1. Dab tsi yog super duplex s32760 sib npaug rau?
European / Nordic Cov Qauv:
En 10216-5}: x2cnimon 25-7-4 (1.4501)
SS 2328 (Swedish txheem)
ISO txheem:
ISO 15510: x2cnimon 25-7-4
Lwm cov kev tsim tawm hauv cheeb tsam:
JIS SUS825 (Nyiv)
Afnor z2cnd 25-07 (Fabkis)
D tas w . nr . 1.4501 (lub teb chaws Yelemees)
Cov kev sib raug zoo no zoo ib yam li tshuaj lom neeg (24-26% ni, 3-5% mo, ~}}
2. Dab tsi yog lub hardness ntawm super duplex s32760?
Rockwell Hardness (HRB): Tsawg dua los yog sib npaug rau 31
Vickers Hardness (HV): Tsawg dua los yog sib npaug rau 320
Brinell Hardness (HB): Tsawg dua los yog sib npaug rau 310
Qhov kev ua haujlwm hardness no nrog cov muaj peev xwm, ua kom haum rau kev ua haujlwm tsis zoo (e} kub}
3. Dab tsi yog cov paib zog zog ntawm super duplex s32760?
Yam tsawg kawg nkaus los lub zog (RP0.2):
Nyob rau hauv chav tsev kub: ntau dua lossis sib npaug nrog 550 mpa (79,770 psi)
Ntawm 300℃(572℃f): ntau dua lossis sib npaug nrog 450 mpa (65,260 psi)
Lub zog tensile: Ntau dua los yog sib npaug rau 750 mpa (108,780 psi)
Elongation: Ntau dua los yog sib npaug rau 25%
Qhov no cov paib muaj zog tag nrho rau S32760 los tiv thaiv cov nra hnyav thiab cov roj ntsha (E} paheej}}
4. Dab tsi qib S32760 cov khoom siv yog dab tsi?
Tshuaj lom neeg cov tshuaj (cov ntsiab lus tseem ceeb):
Chromium (CR): 24-26%
Nickel (NI): 6.0-8.0%
Molybdenum (MO): 3.0-5.0%
Nitrogen (n): 0.20-0.30%
Tooj (CU): 0.5-1.0% (ntxiv rau kev ua kom zoo rau cov sulfuric acid)
Qauv Ua Haujlwm:
ASTM A890 / A890M (CASTINGS)
ASTM A240 / A240M (Wrought daim phiaj, ntawv txheeb)
UNR UNL UNRT S32760 (TEB CHAWS XA)
En 10088-3: x2cnimon 25-7-4 (Europe)
Nws "super duplex" qauv stems los ntawm surpassing tus qauv duplexs (e {}}} ...}
5. Dab tsi yog qhov txawv ntawm S32750 thiab S32760?
Thaum sib piv S32750 thiab S32760, ob leeg yog super duplex alloys, tab sis S32760 suav nrog lub ntsej muag ntshiab xws li sei2 9}} Microstructure {13. s32760 tus tooj liab liab ntxiv ua rau cov sulfuric, ua rau nws acidosion, e {}}, tshuaj lom neeg ua haujlwm lossis ntawv mills). Thaum S32750 yog qhov mus-rau rau offshore roj thiab desalination, S32760 tus qauv tooj liab ua rau nws muaj txiaj ntsig zoo tab sis tseem ceeb rau kev sib xyaw kua qaub-chloride.
