Spring steel varieties: wear spring steel high-temperature tensile spring steel spring steel spring steel Hard high elastic spring steel spring steel spring steel 1/2 full hard state (semi-hard) spring steel totally flexible spring steel stainless spring steel spring steel with spring steel spring steel spring steel bar round spring steel wire spring steel spring wire manganese steel 1. carbon spring steel (ie, non-alloy spring steel) its cheap but poor hardenability, less suitable for the cross-sectional dimension Non-important spring, which SK5 most commonly used. Carbon spring steel carbon content (mass fraction) is generally 0.62% to 0.90%. In accordance with its manganese content is divided into general manganese content (mass fraction) (0.50% - 0.80%) as 65,70,85 and high manganese content (mass fraction) (0.90 to 1.20%), as 65Mn categories. 2. The main plus alloy spring steel according to the different types of alloying elements can be divided into two categories: Si-Mn and Cr-based system spring steel spring steel. The former high hardenability than steel, the price is not very expensive, so the most widely used, mainly for the cross-sectional dimension of not more than 25mm of various types of springs, 60Si2Mn is a typical representative; the latter is better hardenability, mechanical properties high spring surface easy removal, but the price is relatively high, generally used for larger cross-sectional dimensions important spring, 50CrVA is a typical representative. Alloy spring steel is based on the carbon steel, through appropriate one or more alloying elements added to improve the mechanical properties of steel, hardenability and other properties to meet the required performance of manufacturing all kinds of spring steel. The basic composition series alloy spring steel have, silico-manganese spring steel, chrome silicon spring steel, chrome-manganese spring steel, chrome vanadium spring steel, tungsten chrome vanadium spring steel. On the basis of these series, there are a number of brands in order to improve certain aspects of their performance and added molybdenum, vanadium or boron and other alloying elements. - In addition, the Xiangyun also from other types of steel, such as high-quality carbon structural steel, carbon tool steel, high speed tool steel, stainless steel, select some grades as spring steel. Spring steel refers to steel due to the elasticity in the quenched and tempered condition, and specifically for the manufacture of springs and elastic components. Spring steel depends on its ability to elastic deformation, that is, within the specified range, the ability to withstand a certain elastic deformation so that the load does not appear permanent deformation after load removal spring steel should have good overall performance, such as mechanics properties (especially elastic limit, ultimate strength, yield ratio), ballistic reduce performance (ie anti-elastic properties decreased, also known as sag resistance), fatigue properties, hardenability, physical and chemical properties (heat resistance, low temperature, anti-oxidation, corrosion, etc.). To meet these performance requirements. Spring steel with excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), the exact shape and size. Spring under the impact, vibration or stress for long post, it requires a high spring steel tensile strength, elastic limit, high fatigue strength in the process requires a certain degree of spring steel hardenability, easy removal, good surface quality etc., carbon spring steel that is the carbon content of WC within the range of 0.6% -0.9% of high-quality carbon structural steel alloy spring steel is mainly silico-manganese-based steel, lower their carbon content, mainly by increasing silicon content Wsi improve performance; in addition to Ge, tungsten, vanadium alloy spring steel. Alloy spring steel carbon content between 0.45-0.75%, the added alloying elements Mn, Si, W, V, Mo, etc., and their role is to enhance hardenability and back to stability, strengthened ferritic and fine particles, effectively improve the mechanical properties of spring steel, in which Cr, W, Mo can improve the high temperature strength of steel. After quenching and tempering spring steel has high hardness and wear resistance, but low thermal rigid, hardenability poor, deformation, low ductility and strength. Used needs to have a high hardness and wear resistance of various tools, such as the shape of a simple mold and punch, metal cutting tools, drilling tools, woodworking cutters, cutters, axes, chisels, hand saws longitudinal and fitter assembly tools, riveting die and other minor tools. Steel products for shock absorber valves, clutch diaphragm spring, air compressor valve, knitting machine parts, sinkers, Kazakhstan negative, knitting needles, Sinker, a variety of printing scraper, ring knives and other metal stamping shrapnel, spring, spring, stretching pieces, anti-spring product quality requirements.
