VT machining offers CNC Routing for 431 Stainless Steel (UNS S43100 / 1.4057), typically supplied hardened & tempered. Best corrosion resistance of the martensitic grades with high toughness.
CNC Routing Notes for 431 Stainless Steel
Routing is only economical in 431 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 431 Stainless Steel weighs about 0.77 kg.

What is CNC Routing 431 Stainless Steel and how is it done?
CNC Routing 431 Stainless Steel refers to cNC routing cuts profiles and openings in sheet and plate at high feed rates with a rotating router bit. Applied to 431 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 431 Stainless Steel a good choice for CNC Routing?
431 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 431 Stainless Steel machining part meets your dimensional and functional requirements.
Can VT machining make custom 431 Stainless Steel parts to my drawing?
Yes. 431 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 is the typical lead time and minimum order for CNC Routing 431 Stainless Steel?
CNC Routing prototypes for 431 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.
Does CNC Routing 431 Stainless Steel require dedicated tooling?
Most 431 Stainless Steel machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
