| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a standard stainless steel (e.g., 304) in highly corrosive environments. | Select 316 stainless steel for superior resistance to chlorides and aggressive media. |
| Over-tightening, leading to thread stripping or material fatigue. | Always use a torque wrench set to the manufacturer's recommended value. |
