Characteristic
1. Weldability Parameters:
- 304 stainless steel exhibits excellent weldability, allowing for a variety of welding methods such as arc welding, resistance welding, and gas welding.
- Welding current: 100-120 AC or 100-160 DC (amperes)
- Shielding gas: Argon or a mixture of argon and hydrogen
2. Heat Affected Zone (HAZ) Considerations:
- The HAZ of 304 stainless steel during welding is relatively small, minimizing the risk of sensitization and corrosion issues.
- Preheating is generally not required for thin sections, but it may be beneficial for thicker materials.
3. Post-Weld Annealing:
- Annealing after welding helps restore corrosion resistance and mechanical properties.
- Temperature: 1,010-1,120°C (1,850-2,050°F) for 30 minutes per 25 mm thickness.
4. Advantages of 304 Stainless Steel Welding:
- Corrosion Resistance: 304 stainless steel maintains corrosion resistance even after welding.
- Versatility: Suitable for a wide range of applications due to its compatibility with various fabrication processes.
- Aesthetics: Provides an attractive, polished appearance after welding.
5. Disadvantages of 304 Stainless Steel Welding:
- Sensitization: Prolonged exposure to elevated temperatures can lead to sensitization, reducing corrosion resistance.
- Hot Cracking: Susceptible to hot cracking in specific welding conditions, especially with high sulfur content.
