Введение
If you’re in manufacturing or materials sourcing, you’ve likely encountered both отожженная стальная полоса и quenched & tempered steel strip. While both are types of heat treated steel, they serve very different functions depending on the mechanical requirements of your end product.
This article breaks down the differences between these two processes and helps you choose the right material for your specific application.
1. What Is Heat Treated Steel Strip?
Термическая обработка is the process of altering the physical and mechanical properties of steel through heating and cooling cycles. The goal is to improve properties such as:
- Твердость
- Сила
- Elasticity
- Пластичность
- Обрабатываемость
There are two main types of heat treatment commonly used in steel strip manufacturing: отжиг и закалка + закалка.
2. What Is Annealed Steel Strip?
Отожженная стальная полоса is produced by heating the steel to a specific temperature (usually around 700–900°C) and then cooling it slowly, typically in a controlled furnace atmosphere.
? Ключевые особенности:
- ✅ Soft and ductile
- ✅ Excellent for cold forming, stamping, and bending
- ✅ Гладкая поверхность
- ✅ Easy to cut or machine
? Лучше всего для:
- Deep-drawn parts
- Precision bending components
- Decorative hardware
- Electrical parts that require forming
3. What Is Quenched & Полоса из закаленной стали?
This process involves two stages:
- закалка – Rapidly cooling the steel after heating to harden it
- Закалка – Reheating to a lower temperature to adjust toughness and reduce brittleness
? Ключевые особенности:
- ✅ High hardness and wear resistance
- ✅ Excellent elasticity and springback
- ✅ Сильная усталостная устойчивость
- ✅ Dimensional stability during stamping/forming
? Лучше всего для:
- Springs and clips
- Blades and saws
- Automotive clamps
- Industrial tools under stress
4. Quick Comparison Table
| Property | Отожженная стальная полоса | Закаленный & Полоса из закаленной стали |
|---|---|---|
| Твердость | Low | Medium to High (up to HRC 60) |
| Пластичность | Высокий | Moderate |
| Elasticity | Low | Высокий |
| Обрабатываемость | Easy | Requires care |
| Ideal Use | Forming, shaping | Stress-bearing, wear-prone parts |
5. Choosing the Right Material: Key Considerations
- If you need flexibility and easy forming → go for annealed strip
- If your product must withstand high stress, load, or wear → choose tempered strip
- For secondary processing (like punching or stamping), consider dimensional stability and internal stress
- Always check if the hardness range and tensile strength match your application’s safety standards
