VT machining provides CNC Punching 420 Stainless Steel for customers who need accurate, repeatable 420 Stainless Steel components. The machinability of 420 Stainless Steel is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, so we set the operation up specifically for this grade.
CNC Punching Capability for 420 Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 420 Stainless Steel with CNC Punching
The machinability of 420 Stainless Steel is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing. For CNC Punching we select tooling, feeds and coolant to match, keeping the 420 Stainless Steel workpiece stable and the result accurate.
