Kufotokozera:

S32750 (2507, F53, 1.4410) chitsulo chosapanga dzimbiri cha duplex chili ndi 25% chromium, 4% molybdenum ndi 7% faifi tambala.
Chitsulo cha S32750 chapawiri-gawo chili ndi mphamvu zolimba komanso kukana dzimbiri, zomwe zimagwiritsidwa ntchito kwambiri pokonza mankhwala, mafakitale a petrochemical ndi zida zam'madzi.
S32750 wapawiri gawo zitsulo ali kukana kwambiri chloride dzimbiri, mkulu matenthedwe madutsidwe ndi otsika matenthedwe kukulitsa coefficient.
Muli ndi chromium, molybdenum ndi nayitrojeni wambiri ndipo imalimbana ndi dzimbiri, crack corrosion ndi dzimbiri.
Chitsulo cha S32750 chapawiri-gawo chimakhalanso ndi mphamvu yayikulu ndipo sichiyenera kugwiritsidwa ntchito pa kutentha pamwamba pa 570 ° C, pomwe kulimba kwake kumachepa pakapita nthawi.
S32750 wapawiri gawo zitsulo Integrated zitsulo ferritic ndi austenitic zitsulo ndi katundu opindulitsa kwambiri, chifukwa zitsulo chromium ndi molybdenum zili ndi mkulu kwambiri, kotero ali kwambiri kukana dzimbiri, mpata dzimbiri ndi luso yunifolomu dzimbiri, duplex microstructure amaonetsetsa kuti chitsulo amatha kukana mkulu kupanikizika dzimbiri akulimbana, ndi mphamvu mawotchi ndi mkulu.

S32750 2507 F53 1.4410 Chemical yopangidwa ndi chitsulo chosapanga dzimbiri

S32750 (2507, F53, 1.4410) super duplex zitsulo zosapanga dzimbiri zakuthupi komanso zamakina:

1. S32750 (2507, F53, 1.4410) kachulukidwe kachitsulo kagawo kawiri: 8.0g/cm3.
2. Kulimba kwamphamvu kwa S32750 (2507, F53, 1.4410) duplex chitsulo mphamvu yowonjezera: σb≥800Mpa.
S32750 (2507, F53, 1.4410) magawo awiri zitsulo zokolola mphamvu: σ0.2≥550Mpa
4, S32750 (2507, F53, 1.4410) elongation yazitsulo ziwiri: δ≥15%.
5. S32750 (2507, F53, 1.4410) kuuma kwazitsulo ziwiri (HB): 310

S32750 (2507, F53, 1.4410) super duplex zosapanga dzimbiri kukana dzimbiri:

2507 chitsulo chosapanga dzimbiri chophimbidwa ndi mankhwala

1. Poyerekeza ndi 904L, S32750 chitsulo chapawiri-gawo chili ndi dzimbiri kukana kuchepetsa sulfuric acid wothira chloride ayoni.
904L ndi alloy austenitic alloy opangidwa mwapadera kuti asawonongeke ndi sulfuric acid yoyera.
Kuchulukira kwa chromium ndi molybdenum mu S32750 dual-phase chitsulo kumapangitsa kuti zisawonongeke ndi dzimbiri zonse za organic acid monga asidi ndi acetic acid.
Chitsulo cha S32750 duplex chilinso ndi kukana kwa dzimbiri kolimba ku ma inorganic acid, makamaka omwe ali ndi ma chloride.
Gulu la 316L silingagwiritsidwe ntchito m'malo okhala ndi hydrochloric acid komwe kumatha kuwononga dzimbiri m'deralo kapena padziko lonse lapansi.
S32750 wapawiri gawo zitsulo angagwiritsidwe ntchito kuchepetsedwa hydrochloric acid chilengedwe, ndi kukana amphamvu kuwonongeka malo ndi mng'alu dzimbiri luso.
2. Intercrystalline corrosion S32750 dual-phase iron imakhala ndi mpweya wochepa kwambiri, womwe umachepetsa kwambiri chiopsezo cha mpweya wa intercrystalline carbide panthawi ya kutentha.Chifukwa chake, alloy iyi imalimbana kwambiri ndi dzimbiri zokhudzana ndi mpweya wa intercrystalline.
3. Stress corrosion cracking: chifukwa cha kuchuluka kwake kwa alloy, kukana kwa dzimbiri ndi mphamvu ya S32750 zitsulo ziwiri-gawo ndi bwino kuposa 2205.
S32750 wapawiri - gawo lachitsulo chopangidwa ndi chitsulo chimapangitsa kuti chisavutike kwambiri ndi kupsinjika kwa kuwonongeka kwa dzimbiri.
4, dzimbiri ndi dzimbiri: pali njira zambiri zoyezera kukana kwa dzimbiri zazitsulo mu njira yokhala ndi chloride.Kutentha koopsa kwa dzimbiri ndi kuwonongeka kwa chitsulo chosapanga dzimbiri chosapanga dzimbiri pa 1M sodium chloride solution chafotokozedwa.
Zotsatira zosiyanasiyana zoyesera zikuwonetsa kuti S32750 yapawiri - gawo lachitsulo lili ndi kukana kwa dzimbiri.
5, crack corrosion: ming'alu ya nyumbayo ndi zina zimakhala zosapeŵeka, zomwe zimapangitsa kuti zitsulo zosapanga dzimbiri zikhale zosavuta kuwononga chilengedwe cha chloride.

2507 chitsulo chosapanga dzimbiri chophimbidwa ndi mankhwala
