SUPER DUPLEX S32760 / F55 / 1.4501
DESCRIPTION
1.Kupereka mphamvu zapamwamba kuposa zonse za austenitic ndi 22% Cr Duplex Stainless Steels UNS S32760 (F55) ndizoyenera kugwiritsa ntchito zosiyanasiyana m'mafakitale monga Mafuta & Gasi, CPI(Chemical Processing Industries), ndi malo a Marine.
UNS S32760 (F55 / 1.4501) yalembedwa mu NACE MR 01 75 chifukwa cha ntchito zowawasa komanso kulandira Chivomerezo cha ASME pakugwiritsa ntchito Pressure Vessel.
milingo yamphamvu ndi njira zosavuta zochiritsira zotentha ku Zinthu RH 950 ndi TH 1050. Mphamvu yapamwamba kwambiri ya Condition CH 900 imapereka zabwino zambiri pomwe ductility ndi magwiridwe antchito amaloledwa.Munyengo yake yochizira kutentha, aloyiyi imapereka zida zapadera pamatenthedwe mpaka 900 ° F (482 ° C).
