Tshuaj muaj pes tsawg leeg thiab lub cev muaj zog
Chemical composition:
Cov khoom tseem ceeb ntawm Hastelloy C22 thiab Hastelloy C276 muaj xws li npib tsib xee, chromium, molybdenum, hlau thiab tungsten. Cov tshuaj muaj pes tsawg leeg ntawm C22 suav nrog: Ni 59%, Cr 20%, Mo 16%, Fe 3%, W 2%.
Cov tshuaj muaj pes tsawg leeg ntawm C276 suav nrog: Ni 63%, Cr 20%, Mo 16%, Fe 3%, C 0.015%.
Lub cev muaj zog: Ob lub alloys muaj qhov ceev ntawm 8.9 g / cm³ thiab melting point ntawm 1325-1370 degree . Tus kheej-corrosion peev xwm ntawm Hastelloy C22 hauv HNO₃ yog ntau dua li qhov hauv HCl, vim tias cov tshuaj tiv thaiv cathode ntawm HNO₃ ua rau muaj peev xwm sib npaug ntau dua ntawm NO / NO₂.
Corrosion kuj:Hastelloy C22 ua tau zoo nyob rau hauv ntau yam corrosive media, tshwj xeeb tshaj yog rau tuav cov kua qaub thiab muaj zog hauv paus, xws li nitric acid thiab sulfuric acid.
C276 muaj zog corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv oxidizing media, thiab nws cov ntsiab lus chromium siab ua rau nws tiv taus oxidizing thiab txo cov kua qaub. C276 tseem tiv taus corrosion los ntawm cov tshuaj chlorine moist, hypochlorite thiab chlorine dioxide daws.
Kev siv thaj chaw:
Hastelloy C22 feem ntau siv nyob rau hauv ib puag ncig uas tuav cov kua qaub thiab cov hauv paus muaj zog, xws li kev lag luam tshuaj thiab tshuaj.
C276 yog tsim rau ntau yam kev lag luam chemical industries uas muaj oxidizing thiab txo cov xov xwm, tshwj xeeb tshaj yog nyob rau hauv mixed acid ib puag ncig, xws li cov yeeb nkab tawm ntawm lub flue gas desulfurization system.
Mechanical zog tensile zog thiab yield zog:
Hastelloy C22 muaj lub zog tensile ntawm 690 MPa, yield zog ntawm 283 MPa thiab elongation ntawm 40% ntawm chav tsev kub. Kuj tseem muaj cov ntaub ntawv ntxaws ntxaws ntawm cov khoom siv kho tshuab ntawm C276 ntawm qhov kub sib txawv. Piv txwv li, ntawm -196 degree, lub zog tawm los yog 565 MPa, lub zog tensile yog 965 MPa, thiab elongation yog 45%.
