Alloy 31 Phaj daim ntawv thov hauv kev lag luam tshuaj
N08031 phaj hauv Concentrated sulfuric acid cia thiab kev thauj mus los
Nyob rau hauv thaj tsam ntawm 90%-98% concentrated sulfuric acid cia, Alloy 31 daim hlau cia siab rau lawv cov cim Cr-Ni-Mo-N alloy system los ua ib tug tuab Cr₂O₃ passivation zaj duab xis, uas zoo tiv thaiv lub zog oxidative corrosion ntawm concentrated sulfuric acid.
alloy N08031 phaj nyob rau hauv Reaction extraction tank thiab pom system
Cov tub ntxhais corrosion cheeb tsam ntawm ntub dej phosphoric acid ntau lawm (30% H₃PO₄+5% HF+20% khoom impurities + 80℃) yuav tsum tau "kev hnav tsis kam" rau cov ntaub ntawv. Tus nqi PREN (pitting kuj sib npaug) ntawm Alloy 31 phaj yog siab li 48, ua kom ruaj khov AlN-Fe₂Ni passivation txheej hauv F⁻- muaj cov xov xwm.
31 alloy nyob rau hauv Phosphoric acid evaporator thiab concentration system
Hauv seem phosphoric acid concentration (45% H₃PO₄+ kab Cl⁻+120℃+ lub tshuab nqus tsev ib puag ncig), Alloy 31 phaj muaj kev tiv thaiv zoo heev rau crevice corrosion. Nws cov nplaim roughness tuaj yeem tswj tau ntawm Ra Tsawg dua lossis sib npaug ntawm 0.8μm, thiab cov vuam zoo tsim los ntawm cov txheej txheem laser vuam ua rau txo qis qhov kev pheej hmoo ntawm crevice corrosion tshwm sim los ntawm scale deposition.
nickel alloy 31 phaj hauv Hydrochloric acid distillation thiab refining ntaus ntawv
Raws li kev ua haujlwm ntawm 15% -20% hydrochloric acid + 50 degree, qhov tsis zoo corrosion kuj ntawm Alloy 31 phaj zoo dua li cov pa nickel-based alloys. Nws daim ntawv thov nyob rau hauv kev txhawb nqa qauv ntawm bubbling ntauwd packing tsub kom lub neej ntawm cov cuab yeej los ntawm 18 lub hlis ntawm Hastelloy B3 alloy mus rau ntau tshaj 5 xyoo.
Nickel alloy n08031 phaj Mixed acid tshuaj tiv thaiv kab mob
Nyob rau hauv cov tub ntxhais reactor ntawm lithium roj teeb electrolyte ntau lawm (ua hauj lwm mob: 10% H₂SO₄+15% HF+60 degree), Alloy 31 phaj qhia tshwj xeeb zoo. Cov nyhuv synergistic ntawm nws cov ntsiab lus Cr (27%) thiab N cov ntsiab lus (0.22%) tsim ib txheej ruaj khov CrF3 passivation txheej hauv HF nruab nrab, thiab Ni-raws li cov khoom siv tau zoo tiv thaiv oxidative corrosion ntawm sulfuric acid.
Alloy 31 Khoom siv tau zoo
npib tsib xee alloy 31 strip Processing technology optimization thiab vuam tshuab
Alloy 31 phaj muaj kev ua haujlwm txias txias zoo thiab tuaj yeem tiv taus qhov siab tshaj ntawm 30% txias deformation yam tsis muaj kev cuam tshuam corrosion. Cov txheej txheem vuam siv ERNiCrMo-13 vuam hlau (sib piv cov phaj muaj pes tsawg leeg) thiab TIG pulse vuam tshuab. Cov ntsiab lus ferrite nyob rau hauv cheeb tsam weld yog tswj ntawm 3% -5%, zam qhov teeb meem rhiab heev ntawm tshav kub-cuam tshuam cheeb tsam ntawm cov pa austenitic stainless hlau vuam.
UNS N08031 phaj Economic thiab nqi zoo
Thawj qhov peev txheej ntawm Alloy 31 cov cuab yeej yog 40% siab dua li ntawm 316L, tab sis tus nqi tu (nrog rau kev poob qis) thaum lub sij hawm 8 lub neej tsuas yog 1/3 ntawm qhov kawg, thiab tag nrho cov nqi ntawm lub voj voog raug txo los ntawm 25%. Piv nrog rau Hastelloy C276, tus nqi yuav raug txo los ntawm 30% nyob rau hauv daim ntawv thov ntawm phosphoric acid cov tshuaj tiv thaiv tso tsheb hlau luam, thiab corrosion kuj lub neej yog ncua los ntawm 15%, nrog rau cov nqi zoo heev -effectiveness.
