Taw qhia ASTM A790 UNS S32760 Seamless thiab Welded yeeb nkab
ASTM A790 UNS S32760 Cov Lus Qhia Tshwj Xeebyog ib tug super duplex stainless hlau yeeb nkab uas nquag siv nyob rau hauv daim ntaub ntawv uas corrosion kuj yog ib qho tseem ceeb. Qhov no1.4501 Super DuplexCov khoom siv feem ntau yog siv rau hauv petrochemical, tshuaj, thiab roj thiab roj kev lag luam vim nws muaj kev tiv thaiv siab rau pitting, crevice corrosion, thiab kev ntxhov siab corrosion tawg. Ntxiv thiab,Super Duplex F55yog ib qho kev xaiv zoo heev rau siv nyob rau hauv siab - siab thiab siab - qhov kub thiab txias ib puag ncig vim nws muaj zog thiab toughness.

ASTM A790 Txheem Txheej Txheem:
- ASME SA790specification npog cov kev cai tsim rau duplex thiab superduplex stainless hlau yeeb nkab, nrog rau seamless thiab welded yeeb nkab.
- UNS S32760yog ib tug duplex stainless hlau qib nyob rau hauv tus qauv no, kuj hu uaZeron 100.
- Cov txheej txheem no hais txog cov kev xav tau ntawm cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev, kev ua haujlwm, kev sim, tshuaj xyuas, cim thiab ntim cov kav dej.
- Duplex stainless hlau yog ib qho tshwj xeeb alloy muaj xws li chromium, nickel, molybdenum thiab lwm yam khoom. Nws muaj lub zog siab thiab zoo corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv chlorine - muaj cov xov xwm.
Lub ntsiab nta ntawm ASTM A790 UNS S32760 Yeeb Nkab:

- Yield zog: Ntau dua los yog sib npaug rau 550 MPa (80 ksi)
- Elongation: Ntau dua lossis sib npaug li 25%
3. Super Duplex s32760 / F55 / 1.4501 Corrosion Resistance:
Kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj chlorine - muaj cov xov xwm.
Zoo heev hnav tsis kam thiab pitting corrosion kuj.
4. Weldability:
ASTM A790 UNS S32760 khoom muaj qhov zoo weldability, haum rau kev siv vuam xws li TIG (GTAW) thiab MIG (GMAW).
5. Kev kho cua sov:
1.4501 khoomyog Tsis muaj kev kho cua sov yuav tsum tau, feem ntau nkag rau hauv cov tshuaj annealed mob.
Qhov sib txawv ntawm Seamless thiab Welded kav:
1.4501 S32760 (F55) Super Duplex Seamless Yeeb Nkab:
- Lub seamless variant yog tsim los ntawm cov txheej txheem uas muaj kev tho ib qho khoom siv hlau thiab tom qab ntawd kos nws mus rau hauv lub raj hollow.
- Qhov zoo muaj xws li lub zog tensile ntau dua thiab tsis muaj welds, txo cov peev xwm rau corrosion.
- Haum rau kev kub siab, kev kub siab thiab kev siv tseem ceeb xws li kev lag luam roj thiab roj.
Super Duplex S32760 Welded Yeeb Nkab:
- Lub welded version yog tsim los ntawm fusing ob daim hlau ua ke los ntawm cov txheej txheem vuam los tsim ib lub raj txuas ntxiv.
- Haum rau kev siv dav dav, tus nqi qis, yooj yim los tswj kev tsim khoom.
- Hauv qee qhov xwm txheej, welds tuaj yeem ua cov ntsiab lus rhiab rau corrosion.
Thaum xaiv cov yeeb nkab seamless lossis welded, cov txheej txheem thov tshwj xeeb, cov nqi tsim nyog thiab cov kav dej yuav tsum tau txiav txim siab.ASME SA790 UNS S32760 yeeb nkab, txawm tias seamless lossis welded yeeb nkab, muab kev ua tau zoo tshaj plaws ntawm kev tiv thaiv corrosion thiab cov khoom siv kho tshuab, qhov kev xaiv nyob ntawm cov kev xav tau tshwj xeeb engineering.
