VT machining offers CNC Plasma Cutting for 309 Stainless Steel (UNS S30900 / 1.4828), typically supplied annealed. Higher Cr/Ni for oxidation resistance to ~1000 °C.
CNC Plasma Cutting Notes for 309 Stainless Steel
Plasma is a fast, economical option for thicker 309 Stainless Steel plate where edge finish is less critical.
For estimating, a 100 × 100 × 10 mm block of 309 Stainless Steel weighs about 0.79 kg.

Request a QuoteFrequently Asked Questions
Can VT machining make custom 309 Stainless Steel parts to my drawing?
Yes. 309 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 the typical lead time and minimum order for CNC Plasma Cutting 309 Stainless Steel?
CNC Plasma Cutting prototypes for 309 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 material thickness or size range suits CNC Plasma Cutting 309 Stainless Steel?
Laser-cut 309 Stainless Steel thickness depends on the alloy and its reflectivity; we tune the fiber source and assist gas accordingly.
What surface finish is achievable on 309 Stainless Steel with CNC Plasma Cutting?
Laser cutting leaves a clean cut face on 309 Stainless Steel with a small heat-affected zone; most parts need little secondary finishing.
How clean are the edges produced by CNC Plasma Cutting on 309 Stainless Steel?
Laser cutting leaves 309 Stainless Steel with a narrow kerf and a clean, near burr-free edge and only a small heat-affected zone.
Does CNC Plasma Cutting 309 Stainless Steel require dedicated tooling?
Most 309 Stainless Steel cutting work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
