Effect of Heat Treatment Process on Mechanical Properties

In order to obtain this T strengthening method at the same time, vanadium and niobium are added to AISI 9260 (0.60C, 0.20Si, 0.85Mn) steel to develop A precipitation-strengthened spring steel for a suspension spring of a car. This steel has a precipitation strengthening effect at 850 degrees and tempering at 550 degrees. Effect of heat treatment on fatigue resistance of spring Jul 25, 2010 · The 60Si2CrVAT from two heats (Table 1). strength and toughness of the spring steel have been in- Steel bars were cut into rods 120 mm long, heat treated, creased too. A production of special spring steel 60Si2CrVAT and ground to a diameter of 17.50 mm. Then the rods were has been organized for high-speed trains [1 7]. subjected to fatigue tests. Effect of heat treatment on fatigue resistance of spring Jul 25, 2010 · details. Fatigue resistance of heat-treated spring steel 60Si2CrVAT due to three-point bending with step growth in the load is studied. The microstructure of the steel and fatigue fracture surfaces are analyzed by the method of scanning electron microscopy. The possibilities of raising the fatigue resistance of springs used in high-speed freight bogies are considered.

Mechanical properties of high strength spring steel

60Si2CrVAT,developed on the basis of the spring steel grade of 60Si2CrVA in conformance according to Chinese Standard,is a tailor-made steel grade by the Ministry of Railways.The main differences between 60Si2CrVAT and 60Si2CrVA are the request for high purity large elongation and reduction of area of 60Si2CrVAT,in order to meet the severe environment and longer servicinglife 60Si2CrVAT Special SpringsSpecial Springs catalog is now enriched by the new pressure reducer capable of supporting inlet pressures up to 300 bar / 4350 psi. Special Springs gas springs the only ones with OSAS, USAS and OPAS as standard, for the safest experience in the nitrogen world.

The Numerical Simulation of Decarburization of 60Si2CrVA

In according to the DEFORM-3D software, we simulated the decarburization depth of the 60Si2CrVA spring steel in heat treatment, optimized the process parameters with the simulation results. The result of the research illustrated that the actual decarburization depth is consistent with the simulation result, which demonstrate DEFORM-3D has a practical guide for the process of heat treatment. spring steelspring steel. Spring steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic components.It can be divided into ordinary alloy spring steel and special alloy spring steel according to the performance requirements and using conditions.Spring steel has excellent comprehensive properties, with excellent metallurgical quality (high purity and uniformity China Customized 60si2crva Spring Steel With Polished Compared with silicon-manganese steel, 60Si2CrVA spring steel bar has higher tensile strength and yield strength when its plasticity is similar to that of silicon-manganese steel, and the steel has greater hardenability and temper brittleness. 60 si2crva spring steel is used to work under high stress and temperature in the spring under 300 ~ 350 , such as the governor spring, steam turbine gland
