VT machining offers CNC Routing for 347 Stainless Steel (UNS S34700 / 1.4550), typically supplied annealed. Niobium-stabilised alternative to 321, better for welded high-temperature service.
CNC Routing Notes for 347 Stainless Steel
Routing is only economical in 347 Stainless Steel for thin sections; for thicker plate we usually recommend milling, laser or waterjet instead.
For estimating, a 100 × 100 × 10 mm block of 347 Stainless Steel weighs about 0.80 kg.

What surface finish is achievable on 347 Stainless Steel with CNC Routing?
Surface finish on 347 Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What material thickness or size range suits CNC Routing 347 Stainless Steel?
We machine 347 Stainless Steel across a broad size range; share your part envelope for confirmation.
How clean are the edges produced by CNC Routing on 347 Stainless Steel?
Machined 347 Stainless Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What is the typical lead time and minimum order for CNC Routing 347 Stainless Steel?
CNC Routing prototypes for 347 Stainless Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Routing 347 Stainless Steel?
Achievable tolerances for 347 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 347 Stainless Steel a good choice for CNC Routing?
347 Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC Routing. We tune the process to the alloy so the finished 347 Stainless Steel machining part meets your dimensional and functional requirements.
