Exceptional Resistance rau Reductive Acid Corrosion
Cov ntsiab lus siab molybdenum (26-30%) endows Hastelloy B nrog ze li zoo meej corrosion kuj hauv kev txo cov xov xwm xws li hydrochloric acid, dilute sulfuric acid, thiab phosphoric acid, deb tshaj li cov pa austenitic stainless hlau thiab feem ntau nickel-based alloys.
Zoo heev hydrochloric acid corrosion kuj
Ua kom muaj kev ruaj ntseg hauv hydrochloric acid thoob plaws tag nrho cov ntsiab lus hauv qab kub taw tes, tsis muaj kev nyiam rau pitting lossis intergranular corrosion. Nws kuj tiv thaiv tsis yog -oxidizing acids xws li hydrogen chloride gas, formic acid, thiab acetic acid.
Zoo intergranular corrosion kuj
Tsim los nrog cov pa roj carbon tsawg (tsawg dua lossis sib npaug li 0.01%) thiab cov silicon tsawg (tsawg dua lossis sib npaug li 0.08%), txo qhov kev pheej hmoo ntawm carbide thiab silicide nag lossis daus hauv qhov vuam kub- thaj tsam cuam tshuam. Nws tuaj yeem siv nyob rau hauv feem ntau corrosive ib puag ncig nyob rau hauv raws li -welded mob yam tsis muaj post-weld kho cua sov.
Nruab nrab sulfuric thiab phosphoric acid corrosion kuj
Ua tau zoo nyob rau hauv sulfuric thiab phosphoric acids nyob rau hauv nruab nrab concentrations los yog qis dua, tshwj xeeb tshaj yog haum rau non{0}}oxidizing acidic tov uas muaj chlorides los yog fluorides.
Zoo formability thiab weldability
tuaj yeem tsim kub lossis txias siv cov txheej txheem sib xyaw, nrog kev sib txuas zoo (GTAW, GMAW, SMAW). Nws raug nquahu kom siv qhov sib txuam Hastelloy B vuam hlau. Oxidizing atmospheres (xws li nitric acid lossis oxygen- muaj cov ntsiab lus) yuav tsum tau zam, vim tias lawv yuav ua rau muaj kev txhim kho corrosion ntau.

High -kev ua haujlwm kub
Hastelloy B tsis pom zoo siv rau hauv cov huab cua oxidizing (xws li nitric acid, oxygen- muaj cov kev daws teeb meem), vim tias nws yuav oxidize sai thiab ua tsis taus nyob rau hauv siab - kub oxidizing ib puag ncig. Nws lub hom phiaj daim ntawv thov yog nyob rau hauv kev txo cov kua qaub tawm, nrog rau kev pom zoo siab tshaj plaws kev pab cuam kub ntawm tsawg tshaj li los yog sib npaug rau 450 degree.
Pitting Resistance Equivalent (PREN): Tsis siv tau (PREN cov mis laij lej feem ntau yog siv rau chromium-cov hlau tsis muaj steels; Hastelloy B muaj cov ntsiab lus chromium tsawg heev thiab tsis vam khom rau qhov sib npaug ntawm qhov kev ntsuas). Txawm li cas los xij, kev xeb tsis sib xws yuav tshwm sim nyob rau hauv lub xub ntiag ntawm oxidizing impurities.Applicable Media: Hydrochloric acid (tag nrho cov concentrations, hauv qab boiling point) Dilute sulfuric acid (tsawg dua los yog sib npaug li 60%, tshwj xeeb tshaj yog thaum muaj chloride ions)
