Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard fasteners not rated for stainless steel environments.Utilize stainless steel fasteners (e.g., 304 or 316 grade) to prevent galvanic corrosion and maintain material integrity.
Improper cutting techniques leading to work hardening or contamination.Employ appropriate cutting methods such as abrasive cutting or plasma cutting with proper coolant and cutting speeds. Ensure tools are clean and free from carbon steel contamination.

Common Applications

  • Custom fabrication of machine guards and enclosures
  • Industrial shelving and structural components
  • Prototyping and specialized equipment manufacturing

⚠️ Engineering Warnings

  • Handle with care to avoid sharp edges. Appropriate personal protective equipment (PPE) is recommended.
  • Avoid contact with highly corrosive chemicals or materials that can cause pitting or crevice corrosion, even with 304 grade.
