2. Raw material is SUP9
3. The free arch is 121mm, the development length is 1350
4. The painting use electrophoretic painting.
Our advantage :
1.We have cooperated with many OEM company in International market .
2. We have more than 5000 types of leaf springs .
3. We use electrophoretic spray paint . the finish and the ability of anti-rust is better than normal paint from other factory .
A leaf spring consists basically of a beam, usually of flat strip, e.g. a cantilever or simply supported beam, subjected to a load to give a desired deflection proportional to the load.
Is there only SUP7 material available?
There are four common types of special steel materials for leaf springs, namely SUP7, SUP9, 50CrVA, and 51CrV4
Choosing the best material among SUP7, SUP9, 50CrVA, and 51CrV4 for steel plate springs depends on various factors such as mechanical properties required, operating conditions, and cost considerations. Here's a comparison of these materials:
1.SUP7 and SUP9:
These are both carbon steels commonly used for spring applications.SUP7 and SUP9 offer good elasticity, strength, and toughness, making them suitable for general-purpose spring applications.They are cost-effective options and relatively easy to manufacture.
However, they may have lower fatigue resistance compared to alloy steels like 50CrVA or 51CrV4.
2.50CrVA:
50CrVA is an alloy spring steel containing chromium and vanadium additives.It offers higher strength, hardness, and fatigue resistance compared to carbon steels like SUP7 and SUP9.50CrVA is suitable for applications requiring higher performance and durability under cyclic loading conditions.
It may be preferred for heavy-duty or high-stress applications where superior mechanical properties are critical.
3. 51CrV4:
51CrV4 is another alloy spring steel with chromium and vanadium content.It offers similar properties to 50CrVA but may have slightly higher strength and toughness.51CrV4 is commonly used in demanding applications such as automotive suspension systems, where excellent fatigue resistance and durability are essential.
While 51CrV4 may offer superior performance, it could come at a higher cost compared to carbon steels like SUP7 and SUP9.
In summary, if cost is a significant factor and the application does not require extreme performance, SUP7 or SUP9 can be suitable choices. However, for applications demanding higher strength, fatigue resistance, and durability, alloy steels like 50CrVA or 51CrV4 may be preferable. Ultimately, the selection should be based on a careful consideration of the specific requirements and constraints of the application.
