Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a lower-grade stainless steel for high-corrosion environments.Always select 304 stainless steel or higher for applications involving aggressive media or elevated temperatures where corrosion resistance is critical.
Inadequate cleaning of the sheet surface before fabrication.Thoroughly clean the 304 stainless steel sheet to remove oils, dirt, and any contaminants that could affect welding, surface finish, or performance.

Common Applications

  • Pressure vessel fabrication
  • Heat exchanger components
  • High-temperature ducting and manifolds

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE) during handling and fabrication.
  • Ensure proper ventilation when welding or performing high-temperature operations.
