Stainless steel flanges are known for their superior qualities, including:
Corrosion Resistance – Resists rust and oxidation, making them ideal for harsh environments.
High Strength – Withstands extreme pressure and temperature conditions.
Durability – Long lifespan with minimal maintenance requirements.
Hygienic Properties – Non-porous surface prevents bacterial growth, suitable for food and pharmaceutical industries.
Aesthetic Appeal – Polished finish maintains a clean, professional appearance.
Below is a detailed breakdown of common stainless steel flange material grades and their properties:
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Hardness (HB) | Primary Applications |
|---|---|---|---|---|
| 304 | 515 | 205 | 201 | Food processing, chemical industry |
| 316 | 515 | 205 | 217 | Marine, pharmaceutical, high-corrosion environments |
| 316L | 485 | 170 | 200 | Welded applications, acidic conditions |
| 321 | 515 | 205 | 217 | High-temperature settings (e.g., exhaust systems) |
| 347 | 515 | 205 | 201 | Aerospace, thermal power plants |
Stainless steel flanges offer superior corrosion resistance, longer lifespan, and better performance in extreme environments compared to carbon steel. They are also more hygienic, making them ideal for food, medical, and chemical industries.
Selecting the right grade depends on environmental factors. For general use, 304 is sufficient. In highly corrosive or marine environments, 316/316L is preferred. For high-temperature applications, 321 or 347 grades are recommended.
Yes, stainless steel flanges are weldable, but the process requires expertise to prevent issues like carbide precipitation (in grades like 304). Low-carbon grades like 316L are easier to weld without compromising corrosion resistance.
Stainless steel flanges are versatile, durable, and resistant to harsh conditions, making them indispensable in industrial piping systems. By understanding their material properties and specifications, you can select the right flange for your needs from Zhejiang Shuangneng Steel Industry Co., Ltd.. For custom requirements, consult with a trusted manufacturer to ensure optimal performance and longevity.
