VT machining offers CNC Swiss Machining for 1020 Steel (UNS G10200 / C22 / S20C), typically supplied hot-rolled or cold-drawn. Close to 1018 with slightly lower Mn; general machined parts.
CNC Swiss Machining Notes for 1020 Steel
1020 Steel is well suited to Swiss-type turning for small, long parts in volume, with short cycle times from bar.
For estimating, a 100 × 100 × 10 mm block of 1020 Steel weighs about 0.79 kg.

What surface finish is achievable on 1020 Steel with CNC Swiss Machining?
Surface finish on 1020 Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What tolerances can you hold for CNC Swiss Machining 1020 Steel?
Achievable tolerances for 1020 Steel turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
What material thickness or size range suits CNC Swiss Machining 1020 Steel?
Turned 1020 Steel parts are produced from bar or chuck stock across a wide diameter range.
Does CNC Swiss Machining 1020 Steel require dedicated tooling?
Most 1020 Steel turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
