High hardness and high wear-resistant spring steel spring steel full hard blued spring steel 55SiMnVB Jia Wang mention ..

Jia Wang spring steel varieties: wear spring steel, high temperature resistant spring steel, tensile spring steel, high elastic spring steel, Hard spring steel, spring steel state, full hard spring steel, 1/2 (semi-hard) spring steel, all soft spring steel, stainless spring steel, spring steel. Spring steel Performance: spring steel under impact, vibration or stress for long-term deposit, 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 carbon spring steel that is the carbon content of WC within 0.6% -0.9% range of high-quality carbon structural steel. Silicomanganese alloy spring steel is mainly the Department of steel, their lower carbon content, mainly by increasing silicon content Wsi improve performance; in addition to Ge, tungsten, vanadium alloy spring steel. In recent years, combined with our resources, and designed according to the requirements of new technology cars, tractors, developed a boron, niobium, molybdenum and other elements on the basis of in silico-manganese steel new steel, 1 65, 70, 85: It is obtained high strength, hardness, yield ratio, but hardenability small, good heat resistance, low ability to withstand dynamic loads and fatigue loads is widely used, but more for the working temperature is not high, a small spring or less important than the Big Spring. As spring 65Mn ingredient cars, tractors, railway vehicles and general machinery is simple, hardenability and mechanical properties, process performance than steel decarburization good, but more sensitive to overheating, temper brittleness, quenching prone Crack low prices, a great amount. Manufacture of various small section flat spring, round spring, spring, etc., can make the valve spring, spring ring, shock absorbers and clutch springs, brake springs and the like. 2. 55Si2Mn, 60Si2Mn, 60Si2MnA silicon content (Wsi) high (upper limit of 2.00%), high intensity, good elasticity. Good temper resistance. Decarburization and graphitization. Hardenability is not high. The main spring steel type, very versatile. Manufacture all kinds of springs, such as cars, motorcycles, tractors leaf springs, coil springs, cylinder valve springs and spring some important work under high stress, severe wear spring. 55Si2MnB because boron, which significantly improved hardenability light, midsize car front suspension springs, Deputy spring. 55Si2MnB our self-developed steel, hardenability, mechanical properties, fatigue performance better than that of steel 60Si2Mn major manufacturers, the good small car leaf spring effect, can also be made of other medium-sectional dimensions of the leaf springs, coil springs . 3. 60Si2CrA 60Si2CrVA high strength spring steel. Hardenability, good heat treatment process performance. Because of the high intensity, should be promptly after spring roll treatment to relieve internal stress load big important manufacturing large springs. 60Si2CrA be prepared Turbine Seal spring, adjusting spring, condenser bearing springs, disc springs and other high pressure pumps. 60Si2CrVA also make a very important steel springs, such as conventional weapons extractors hook spring, spring breakers. 4. 55CrMnA 60CrMnA advantage is good hardenability, additional thermal processing performance, mechanical properties, resistance to decarbonization performance is also a big cross-section of various important springs, such as cars, locomotives large leaf springs, coil springs and the like. 5. 60CrMnMoA hardenability up in various existing spring steel. Mechanical properties, resistance to tempering stability is also good large-scale civil engineering, heavy vehicles, machinery and other large springs used. Plate thickness up to 35mm or more, round diameter of more than 60mm 6. 50CrVA small amount of vanadium to improve flexibility, strength, yield ratio and reduce resistance shells, refined grains, reducing the tendency to decarburization. The carbon content is small, ductility, toughness is good compared to other spring steel. High hardenability, fatigue performance of various important Hao coil springs, particularly suitable for high work stress amplitude fatigue performance demanding springs, such as valve springs, nozzle springs, cylinder expansion ring, valve springs, etc. 7. 60CrMnBA hardenability higher than 60CrMnA various other properties similar to larger leaf springs, coil springs, torsion springs. 8. 30W4Cr2VA high-strength heat-resistant spring steel. Good hardenability. High temperature anti-relaxation and thermal processing performance is also very good temperature resistant spring 500 ~ C or less, such as turbine main steam valve springs, steam seal spring, boiler safety valve spring, 400t boiler disc valve spring. Extending the spring of life and improve the quality of the spring. Features and Scope: It is widely used silicon-manganese spring steel, strength, flexibility and higher hardenability than 55Si2Mn. Suitable for railway vehicles, bear a greater load on the automobile and tractor industry of flat spring or coil spring 30mm or less in diameter, and is also suitable for the production of working temperature below 250 ℃ non-corrosive medium heat springs and alternating load and work under high stress the important roll of large springs. Mechanical Properties: Tensile strength σb (MPa): ≥1568 (160) yield strength σs (MPa): ≥1372 (140) Elongation δ10 (%): ≥5 section shrinkage ψ (%): ≥20 Hardness: hot-rolled, ≤321HB; Cold Drawn + heat treatment, ≤321HB Japan imported spring steel SUP3 SUP6 SUP7 SUP9 SUP9A SUP10 SUP11 SUP12 SUP13 plate, sheet, strip, wire, per rod, square bar, flat, hexagonal rods special specifications Can be customized [popular brands]: Grade common alloy spring steel, chemical composition, heat treatment, mechanical properties and uses are shown in Table 6-4. Common alloy spring steel have 60Si2Mn, 50CrVA, 30W4Cr2VA like. 60Si2Mn steel is the most widely used alloy spring steel, which produce about 80 percent alloy spring steel output. Its strength, hardenability, tempering resistance than the high carbon spring steel, operating temperature up to 250 ℃, the disadvantage is a greater tendency to decarburization, suitable for manufacturing leaf springs and cross-sectional dimensions smaller than the thickness of less than 25mm, 10mm screw spring, the heavy machinery, railway vehicles, cars, tractors have a wide range of applications. 50CrVA mechanical properties of steel and steel 60Si2Mn similar, but higher hardenability, Cr and V in steel can improve the elastic limit, strength, toughness and resistance to tempering, commonly used in the production of heavy load, high temperature and cross-sectional dimensions larger spring. 30W4Cr2VA heat-resistant high-strength spring, the main valve spring for boilers below 500 ℃ work, the turbine steam seal spring. Heat treatment]: [performance]: spring steel with soft semi-hard and full hard state full hard hardness of 40 ~ 48HRC, has high elastic limit and fatigue strength, and a certain plasticity and toughness spring steel use: spring steel is mainly used In locomotives, vehicles, cars, tractors, airplanes and other various coil springs and leaf springs.
