Txheej txheem cej luam ntawm 2205 Duplex Stainless Steel
Duplex 2205 stainless hlau (ob qho tib si ferritic thiab austenitic) yog siv dav hauv cov ntawv thov uas xav tau kev tiv thaiv corrosion zoo thiab lub zog. Cov hlau stainless hlau qib S31803 tau dhau los ntawm ntau qhov kev hloov kho ua rau UNS S32205. Qib no muaj kev tiv thaiv corrosion ntau dua.
Thaum kub tshaj 300 ° C, cov khoom me me ntawm qib no yuav los nag, thiab thaum kub qis dua -50 ° C cov khoom me me yuav hloov pauv mus rau qhov tawg yooj yim; yog li ntawd, qib no ntawm cov hlau tsis xeb tsis haum rau kev siv ntawm cov kub no.

Qhov Zoo ntawm Duplex Stainless Steel
l Lub zog zoo dua
Ntau qib duplex muaj zog txog li ob npaug ntawm cov qib austenitic thiab ferritic stainless hlau.
l Kev Muaj Zog Siab thiab Kev Ua Tau Zoo
Cov hlau tsis xeb duplex feem ntau yooj yim tsim dua thaum muaj kev nyuaj siab dua li cov qib ferritic thiab muab kev tawv dua. Txawm hais tias lawv feem ntau muab cov nqi qis dua li cov hlau austenitic, cov qauv tshwj xeeb thiab cov yam ntxwv ntawm cov hlau duplex feem ntau ntau dua li qhov kev txhawj xeeb.
l Kev Tiv Thaiv Kev Kub Siab
Nyob ntawm qib uas nug txog, cov hlau tsis xeb duplex muaj kev tiv thaiv xeb zoo sib xws (lossis zoo dua) zoo li cov qib austenitic. Rau cov hlau alloys uas muaj nitrogen, molybdenum, thiab chromium ntau ntxiv, cov hlau ua rau muaj kev tiv thaiv zoo rau ob qho tib si corrosion crevice thiab chloride pitting.
Kev Siv Nyiaj Zoo
Duplex stainless hlau muaj tag nrho cov txiaj ntsig saum toj no thaum xav tau cov molybdenum thiab nickel qis dua. Qhov no txhais tau tias nws yog qhov kev xaiv pheej yig dua li ntau hom austenitic ib txwm muaj ntawm cov hlau stainless. Tus nqi ntawm duplex alloys feem ntau tsis tshua muaj kev hloov pauv ntau dua li lwm cov hlau ua rau nws yooj yim dua los kwv yees tus nqi - ob qho tib si ntawm qib pib thiab lub neej tas mus li. Lub zog siab dua thiab kev tiv thaiv corrosion kuj txhais tau tias ntau qhov chaw ua los ntawm kev siv duplex stainless tuaj yeem nyias dua li lawv cov austenitic counterparts muab tus nqi qis dua.
