Comparison of stainless steel pipe grades
Our factory provides a wide range of options to meet various applications. The table below offers a clear comparison of common grades we manufacture:
| Grade | Corrosion Resistance | Temperature Resistance | Common Applications |
|---|---|---|---|
| 201 | Moderate | Up to 600°C | Decorative, kitchen equipment |
| 304 | High | Up to 870°C | Food processing, architectural, chemical equipment |
| 316 | Excellent (with molybdenum) | Up to 925°C | Marine, pharmaceutical, petrochemical |
| 321 | High | Stabilized for high temperatures | Heat exchangers, aerospace |
| 409 | Good | High oxidation resistance | Automotive exhaust systems |
| 904L | Superior | High performance in acids | Chemical processing, offshore oil |
Factors to consider before choosing a stainless steel pipe
Our customers often ask what should be evaluated before selecting a specific grade. Based on our experience, the following factors are the most important:
1. Environmental exposure: saltwater, acidic chemicals, or humidity
2. Mechanical stress: pressure, vibration, and load requirements
3. Temperature fluctuations: continuous or intermittent high heat
4. Budget considerations: balancing cost with performance needs
Guangfeng emphasizes that the wrong selection can lead to premature wear, safety risks, and increased replacement costs. Our team helps each client evaluate all these points thoroughly.
FAQs: How to choose the right grade of stainless steel pipe for my application?
Q1: How to choose the right grade of stainless steel pipe for my application if I need resistance to corrosion in marine environments?
A1: For marine applications, 316 stainless steel is the preferred choice. Our factory recommends this grade because it contains molybdenum, which enhances corrosion resistance against saltwater and chloride environments. It offers long-term reliability and reduces maintenance costs for offshore structures, shipbuilding, and harbor facilities.
Q2: How to choose the right grade of stainless steel pipe for my application when high temperature resistance is required?
A2: When facing high temperature demands, 321 stainless steel is an excellent option. Our engineers guide clients toward this grade because it contains titanium stabilization, which prevents carbide precipitation at elevated temperatures. It is widely used in heat exchangers, aerospace, and industrial heating equipment.
Q3: How to choose the right grade of stainless steel pipe for my application if I need superior resistance to strong acids?
A3: For environments where sulfuric acid or phosphoric acid exposure is common, 904L stainless steel provides the best protection. Our production team highlights this grade for industries like chemical processing and offshore oil, as it offers outstanding resistance to aggressive environments, ensuring maximum service life.
