Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect cutting tools that can cause excessive heat and alter material properties.Employ high-quality cutting equipment (e.g., abrasive waterjet, laser) and follow recommended cutting parameters to minimize heat-affected zones.
Inadequate cleaning after fabrication, leading to contamination and potential corrosion.Thoroughly clean all surfaces post-fabrication using appropriate degreasers and passivation solutions to restore the protective oxide layer.

Common Applications

  • Heat Exchanger Components
  • Ductwork for High-Temperature Air
  • Industrial Oven Linings
  • Thermal Processing Chambers

⚠️ Engineering Warnings

  • Avoid prolonged contact with chloride-rich environments which can lead to pitting corrosion.
  • Ensure proper welding procedures are followed to maintain the material's corrosion resistance, particularly in the heat-affected zone.
