ASTM A789 ASME SA 789 SAF2507 UNS S32750 (EN 10216–5 1.4410) Stainless Steel is super duplex stainless steel with 25% kroom, 4% molübdeen, ja 7% Nikkel, mis on mõeldud nõudlikeks rakendusteks, mis nõuavad erakordset tugevust ja korrosioonikindlust, nagu keemiline protsess, naftakeemiline, ja mereveevarustus. Terasel on suurepärane vastupidavus kloriidipinge korrosioonipragunemisele, kõrge soojusjuhtivus, ja madala soojuspaisumise koefitsient.

Processing
Hot Forming
2507 should be hot worked between 1875 F and 2250 F. This should be followed by a solution anneal at 1925F minimum and a rapid air or water quench.
Cold Forming
Enamikku tavalistest roostevabast terasest moodustamismeetodeid saab kasutada külma töötamiseks 2507. Sulamil on suurem saagitugevus ja madalam elastsus kui austeniitilistel terastel, nii et valmistajad võivad leida, et kõrgemad moodustavad jõud, Suurenenud painutamise raadius, ja vajalik on suurenenud toetus kevadiseks. Sügav joonistamine, venitusvormimine, ja sarnaseid protsesse on keerulisem täita 2507 kui austeniitse roostevabast terasest. Moodustamisel nõuab rohkem kui 10% külm deformatsioon, Soovitatav on lahendus ja kustutamine.
Kuumtöötlus
2507 tuleks pärast kuuma või külma moodustumist lahendada ja kustutada. Solution annealing should be done at a minimum of 1925 F. Lõõmutamisele tuleks kohe järgneda kiire õhk või vee kustutamine. Maksimaalse korrosioonikindluse saamiseks, Kuumtöödeldud tooted tuleks marineerida ja loputada.
