VT machining offers CNC 5-Axis Machining for 302 Stainless Steel (UNS S30200 / 1.4319), typically supplied annealed or spring temper. Higher carbon than 304 gives more strength after cold work; common spring-wire grade.
CNC 5-Axis Machining Notes for 302 Stainless Steel
Multi-axis machining lets 302 Stainless Steel parts be completed in one or two setups, which improves feature-to-feature accuracy.
For estimating, a 100 × 100 × 10 mm block of 302 Stainless Steel weighs about 0.79 kg.

Can VT machining make custom 302 Stainless Steel parts to my drawing?
Yes. 302 Stainless Steel machining 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 tolerances can you hold for CNC 5-Axis Machining 302 Stainless Steel?
Achievable tolerances for 302 Stainless Steel machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
Why is 302 Stainless Steel a good choice for CNC 5-Axis Machining?
302 Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC 5-Axis Machining. We tune the process to the alloy so the finished 302 Stainless Steel machining part meets your dimensional and functional requirements.
What surface finish is achievable on 302 Stainless Steel with CNC 5-Axis Machining?
Surface finish on 302 Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
