Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard cutting tools not rated for thick stainless steel.Employ carbide-tipped or diamond-coated cutting tools specifically designed for machining thick stainless steel to prevent tool damage and ensure clean cuts.
Inadequate support during fabrication, leading to warping or stress points.Utilize sufficient fixturing and support systems during welding, bending, or other fabrication processes to maintain dimensional stability and prevent material fatigue.
