VT machining offers CNC Laser Cutting for 420 Stainless Steel (UNS S42000 / 1.4021-1.4034), typically supplied annealed or hardened. Higher carbon than 410 reaches greater hardness; machined annealed then hardened.
CNC Laser Cutting Notes for 420 Stainless Steel
Fibre-laser cutting of 420 Stainless Steel sheet gives a narrow kerf with minimal burr.
For estimating, a 100 × 100 × 10 mm block of 420 Stainless Steel weighs about 0.77 kg.

How clean are the edges produced by CNC Laser Cutting on 420 Stainless Steel?
Laser cutting leaves 420 Stainless Steel with a narrow kerf and a clean, near burr-free edge and only a small heat-affected zone.
What tolerances can you hold for CNC Laser Cutting 420 Stainless Steel?
Achievable tolerances for 420 Stainless Steel cutting depend on the alloy, geometry and feature size. Laser cutting holds contour tolerances to around ±0.05 mm depending on thickness. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom 420 Stainless Steel parts to my drawing?
Yes. 420 Stainless Steel cutting is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What is CNC Laser Cutting 420 Stainless Steel and how is it done?
CNC Laser Cutting 420 Stainless Steel refers to cNC fiber laser cutting follows a programmed path to cut sheet and plate with a clean, narrow kerf. Applied to 420 Stainless Steel — corrosion resistant, strong and hygienic — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Why is 420 Stainless Steel a good choice for CNC Laser Cutting?
420 Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC Laser Cutting. We tune the process to the alloy so the finished 420 Stainless Steel cutting part meets your dimensional and functional requirements.
