Khoom Description
ASTM A789 UNS S32750 Duplex Stainless Hlau Tube
Qhov zoo ntawm ASTM A789 UNS S32750 Duplex Stainless Tube
- Txhim kho Weldability: Ib qho ntawm S32750 qhov zoo tshaj plaws ntawm lwm cov ntaub ntawv yog nws cov weldability. Vim nws cov ntsiab lus tswj cov pa roj carbon monoxide thiab cov ntsiab lus alloying, nws muaj kev pheej hmoo tsawg ntawm hydrogen embrittlement thiab weld cracking piv rau lwm cov super-duplex stainless hlau.
- Oxidation Resistance: S32750 tuav nws cov oxidation tsis kam ntawm qhov kub thiab txias, kom cov khoom tsis degrade los yog poob kev ncaj ncees thaum raug kub. Qhov no ua rau nws tsim nyog rau kev siv xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob.
- Tus nqi -Kev ua tau zoo: Thaum S32750 muaj tus nqi pib dua piv rau tus qauv 304 lossis 316 stainless hlau, nws cov corrosion kuj zoo heev thiab lub zog txo kev txij nkawm thiab ncua kev pab cuam lub neej, ua rau nws raug nqi ntau dua - siv tau ntev.

Cov qhab nia xaiv tau
- UNS S31803 (2205): Lwm qhov dav siv duplex stainless hlau qib nrog zoo corrosion kuj thiab lub zog, tab sis nrog cov ntsiab lus qis qis dua cov qib superduplex.
- UNS S32760 (superduplex): Zoo ib yam li S32750, tab sis nrog me ntsis siab dua corrosion kuj nyob rau hauv corrosive ib puag ncig.
- UNS S32205: Tus nqi qis - lwm tus nqi rau S32750 nrog kev tiv thaiv corrosion zoo rau cov cheeb tsam qis dua.
- 904L: High- alloy austenitic stainless hlau uas tuaj yeem siv los ua lwm txoj hauv kev uas yuav tsum tau muaj kev tiv thaiv corrosion siab, txawm hais tias nws tsis muaj zog li duplex steel.
