- Описание
301 stainless steel plate is an austenitic chromium-nickel stainless steel known for its excellent work hardening ability, высокая прочность после холодной обработки, и хорошая коррозионная стойкость. По сравнению с 304 нержавеющая сталь, 301 can achieve significantly higher strength levels through cold deformation, making it widely used in spring components, структурные части, and high-strength sheet applications.
Химический состав 301 Пластина из нержавеющей стали
The alloy design is similar to 304 but with slightly lower chromium and nickel content to enhance work hardening behavior.

| Удлинение | 5–40% (depends on condition) |
| Твердость | ≤ 217 полупансион (отожженный), much higher after cold work |
| Плотность | 7.9 г/см³ |
Основные характеристики производительности
1. Excellent Work Hardening Ability
301 stainless steel is one of the most commonly used grades for work hardening applications. Its strength increases rapidly during cold rolling, штамповка, or bending.
This makes it ideal for:
- Spring components
- High-strength strips
- Structural reinforcement parts
2. Хорошая коррозионная стойкость
301 stainless steel provides corrosion resistance similar to 304 в:
- Atmospheric environments
- Fresh water systems
- Mild industrial conditions
Однако, it is less suitable for strong chloride or marine environments compared to 316.
3. High Strength After Cold Working
Unlike many stainless steels, 301 can reach very high tensile strength after cold rolling, making it suitable for lightweight but strong structural applications.
4. Хорошая формуемость (Отожженное состояние)
In the annealed state, 301 stainless steel has good ductility and can be easily formed into complex shapes before strengthening through cold work.
