Hastelloy C276 kev kho cua sov thiab kev tsim khoom, C276 thiab txheej txheem cladding
Hastelloy C276 Txheej txheem cej luam:
Hastelloy C-276 alloy yog tungsten-muaj nickel-chromium-molybdenum alloy nrog cov ntsiab lus tsis tshua muaj silicon-carbon thiab suav tias yog cov khoom siv tiv thaiv corrosion-resistant universal. Feem ntau resistant rau cov chlorine ntub dej, ntau yam oxidizing chlorides, chloride ntsev daws, sulfuric acid thiab oxidizing ntsev, thiab muaj corrosion kuj zoo nyob rau hauv qis thiab nruab nrab kub hydrochloric acid. Yog li ntawd, nyob rau hauv peb caug xyoo dhau los, nws tau dav siv nyob rau hauv hnyav corrosive ib puag ncig, xws li tshuaj lom neeg kev lag luam, petrochemical kev lag luam, flue gas desulfurization, pulp thiab ntawv ua, kev tiv thaiv ib puag ncig thiab lwm yam kev lag luam teb.
Hastelloy C276 kev kho cua sov thiab kev tsim khoom:
thermoforming
Hastelloy C-276 alloy yog kub tsim thiab yuav tsum tau annealed tam sim ntawd ntawm 950 mus rau 1200 degree thiab tom qab ntawd txias sai sai hauv dej los yog huab cua. Nws raug nquahu kom ua kev kho cua sov tom qab ua haujlwm kub. Thaum cua sov, lub alloy yuav tsum tau muab tso rau hauv ib lub qhov cub uas tau muab tso rau hauv qhov cub rau lub hom phiaj tus nqi.
txias tsim
Lub alloy yuav tsum nyob rau hauv lub annealed mob kom pab tau txias ua hauj lwm. C-276 muaj zog txias ntau dua piv rau austenitic stainless hlau. Lub formability yog zoo dua li uas siv dav siv austenitic stainless hlau. Tsis tas li ntawd, cov khoom siv no ua haujlwm hnyav sai dua li cov hlau tsis zoo tib yam, yog li cov txheej txheem nruab nrab ntawm cov txheej txheem annealing yuav tsum tau ua thaum lub caij txias txias.
Descaling thiab pickling
C-276's oxides thiab discoloration nyob ze welds yog nplaum ntau dua stainless hlau. Nws raug nquahu kom siv txoj siv tawv zoo heev los yog disc rau kev sib tsoo. Yuav tsum tau saib xyuas kom tsis txhob muaj xim daj. Ua ntej pickling nyob rau hauv ib tug sib tov ntawm saltpeter thiab hydrofluoric acid, oxide txheej yuav tsum tau tawg thiab hauv av los ntawm sandblasting los yog zoo sib tsoo, los yog kho nyob rau hauv ib tug molten ntsev da dej. Cov txheej txheem corrosion ntawm lub tank pickling siv yuav tsum tau ua tib zoo saib xyuas, tshwj xeeb tshaj yog concentration thiab kub.
Tshuab dhos
C-276 yuav tsum tau machined nyob rau hauv kev kho cua sov. Txij li cov nyiam ua hauj lwm hardening yog ho nce piv rau austenitic stainless steels, lub cuab tam yuav tsum yeej ib txwm koom nyob rau hauv qis txiav speeds thaum pub tus nqi tsis siab dhau. Txiav hauv qab ntawm thaj tsam uas tau tsim los ntawm kev sib zog-hardened siv qhov tsim nyog txiav qhov tob. Los ntawm kev siv cov khoom siv hluav taws xob ntau los ua kom tau txais qhov zoo tshaj plaws ntawm cov cua kub dissipation, qhov zoo tshaj plaws dej-raws li lubricant rau cov txheej txheem machining muaj kev cuam tshuam loj heev rau cov txheej txheem machining ruaj khov.
Hastelloy C-276 daim ntawv thov thaj chaw:
Kev lag luam ntawv thiab pulp, piv txwv li rau kev zom zaub mov thiab bleaching tanks
Scrubbers, agitators thiab ntub ventilators hauv flue gas desulfurization systems
Cov khoom siv roj qaub qaub thiab cov khoom siv
Acetic acid ntau lawm reactor
Sulfuric acid txias
Kev tsim khoom thiab kev ua cov kab mob phosphoric acid
Cov twj tso kua mis, tshuaj fluorine, thiab lwm yam.
Hastelloy C276 corrosion kuj:
① Nyob rau hauv ob qho tib si oxidizing thiab txo cov huab cua, nws muaj corrosion kuj zoo heev rau feem ntau corrosive xov xwm.
② Kev tiv thaiv zoo heev rau pitting corrosion, crevice corrosion thiab kev nyuaj siab corrosion. Qhov siab dua Mo thiab Cr cov ntsiab lus ua rau cov hlau resistant rau chloride ion corrosion, thiab W lub ntsiab ntxiv txhim kho corrosion kuj. Tib lub sijhawm, Hastelloy C-276 alloy yog ib qho ntawm cov khoom siv tiv thaiv corrosion los ntawm cov tshuaj chlorine moist, hypochlorite thiab chlorine dioxide daws, thiab tiv taus cov tshuaj chloride siab xws li ferric chloride thiab tooj liab chloride. Zoo heev corrosion kuj. Nws yog tsim rau sulfuric acid daws ntawm ntau yam concentrations thiab yog ib qho ntawm ob peb cov ntaub ntawv uas yuav siv tau nyob rau hauv kub concentrated sulfuric acid daws.
Hastelloy C276 thiab laser cladding tshuab:
Hastelloy C276 yog Ni-Mo-Cr-W series npib tsib xee-raws li alloy nrog siab zog, toughness thiab corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv xov xwm xws li ntub chlorine thiab chloride ntsev tov. Yog li ntawd, cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau tshawb fawb txog kev npaj C276 txheej. Supersonic nplaim taws txau tshuab yog siv los npaj C276 cladding txheej ntawm 316L stainless hlau. Lub cladding txheej muaj txheej txheej txheej thiab yog ntom. Nws microhardness thiab hnav tsis kam yog siab dua li cov khoom siv hauv paus. C276 txheej yog laser cladded ntawm rab phom phom hlau. Cov txheej yog tsim tau zoo thiab cov kev tiv thaiv corrosion nyob rau tib theem li cov chromium plating txheej.
Kev tshawb fawb qhia tau hais tias C276 txheej muaj kev sib raug zoo nrog cov hlau thiab tuaj yeem txhim kho qhov hnav tsis kam thiab corrosion kuj ntawm steel nto. Tam sim no, C276 Hastelloy coatings npaj los ntawm domestic thiab txawv teb chaws counterparts feem ntau yog siv rau hlau.
