1.4410 super duplexstainless hlau, tseem hu ua UNS S32750 thiab SAF 2507, yog cov hlau uas muaj corrosion-resistant heev uas zoo haum rau siv nyob rau hauv ib puag ncig hnyav. Qhov no1.4410 stainless hlauqib yog super duplex stainless hlau nrog dual-theem microstructure uas sib txuas cov khoom ntawm ob qib austenitic thiab ferritic.
1.4410 Tshuaj muaj pes tsawg leeg: Chromium
Chromium yog lub ntsiab alloying hauv 1.4410 super duplex stainless hlau thiab pab txhawb rau nws qhov tshwj xeeb corrosion kuj. din 1.4410 duplex qib muaj nyob nruab nrab ntawm 24% thiab 26% chromium, uas yuav pab tiv thaiv kev tsim ntawm xeb thiab lwm yam corrosion.
Super Duplex 2507 Cov Khoom Siv: Molybdenum
Molybdenum yog lwm qhov tseem ceeb alloying nyob rau hauv 1.4410 super duplex stainless hlau thiab pab txhawb rau nws tiv thaiv corrosion nyob rau hauv ib puag ncig hnyav. Cov hlau tsis muaj steel 1.4410 muaj nyob nruab nrab ntawm 3% thiab 5% molybdenum, uas pab tiv thaiv kev xeb hauv zos thiab lwm yam kev tawm tsam.
UNS S32750 Tshuaj muaj pes tsawg leeg: Nitrogen
Nitrogen yog ntxiv rau duplex 1.4410 alloy 2507 los txhawb kev tsim cov theem austenitic hauv cov hlau lub microstructure. Qhov no yuav pab txhim kho lubwb 2507steel cov khoom siv kho tshuab thiab nws cov kev tiv thaiv corrosion.
A182 F53 Tshuaj muaj pes tsawg leeg: Nickel, tooj liab, thiab tungsten
Lwm cov ntsiab lus uas muaj nyob hauvSuper duplex UNS S32750 rajmuaj xws li nickel, tooj liab, thiab tungsten. Cov ntsiab lus no pab txhawb kev txhim kho ntxivA790 UNS S32750corrosion kuj thiab mechanical zog.
Hauv kev xaus, cov tshuaj muaj pes tsawg leeg ntawmS32750 super duplexyog ua tib zoo sib npaug los muab tshwj xeeb corrosion kuj thiab txhua yam khoom. Qhov noASME SA 240 UNS S32750 phajyog qhov zoo rau kev siv nyob rau hauv ib puag ncig hnyav uas lwm qib ntawm stainless hlau yuav ua tsis tiav. Nws ob-theem microstructure, qib siab ntawm cov ntsiab lus tseem ceeb alloying, thiab ua tib zoo sib xyaw ua ke tag nrho ua rau nws qhov kev ua tau zoo tshwj xeeb hauv ntau hom kev siv.
