1.Ho fana ka matla a phahameng ho feta ka bobeli austenitic le 22% Cr Duplex Stainless Steels UNS S32760 (F55) e loketse mefuta e fapaneng ea likopo liindastering tse kang Oli & Gas, CPI(Chemical Processing Industries), le tikoloho ea Marine.
UNS S32760 (F55 / 1.4501) e thathamisitsoe ho NACE MR 01 75 bakeng sa ts'ebeletso e bolila 'me e fumane tumello ea ASME bakeng sa lits'ebetso tsa Pressure Vessel.
maemo a matla ka liphekolo tse bonolo tsa mocheso ho Maemo a RH 950 le TH 1050. Matla a phahameng a ikhethang a Condition CH 900 a fana ka melemo e mengata moo ductility e fokolang le ho sebetsa ho lumelloang. Boemong ba eona ba kalafo ea mocheso, motsoako ona o fana ka thepa e ikhethang ea mochini mochesong o fihlang ho 900 ° F (482 ° C).
