304 Stainless Steel Properties

304 stainless steel is the most commonly used austenitic stainless steel alloy, known for its corrosion resistance, strength, and weldability. It consists of:

• 18% Chromium (Cr) – Provides oxidation and rust resistance.

• 8% Nickel (Ni) – Enhances toughness and ductility.

• Low Carbon Content – Improves weldability and reduces carbide precipitation.

Key Advantages of 304 SS Flanges:

✅ Corrosion Resistance: Performs well in moist environments, chemical industries, and marine conditions.
✅ High-Temperature Tolerance: Withstands up to 870°C (1598°F) in continuous operations.
✅ Non-Magnetic Properties: Remains non-magnetic in annealed conditions.
✅ Versatile Applications: Used in piping, food processing, medical equipment, and industrial machinery.

Types of Stainless Steel Flanges

1. Weld Neck Flange (WN)

• Best for high-pressure, high-temperature applications.

• Provides excellent mechanical strength.

2. Slip-On Flange (SOF)

• Easy installation, as it slides over the pipe before welding.

• Suitable for low to medium-pressure systems.

3. Blind Flange (BL)

• Seals pipeline ends, preventing leaks.

• Used for testing and system shutdowns.

4. Threaded Flange (THF)

• Screws onto pipes without welding.

• Used in low-pressure plumbing systems.

5. Lap Joint Flange (LJF)

• Allows easy alignment and dismantling, used with stub ends.

• Ideal for frequent maintenance applications.
