We can customize any size you need For personalized products, please provide the parameters you should customer service first, verify the unit price, after which place an order For example, for $10, you could possibly take 10 copies of this hyperlink and point out the scale
The spring is non-standard
The elasticity of the spring is dependent upon the size, so the alternative of length is
principal
Actual taking pictures
Quenching treatment, stable elasticity, demanding to interrupt
Easy utility of eventualities
The distinction between spring metal and 65 manganese steel
1、 Performance Characteristics Comparison
1 Hardness and put on resistance
65 Manganese Steel: Higher hardness (≤ 302HB after hot rolling, ≤ 321HB after warmth treatment), better wear resistance, compatible for top wear resistant eventualities
Spring steel: has lower hardness, yet higher elastic limit and fatigue resistance, suitable for elastic components with widespread deformation
2 Heat medicine characteristics
sixty five manganese steel: has overheating sensitivity and tendency in direction of tempering brittleness, and is liable to cracking after water quenching
Spring steel: The heat medication process is extra steady and appropriate for production springs with complex shapes
2、 Differences in utility eventualities
1 sixty five manganese steel
Wear resistant parts: similar to grinding machine spindles, precision machine tool screws, railway rails, etc
High power springs: spiral springs, spring washers, etc with a diameter of ≤ 20mm
2 Spring metal
Elastic components: leaf springs, coil springs, valve springs, and many others for automobiles and tractors
Precision springs: mainspring, seat cushion spring, bloodless drawn metallic cord cold coil spring, and so forth
3、 Summary and choice suggestions
High power and put on resistance are required: 65 manganese metal is favored (such as wear-resistant gears and tune components)
High elasticity and fatigue resistance are required: Spring steel (such as car leaf springs and precision springs) is preferred
