Spring steel | Xufeng Hardware Factory (Certified) | spring Xufeng provided by Dongguan City Hardware Products Factory. Xufeng Dongguan City Hardware Products Factory (www.dglijing168.com) is specialized in the "spring-like, lathe parts class, stamping class, spring, torsion spring, retainer, battery spring, shaped bomb" of the enterprise, the company uphold "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Miss Liu. Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stampings business compression spring, the factory has advanced technology and equipment stainless steel springs, modern plant and professionals, products sold around the world. Elongated flat spiral spring is made of materials, such as cross-sectional plane around the helical springs, flat spiral spring production is relatively simple, its rigidity is small, typically work under static load. Since the number of windings can be much deformation angle is large, more energy can be stored in a smaller volume. Its sectional shape may be rectangular material (steel) or circular (steel). Flat spiral spring contact according to the adjacent ring is divided into two categories: non-contact and contact type. We are designing a suitable home use fitness rowing when its damping issues were discussed multi-program comparison, the outer ends of the hinge finally adopted a non-contact type flat spiral spring as a junior after its use to achieve the desired damping effect. (You can think about oh)! ! ! Xufeng Dongguan City Hardware Products Factory is a professional production of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. Spring steel is designed to manufacture all kinds of springs and elastic components or key performance requirements similar structural components. Common Table 12-10 for spring steel grades, performance characteristics and main uses of commonly used spring steel, its composition, heat treatment and mechanical properties may refer to relevant national standards (eg GB1222-1984). Table 12-10 spring steel grades used primarily performance characteristics and uses of the performance characteristics of the type of steel production should use ordinary carbon spring steel 65 Mn amount of hardness, strength, yield ratio disc springs, but poor hardenability, heat resistance bad spring, and the ability to withstand fatigue loads dynamic load low low prices, and more used in the operating temperature is not high, a small spring <12mm or larger unimportant spring 7085 high Mn content 65Mn hardenability, mechanical properties superior to carbon steel, but more sensitive to overheating lower prices, the amount is large, the manufacture of various small section <15mm flat spring, the spring, damper and spring clutch, brake shaft alloy spring steel Si-Mn system 55Si2Mn strength high, good flexibility, good resistance to tempering stability; but easy decarbonization and graphitization!
