Qhov tseem ceeb sib txawv hauv daim ntawv thov
Corrosion Resistance: Txo vs. Oxidizing
- B3 rau Txo Media:Yog tias koj qhov project cuam tshuam nrog qhov kub siab, lossis Phosphoric acid tsis muaj oxidizing impurities,B3 yog qhov kev xaiv zoo tshaj. Nws zam cov theem nkig feem ntau pom hauv B-series alloys ua ntej.
- C276 rau Mixed Media:Yog hais tias ib puag ncig hloov pauv ntawm kev txo qis thiab oxidizing, los yog muaj "qhuav" acids nrog ferric lossis cupric ntsev,C276 yuav tsum. Nws cov ntsiab lus Chromium muab cov yeeb yaj kiab tiv thaiv uas B3 tsis muaj.
Thermal stability
Hastelloy B3muaj qhov zoo sib xws hauv kev tsim khoom. Nws tiv thaiv kev tsim ntawm cov nplej - ciam teb carbide precipitates nyob rau hauv lub vuam tshav kub- cuam tshuam cheeb tsam, ua rau nws muaj kev ruaj ntseg rau cov qauv kev ncaj ncees nyob rau hauv cov tshuaj ua cov hlab ntsha ntau tshaj cov laus nickel alloys.
Daim ntawv thov
Hastelloy B3 / UNS N10675 / DIN 2.4600feem ntau yog siv rau hauv kev lag luam tshuaj, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas muaj zog txo acids, xws li hydrochloric acid, nrog rau sulfuric acid thiab phosphoric acid ib puag ncig.
Alloy C-276, 2.4819,UNS N10276yog dav siv nyob rau hauv ntau yam industries, nrog rau cov tshuaj ua, pulp thiab ntawv ntau lawm, kev tswj cov pa phem, pov tseg kev kho mob, thiab marine daim ntaub ntawv, qhov twg corrosion kuj mus rau ib tug ntau yam ntawm ib puag ncig yuav tsum tau.

Cov lus nug nquag nug (FAQ)
Q1: Puas yog Hastelloy B3 kim dua C276?
Feem ntau, yog. Vim tias cov ntsiab lus ntawm Molybdenum siab dua thiab cov txheej txheem tsim tshwj xeeb los xyuas kom meej thermal stability, Hastelloy B3 feem ntau nqa cov nqi lag luam ntau dua ib kilogram dua li C276.
Q2: Kuv puas tuaj yeem txuas C276 thiab B3 ua ke?
Nws yog ua tau tab sis yuav tsum tau tshwj xeeb welding consumables (feem ntau Alloy C22 los yog zoo sib xws) thiab nruj ua raws li cov cua sov- cov txheej txheem tawm tswv yim. Nrog peb pab neeg ua haujlwm rau cov txheej txheem vuam tshwj xeeb.
Q3: Cov hlau twg zoo dua rau Flue Gas Desulfurization (FGD)?
Hastelloy C276yog tus qauv kev lag luam rau FGD systems vim nws muaj peev xwm los lis sulfur compounds thiab chloride-induced pitting ib txhij.
