Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect cutting tools for thick stainless steel, leading to poor edge quality and tool wear.Utilize high-speed steel or carbide-tipped cutting tools specifically designed for stainless steel, with appropriate speeds and feeds.
Insufficient support during bending or forming, causing unwanted deformation or cracking.Ensure adequate support and use appropriate die and punch configurations to maintain the sheet's integrity during forming processes.

Common Applications

  • Custom fabrication and structural components
  • Food processing equipment and tanks
  • Chemical processing apparatus

⚠️ Engineering Warnings

  • Always wear appropriate personal protective equipment (PPE) when handling and fabricating stainless steel.
  • Ensure proper ventilation when cutting or welding stainless steel to avoid exposure to fumes.
