SUPER DUPLEX S32760 / F55 / 1.4501
Kev piav qhia
1.Muab lub zog siab dua li ob qho tib si austenitic thiab 22% Cr Duplex Stainless Steels UNS S32760 (F55) yog haum rau ntau yam kev siv hauv kev lag luam xws li Roj & Roj, CPI (Chemical Processing Industries), thiab Marine ib puag ncig.
UNS S32760 (F55 / 1.4501) tau teev nyob rau hauv NACE MR 01 75 rau kev pabcuam qaub thiab tau txais ASME Kev Pom Zoo rau Kev Siv Dej Hnyav.
Lub zog muaj zog los ntawm kev kho cua sov yooj yim rau Cov Txheej Txheem RH 950 thiab TH 1050. Lub zog tshwj xeeb tshaj plaws ntawm Cov Txheej Txheem CH 900 muaj ntau yam zoo uas txwv tsis pub muaj kev ua haujlwm thiab kev ua haujlwm tau tso cai. Hauv nws cov kev kho cua sov, cov hlau no muab cov khoom siv tshwj xeeb ntawm qhov kub txog li 900 ° F (482 ° C).
