Manhole npog
Khoom nthuav qhia:
Zoo toughness.Qhov cuam tshuam tus nqi zoo ib yam li cov khoom nruab nrab carbon steel, uas yog ntau tshaj 10 npaug ntawm cov khoom siv grey hlau.
Muaj zog corrosion kuj.Nyob rau hauv cov dej tsuag tshuaj tiv thaiv corrosion, tus nqi corrosion nyob rau hauv 90 hnub tsuas yog 1/40 ntawm cov yeeb nkab steel thiab 1/10 ntawm grey hlau yeeb nkab.Qhov kev pab cuam lub neej yog 2 zaug ntawm grey hlau yeeb nkab thiab 5. lub sij hawm zoo tib yam steel yeeb nkab.
Zoo plasticity.Elongation ≥7%, zoo ib yam li cov pa roj carbon siab, tab sis grey hlau cov khoom elongation yog xoom.
Lub zog siab.Qhov tensile lub zog ob ≥420MPa thiab tawm los lub zog OS ≥300MPa yog tib yam li cov pa roj carbon tsawg thiab peb zaug li cov khoom siv hlau grey.
Vim nws cov nodular graphite microstructure, ductile hlau yog zoo dua cam khwb cia hlau nyob rau hauv txo kev co muaj peev xwm, yog li nws muaj txiaj ntsig zoo los txo cov kev ntxhov siab.Ib qho laj thawj tseem ceeb rau kev xaiv cov hlau ductile yog cov hlau ductile nqi tsawg dua cam khwb cia hlau. hlau ua rau cov khoom no nrov dua, ua haujlwm zoo dua, thiab tsis tshua muaj nqi rau lub tshuab.
Lub zog ntawm ductile hlau yog piv rau cov hlau cam khwb cia hlau.Ductile hlau muaj lub zog tawm los ntau dua, nrog qhov tsawg kawg nkaus lub zog ntawm 40K thiab cam khwb cia steel yield zog ntawm tsuas yog 36K.Ductile hlau yog ntau resistant rau corrosion thiab oxidation dua cam khwb cia hlau nyob rau hauv feem ntau siv hauv nroog xws li dej, dej ntsev, chav dej, thiab lwm yam.
