2. Why Stainless Steel?
Stainless steel is a popular material for compression springs due to:
- ਖੋਰ ਪ੍ਰਤੀਰੋਧ: Ideal for harsh environments, including high humidity, water, and chemicals.
- Strength and Durability: Maintains mechanical properties over time, even under repeated stress.
- Temperature Resistance: Withstands high and low temperatures depending on the grade.
- Non-Magnetic Properties: Certain grades (ਪਸੰਦ 316) are non-magnetic, useful in sensitive applications.
Common Stainless Steel Grades:
- 302 ਸਟੇਨਲੇਸ ਸਟੀਲ: Offers excellent corrosion resistance and good mechanical properties. Ideal for general-purpose springs.
- 316 ਸਟੇਨਲੇਸ ਸਟੀਲ: ਸੁਪੀਰੀਅਰ ਖੋਰ ਪ੍ਰਤੀਰੋਧ, especially in marine or chemical environments.
- 17-7 PH ਸਟੀਲ: Heat-treatable for higher strength and hardness.
3. Key Specifications for Long Stainless Steel Compression Springs
When selecting or designing long stainless steel compression springs, consider the following specifications:
1. ਬਸੰਤ ਮਾਪ:

5. ਡਿਜ਼ਾਈਨ ਵਿਚਾਰ
When designing long stainless steel compression springs, follow these key steps:
1. Determine Spring Function:
- Understand the force and deflection requirements.
- Consider the spring's intended application and environment.
2. Calculate Spring Dimensions:
- Use the spring constant formula: k=G⋅d48⋅n⋅D3k = \frac{G \cdot d^4}{8 \cdot n \cdot D^3}k=8⋅n⋅D3G⋅d4 Where:
- GGG = Shear modulus of the material.
- ddd = Wire diameter.
- nnn = Active coils.
- DDD = Mean coil diameter (ਦੇ - wire diameter).
3. ਤਣਾਅ ਵਿਸ਼ਲੇਸ਼ਣ:
- Ensure the spring can handle the maximum load without exceeding the material's yield strength.
- Verify the spring's performance using the Hooke's Law: F=k⋅ΔxF = k \cdot \Delta xF=k⋅Δx
4. ਸਮੱਗਰੀ ਦੀ ਚੋਣ:
- Match the stainless steel grade to the application. ਉਦਾਹਰਣ ਲਈ:
- ਵਰਤੋ 302 ਸਟੇਨਲੇਸ ਸਟੀਲ for general purposes.
- ਵਰਤੋ 316 ਸਟੇਨਲੇਸ ਸਟੀਲ for marine or chemical exposure.
5. ਨਿਰਮਾਣ ਪ੍ਰਕਿਰਿਆ:
- ਕੋਇਲਿੰਗ: Stainless steel wires are wound into helical shapes.
- ਗਰਮੀ ਦਾ ਇਲਾਜ: Improves strength and elasticity.
- ਸਰਫੇਸ ਫਿਨਿਸ਼ਿੰਗ: Passivation or coating for enhanced corrosion resistance.
