SUPER DUPLEX S32760 / F55 / 1.4501
SHARAXA
1.Bixinta awoodo ka sarreeya labada austenitic iyo 22% Cr Duplex Stainless Steels UNS S32760 (F55) waxay ku habboon tahay codsiyada kala duwan ee warshadaha sida Saliidda & Gaaska, CPI (Warshadoyinka Kiimikada), iyo deegaanka badda.
UNS S32760 (F55 / 1.4501) waxay ku taxan tahay NACE MR 01 75 adeega dhanaan iyo kasbashada ASME Oggolaanshaha codsiyada cadaadiska Vessel.
Heerarka xoogga daawaynta kulaylka fudud ee Shuruudaha RH 950 iyo TH 1050. Awoodda aadka u sarreeya ee Xaaladda CH 900 waxay bixisaa faa'iidooyin badan halka ductility xaddidan iyo karti-shaqsiyeedka la oggol yahay.Xaaladda kulaylka lagu daweeyay, daawayntani waxay ku siinaysaa sifooyin farsamo oo gaar ah heerkulka ilaa 900 °F (482 °C).
