306 لوحة الفولاذ المقاوم للصدأ
“306 stainless steel plate” is generally used as a market reference for a higher-grade austenitic stainless steel with improved corrosion resistance compared to 304. It typically features higher nickel content and sometimes molybdenum addition, making it suitable for chemical, البحرية, and high-corrosion industrial environments where standard stainless steels are not sufficient.
- وصف
“306 stainless steel plate” is not a standard widely recognized AISI/ASTM stainless steel grade. In most industrial and international supply chains, this term is often used in error or as a market reference for high-alloy austenitic stainless steels similar to 304/316 families, especially materials with improved corrosion resistance and stability in chloride environments.
In many practical cases, buyers referring to “306 stainless steel” are actually targeting enhanced austenitic stainless steels with higher nickel or molybdenum content than 304.
التركيب الكيميائي (Typical High-Alloy Austenitic Reference)
منذ 306 is not a strict standardized grade, the composition below reflects a common engineering interpretation of upgraded 300-series stainless steel used in industry:
| عنصر | محتوى (%) |
|---|---|
| الكروم (كر) | 17.0–19.0 |
| النيكل (في) | 10.0-14.0 |
| الموليبدينوم (شهر) | 2.0-3.0 (optional, depending on variant) |
| الكربون (ج) | ≥ 0.08 |
| المنغنيز (من) | ≥ 2.00 |
| السيليكون (و) | ≥ 1.00 |
| الفوسفور (ص) | ≥ 0.045 |
| الكبريت (س) | ≥ 0.03 |
| حديد (الحديد) | توازن |
الخواص الميكانيكية
High-alloy austenitic stainless steels in this category provide balanced strength and excellent toughness.
| ملكية | القيمة النموذجية |
|---|---|
| قوة الشد | 520-750 ميجا باسكال |
| قوة العائد | ≥ 205 الآلام والكروب الذهنية |
| استطالة | ≥ 40% |

Main Performance Features
1. مقاومة ممتازة للتآكل
This material is designed for environments requiring strong resistance to:
- Chloride exposure
- Moist marine atmosphere
- Chemical processing conditions
- Acidic industrial environments
If molybdenum is included, resistance to pitting and crevice corrosion is significantly improved.
2. Good High-Temperature Stability
The alloy maintains stable mechanical performance under moderate elevated temperatures, making it suitable for:
- مبادلات حرارية
- أفران صناعية (non-extreme zones)
- معدات المعالجة الحرارية
3. Excellent Formability and Weldability
مثل غيرها من الفولاذ المقاوم للصدأ الأوستنيتي, it provides:
- Easy welding (تيج, أنا, إلخ.)
- Good deep drawing capability
- Excellent bending performance
- Stable structure without heat treatment hardening
4. Non-Magnetic or Weakly Magnetic
في حالة صلب, it is generally non-magnetic, which is useful for precision equipment and industrial applications.
Common Applications of “306 Stainless Steel Plate”
Because it is interpreted as a high-performance austenitic stainless steel, it is commonly used in:
- معدات المعالجة الكيميائية
- Heat exchanger plates
- مكونات الهندسة البحرية
- Desalination systems
- آلات تجهيز الأغذية
- المعدات الصيدلانية
- Storage tanks and pressure vessels
- Architectural structures in corrosive environments
- Pump and valve components
- أنظمة الأنابيب الصناعية
