Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incompatible welding consumables that can lead to intergranular corrosion.Employ E308L or ER308L filler metals specifically designed for 304 stainless steel to maintain corrosion resistance.
Insufficient cleaning of the material prior to welding or assembly, leading to surface contamination.Thoroughly degrease and clean the stainless steel surfaces using approved solvents and non-abrasive tools before any fabrication or installation steps.

Common Applications

  • Heat Exchanger Fabrication
  • Industrial Furnace Linings
  • Ductwork for High-Temperature Environments

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling and fabricating stainless steel.
  • Avoid using carbon steel tools or brushes on stainless steel surfaces to prevent cross-contamination and galvanic corrosion.
