VT machining offers CNC Turning for 2205 Duplex Stainless Steel (UNS S32205 / 1.4462), typically supplied solution annealed. Roughly double the yield strength of 316 with better chloride stress-corrosion resistance.
CNC Turning Notes for 2205 Duplex Stainless Steel
On the lathe 2205 Duplex Stainless Steel needs chip-breaker inserts and constant chip load to avoid long, stringy swarf.
For estimating, a 100 × 100 × 10 mm block of 2205 Duplex Stainless Steel weighs about 0.78 kg.
