And more preferential. Measuring tool Vernier caliper Specification of parameter drawing Product name :Spring steel single hook springThe spring is non-standardThe elasticity of the spring is determined by the size, so the choice of size is important.Actual shootingQuenching treatment, strong elasticity, not easy to break.Easy application of scenarios The difference between spring steel and 65 manganese steel 1, Performance Characteristics Comparison1. Hardness and wear resistance65 Manganese Steel: Higher hardness ( 302HB after hot rolling, 321HB after heat treatment), better wear resistance, suitable for high wear resistant scenarios.Spring steel: has lower hardness, but better elastic limit and fatigue resistance, suitable for elastic components with frequent deformation.2. Heat treatment characteristics65 manganese steel: has overheating sensitivity and tendency towards tempering brittleness, and is prone to cracking after water quenching.Spring steel: The heat treatment process is more stable and suitable for manufacturing springs with complex shapes.2, Differences in application scenarios1. 65 manganese steelWear resistant parts: such as grinding machine spindles, precision machine tool screws, railway rails, etc.High strength springs: spiral springs, spring washers, etc. with a diameter of 20mm.2. Spring steelElastic components: leaf springs, coil springs, valve springs, etc. for automobiles and tractors.Precision springs: mainspring, seat cushion spring, cold drawn steel wire cold coil spring, etc.3, Summary and selection suggestionsHigh strength and wear resistance are required: 65 manganese steel is preferred (such as wear-resistant gears and track components).High elasticity and fatigue resistance are required: Spring steel (such as automotive leaf springs and precision springs) is preferred.is_customized : YesModel Number : WTSZBXLH251003Load Type : ExtensionStyle : SpiralDIY Supplies : MetalworkingMaterial : SteelOrigin : Mainland ChinaUse : FURNITUREsprunki : sprunkiMechanical spring : Mechanical springspring : springsprings : springspilates : pilatesCar accessories : Car accessoriesdock : dockstretching spring : stretching springTension spring : Tension spring,Tension springTube bending : Tube bendingSteel springs : Steel springsspring for door handle : spring for door handledoor handle spring : door handle springressort : ressort
