Hastelloy C-4
Kev Piav Qhia Luv:
Hastelloy C-4 (UNS NO6455)
Hastelloy C-4 Cov Nta thiab Daim Ntawv Thov Txheej Txheem Cej Luam:
Cov hlau no yog ib qho austenitic qis-carbon nickel-molybdenum-chromium alloy. Qhov sib txawv tseem ceeb ntawm Nicrofer 6616 hMo thiab lwm cov hlau uas muaj cov tshuaj zoo sib xws uas tau tsim ua ntej yog cov pa roj carbon tsawg, silicon, hlau thiab tungsten. Cov tshuaj no muaj kev ruaj khov zoo heev ntawm 650-1040 ° C thiab txhim kho kev tiv thaiv rau intergranular corrosion, zam kev cuam tshuam ntawm ntug kab corrosion thiab weld HAZ corrosion nyob rau hauv cov xwm txheej tsim nyog. Cov hlau siv rau hauv cov roj flue desulfurization systems, pickling thiab acid regeneration cog, acetic acid thiab cov tshuaj ua liaj ua teb, titanium dioxide ntau lawm (chloride txoj kev), electrolytic plating.

Kev ua tau zoo thiab cov kev cai ntawm Hastelloy C-4:
1, Thaum lub sijhawm kho cua sov, tsis txhob kov cov hlau sulfur, phosphorus, txhuas thiab lwm yam hlau uas yaj qis, yog tsis li ntawd cov hlau yuav tawg yooj yim, yuav tsum tau ceev faj tshem cov xim cim, xim qhia kub, xim pleev xim, roj nplua nyeem, roj thiab lwm yam av qias neeg. Yog cov roj muaj sulfur tsawg dua, cov roj av yuav tsum muaj sulfur tsawg dua 0.1%, cov roj hnyav yuav tsum muaj sulfur tsawg dua 0.5%. Kev siv hluav taws xob rau cua sov yog qhov kev xaiv zoo dua, vim tias lub tshuab hluav taws xob tuaj yeem tswj qhov kub thiab txias thiab cov roj hauv lub tshuab hluav taws xob huv. Yog tias cov roj hauv lub tshuab hluav taws xob huv txaus, koj tuaj yeem xaiv.
2, qhov kub thiab txias ntawm cov hlau ua los ntawm cov hlau sib xyaw ua ke yog 1080 ℃ ~ 900 ℃, thiab siv dej txias los yog lwm yam txias sai. Yuav kom tiv taus xeb zoo tshaj plaws, yuav tsum siv cua sov kho tom qab siv tshuaj kub kho.
