VT machining offers CNC Plasma Cutting for 309S Stainless Steel (UNS S30908 / 1.4833), typically supplied annealed. Low-carbon 309 for better weldability in high-temperature fabrications.
CNC Plasma Cutting Notes for 309S Stainless Steel
Plasma is a fast, economical option for thicker 309S Stainless Steel plate where edge finish is less critical.
For estimating, a 100 × 100 × 10 mm block of 309S Stainless Steel weighs about 0.79 kg.

What is the typical lead time and minimum order for CNC Plasma Cutting 309S Stainless Steel?
CNC Plasma Cutting prototypes for 309S 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 Plasma Cutting 309S Stainless Steel?
Achievable tolerances for 309S 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 309S Stainless Steel parts to my drawing?
Yes. 309S 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 surface finish is achievable on 309S Stainless Steel with CNC Plasma Cutting?
Laser cutting leaves a clean cut face on 309S Stainless Steel with a small heat-affected zone; most parts need little secondary finishing.
