VT machining offers CNC Turning for 310 Stainless Steel (UNS S31000 / 1.4841), typically supplied annealed. Highest-heat standard austenitic (~1100 °C); very gummy, low speeds required.
CNC Turning Notes for 310 Stainless Steel
On the lathe 310 Stainless Steel needs chip-breaker inserts and constant chip load to avoid long, stringy swarf.
For estimating, a 100 × 100 × 10 mm block of 310 Stainless Steel weighs about 0.79 kg.

What is CNC Turning 310 Stainless Steel and how is it done?
CNC Turning 310 Stainless Steel refers to cNC turning rotates the workpiece against a single-point tool to produce cylindrical features, threads and grooves. Applied to 310 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.
What surface finish is achievable on 310 Stainless Steel with CNC Turning?
Surface finish on 310 Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What material thickness or size range suits CNC Turning 310 Stainless Steel?
Turned 310 Stainless Steel parts are produced from bar or chuck stock across a wide diameter range.
Why is 310 Stainless Steel a good choice for CNC Turning?
310 Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC Turning. We tune the process to the alloy so the finished 310 Stainless Steel turning part meets your dimensional and functional requirements.
Does CNC Turning 310 Stainless Steel require dedicated tooling?
Most 310 Stainless Steel turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Can VT machining make custom 310 Stainless Steel parts to my drawing?
Yes. 310 Stainless Steel turning 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.
