VT machining offers CNC Reaming for 317L Stainless Steel (UNS S31703 / 1.4438), typically supplied annealed. More Mo than 316L for harsher chemical service.
CNC Reaming Notes for 317L Stainless Steel
317L Stainless Steel can rub and close up behind the reamer, so we leave a consistent stock allowance and keep the reamer cutting rather than burnishing.
For estimating, a 100 × 100 × 10 mm block of 317L Stainless Steel weighs about 0.80 kg.

Can VT machining make custom 317L Stainless Steel parts to my drawing?
Yes. 317L 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.
Why is 317L Stainless Steel a good choice for CNC Reaming?
317L Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC Reaming. We tune the process to the alloy so the finished 317L Stainless Steel machining part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Reaming 317L Stainless Steel?
Achievable tolerances for 317L 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.
What is the typical lead time and minimum order for CNC Reaming 317L Stainless Steel?
CNC Reaming prototypes for 317L 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 Reaming 317L Stainless Steel require dedicated tooling?
Most 317L Stainless Steel machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is CNC Reaming 317L Stainless Steel and how is it done?
CNC Reaming 317L Stainless Steel refers to reaming finishes drilled holes to a precise diameter and smooth surface in a single controlled pass. Applied to 317L 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.
