Qhov sib txawv ntawm kev ua tau zoo thiab cov ntaub ntawv ntawm American cov txheej txheem square raj A500GR.B, C, D
Ua ntej, cia saib cov yam ntxwv ntawm American cov txheej txheem square raj A500Gr.Txhua kev cai lij choj siv cov qauv A500, thiab)) Txawm hais tias koj xav tau nws rau tsev qauv qauv, kev tsim kho tshuab, lossis lwm daim teb, peb txoj kab square tuaj yeem ua tau raws li koj cov kev xav tau.
Txawm li cas los xij, tseem muaj qee qhov sib txawv ntawm American cov txheej txheem square raj A500GR.B, C, thiab D. Ua ntej, ntawm qhov kev pom ntawm cov tshuaj muaj pes tsawg leeg, peb yog txawv me ntsis.
A500Gr.B muaj cov ntsiab lus roj carbon tsawg thiab yog tsim nyog rau cov kev thov tsim qauv. Cov ntsiab lus roj carbon ntau dua ntawm A500Gr.c muab nws zoo dua tensile lub zog thiab corrosion tsis kam, thiab yog qhov haum rau cov dej num uas yuav tsum muaj zog thiab lub zog siab dua. A500Gr.D Yuav nce cov ntsiab lus carbon, uas tuaj yeem muab cov txiaj ntsig ntau dua thiab haum rau cov phiaj xwm uas tiv thaiv ntau dua thiab thauj khoom.
Thib ob, los ntawm kev pom ntawm cov neeg kho tshuab, tseem muaj qhov sib txawv ntawm American cov txheej txheem square raj A500GR.B, C, thiab cov khoom hauv qab no yog lawv cov cuab yeej siv tshuab:
A500Gr.B: Lub zog qis ntawm 400Mpa, txo qis zog ntawm 235MPA, qis elongation ntawm 21%.
A500GR.C: Tsawg tensile lub zog ntawm 425Mpa, txo qis zog ntawm 315mpa, qis elongation ntawm 23%.
A500Gr.D: Lub zog tensile tsawg ntawm 485mpa, txo qis zog ntawm 345mpa, qis elongation ntawm 21%.
Ib qho ntxiv, A500GR.C thiab A500GR.D yog superior rau A500GR.B nyob rau hauv kev ua si txias. Yog tias koj qhov project yuav tsum tau khoov ntawm cov kab square, peb pom zoo xaiv A500GR.C lossis A500GR.D kom ntseeg tau qhov kev ua tau zoo dua.
Gnee pab pawg yog koj tus khub txhim khu kev qha thaum xaiv cov khoom siv square raj. Peb muaj kev paub nplua nuj thiab pab pawg hauv cov hlau, muab cov kab mob Asmeskas zoo square cov tub sab A500GR.B, C, D, raws li cov kev pab cuam tom qab muag.
