Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard carbon steel cutting tools, which can lead to contamination and reduced corrosion resistance.Employ dedicated stainless steel cutting tools and ensure thorough cleaning of all equipment.
Improper welding procedures leading to carbide precipitation and sensitization, compromising corrosion resistance.Utilize low-carbon grades (e.g., 304L if available and appropriate for the application) or follow post-weld heat treatment procedures if full 304 is used and sensitization is a concern.

Common Applications

  • Custom heat exchanger fabrication
  • Industrial furnace and oven components
  • High-temperature ducting and exhaust systems

⚠️ Engineering Warnings

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