Hastelloy C276 yog dab tsi, thiab cov khoom zoo li cas tuaj yeem ua rau C276 alloy zoo?
C-276
Hastelloy C-276
Hastelloy C-276 alloy yog tungsten-muaj nickel-chromium-molybdenum alloy nrog cov ntsiab lus tsis tshua muaj silicon-carbon thiab suav tias yog qhov zoo tshaj plaws corrosion-resistant alloy. 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.
Suav lub npe Hastelloy C-276 Tensile zog σb Ntau dua lossis sib npaug rau 730Mpa Elongation δ Ntau dua lossis sib npaug li 40% Hardness HRB Tsawg dua lossis sib npaug rau 100
Corrosion kuj
Cov alloy no muaj cov khoom nram qab no:
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.
Mechanical cwj pwm
Lub zog tensile: σb Ntau dua lossis sib npaug ntawm 730Mpa, elongation: δ Ntau dua lossis sib npaug li 40%, hardness: HRB Tsawg dua lossis sib npaug rau 100.
Kub sib sau ntawm Hastelloy C{0}} alloy yog tam sim ntawd annealed ntawm 1150 degree thiab quenched nrog dej. Txias deformation ntawm Hastelloy C-276 alloy yuav ua kom nws lub zog.
Hastelloy C-276 alloy muaj qhov zoo sib xws rau cov hlau tsis zoo austenitic. Txawm li cas los xij, vim tias nws muaj zog dua li qub austenitic stainless hlau, yuav muaj kev ntxhov siab ntau dua thaum lub caij txias. 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.
Lub cev muaj zog
Lub cev muaj zog ntawm Hastelloy C-276 alloy yog raws li nram no:
Cov khoom muaj pes tsawg leeg: 57Ni-16Cr-16Mo-5Fe-4W-2.5Co*-1Mn*-0.35V *-0.08Si*-0.01C* * yog cov npoo loj
Cov qauv kev coj ua: UNS N10276, ASTM B575, ASME SB575, DIN / EN 2.4819
