VT machining offers CNC Turning for 2507 Duplex Stainless Steel (UNS S32750 / 1.4410), typically supplied solution annealed. Super-duplex with PREN >40; harder to machine than 2205.
CNC Turning Notes for 2507 Duplex Stainless Steel
On the lathe 2507 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 2507 Duplex Stainless Steel weighs about 0.78 kg.
