Annealed acceptable machinability, cold plastic deformation is low, poor welding. Under moderate load plate spring, 7-20mm diameter coil springs and spring washers, spring ring. High wear parts, such as grinding spindle, spring chuck. Precision machine screw. Cutter spiral roller bearing ring on the cap. Railroad rails and so on. 60SiCr7 spring steel alloying element content is low, high hardenability, high toughness, ductility, decarburization tendency, tempering stability, thermal processing performance and low cost. 60SiCr7 spring steel, manganese enhance hardenability, φ12mm steel oil can hardenability, surface decarburization tendency smaller than silicon steel, heat treated carbon steel is superior mechanical properties, but there are thermal sensitivity and temper brittleness. Instead of 60SiCr7 spring steel production heavy, medium and small cars, and other medium-sized section of the leaf spring spring and coil springs. ============================================= 60SiCr7 spring steel elements Content Type: 60SiCr7 spring steel for springs or spring-like performance parts steel type. 60SiCr7 spring steel with a high elastic limit ﹑ fatigue limit (especially notched fatigue limit), and a certain degree of impact toughness and ductility. Mainly in the jolts, vibrations and other dynamic loads or long-cycle alternating stress conditions, so in the spring to work under a variety of state should have a good surface quality and high fatigue resistance. 60SiCr7 spring steel in the process performance, subject ﹑ hardened and tempered spring steel, should have a certain hardenability, easy removal, low thermal sensitivity and plasticity higher in the hot state easy to shape, making small size spring The wire should have a uniform hardness and a certain plasticity. Category 60SiCr7 spring steel according to the production method can be divided into hot-rolled and cold drawn spring steel (rolled) spring steel. Hot rolled spring steel coil spring ﹑ including manufacturing torsion bar with a round or trapezoidal steel and manufacturing of flat leaf spring; cold drawn (rolled), including the manufacture of small size spring steel coil spring spring cold drawn steel wire and manufacturing as well as various The cold rolled spring steel strip. 60SiCr7 alloy spring steel, silicon, manganese usually chromium tungsten ﹑ ﹑ ﹑ vanadium molybdenum and trace amounts of boron, the alloy elements can improve the hardenability of steel, manganese and silicon solid dissolved in ferrite, the yield strength can be improved . ﹑ ﹑ Tungsten chromium vanadium steel can increase the elastic limit ﹑ yield ratio and heat resistance. ============================================= One, direct selling, to help customers reduce intermediate links, quality assurance, reasonable prices two, customers can pick and choose their desired length of steel or other requirements three, Swap library missing specifications, eliminating the need for you to run around four hard steel purchases, delivery or arrange transportation, straight hair your location five weekends and holidays, short delivery time six, the sale of steel products, the company responsible for the overall quality tracking, you exclude worries seven, the company can supply raw material of steel attached to steel Book Eight, welcome friends from various circles at home and abroad come to call to discuss! http://www.sk5sk7.com/ (Product Information security check) ======= [casting environmentally friendly materials to build Centennial Strait] =========
