Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard carbon steel cutting tools without proper lubrication, leading to galling and premature tool failure.Employ high-speed steel or carbide tooling specifically designed for stainless steel, and utilize a cutting fluid or coolant.
Inadequate cleaning after fabrication, leaving residual contaminants that can initiate corrosion.Thoroughly degrease and clean the fabricated parts using alkaline cleaners or solvents, followed by rinsing with deionized water.

Common Applications

  • Custom fabrication of machine components
  • Food processing equipment linings
  • Architectural elements requiring corrosion resistance

⚠️ Engineering Warnings

  • Handle with care to avoid sharp edges after cutting or forming.
  • Ensure proper ventilation when performing welding or grinding operations.
