drilling tools, milling cutters for woodworking, countersunk drills, axes, chisels, and longitudinal hand saws , and 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 Products such as knives, metal stamping shrapnel, springs, springs, tensile parts, and anti-springs require high quality. Can be divided into strips according to customer requirements and provide material certification report
