VT machining offers CNC Punching for 430 Stainless Steel (UNS S43000 / 1.4016 / SUS430), typically supplied annealed. Ferritic, nickel-free and magnetic; cheaper than 304 with fair corrosion resistance.
CNC Punching Notes for 430 Stainless Steel
430 Stainless Steel punches cleanly with standard clearance; minimum hole diameter is about the sheet thickness.
For estimating, a 100 × 100 × 10 mm block of 430 Stainless Steel weighs about 0.77 kg.

What surface finish is achievable on 430 Stainless Steel with CNC Punching?
Surface finish on 430 Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What material thickness or size range suits CNC Punching 430 Stainless Steel?
Punching suits 430 Stainless Steel sheet roughly 0.5–6 mm thick, with clearance matched to the gauge.
Does CNC Punching 430 Stainless Steel require dedicated tooling?
Punching uses programmable turret tooling; standard tools cover most patterns, with special tools added for unique forms.
What tolerances can you hold for CNC Punching 430 Stainless Steel?
Achievable tolerances for 430 Stainless Steel punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
