Thaum tshav kub kub-resistant hlau 321
321 stainless hlau (uns unranium-stabilized Austenitic corrosion thiab txhawb nqa cov khoom siv hluav taws xob muaj zog ntawm 9,
Sab saum toj cov lus qhia
321 Stainless hlau (Unren S32100) yog titanium-stability {}} kev pab kub thiab siv tshuaj lom neeg surpassing 304 series, nws yog qhov kev xaiv zoo rau kev mob siab corrosive mob {}}}} [cov khoom ntiag tug)
Tub Ntxhais Nta & Qhov Zoo
Kev kub siab ruaj khov
- Nrog rau 900℃(sib quas ntus) thiab 925℃(ti colbide daus, tshwj xeeb yog nyob rau hauv {{5} Taug kev ib cheeb tsam.
{{0- 321 h variant txhim kho cov ntsiab lus ntawm cov ntsiab lus carbon ntau (tsawg dua lossis sib npaug rau cov boilers thiab cua sov sib pauv.
Corrosion Kuj
- ntais ntawv 304 hauv annealed lub xeev tab sis zoo nyob rau hauv chloride thiab acidic media ntawm nce kub .
- zam rau 200mg / l Chlorides hauv cov dej haus (20 degree), txo qis rau 150mg / l ntawm 60℃{5}.
Machining & Vuam
- Kev muaj kev muaj txiaj ntsig zoo tsis muaj postte-weld annealing, tab sis tsawg policability .
- Vuam ntawv: Yuav tsum 347 / 347Si Sau Ua Mov Vim Txog rau Titanium's Arc Hloov Chaw Txwv {}}
