A516Gr70 siab steel phaj Qhia ntxaws qhia
ASTM A516 Gr 70 yog cov khoom siv hluav taws xob kub-resistant siab lub nkoj uas ua tau raws li cov qauv tsim los ntawm American Society for Materials and Testing (ASTM). Nws muaj cov khoom siv zoo thiab kev tiv thaiv corrosion, yog li nws yog dav siv hauv petrochemical, tshuaj, nkoj tsim, boiler thiab lwm yam.
ASTM A516 Gr70 tus qauv siv
ASTM A516 yog ib feem ntawm ASTM International Standard thiab suav nrog ntau qib sib txawv ntawm cov cua kub-resistant siab cov hlab ntsha steels. Ntawm lawv, A516 Gr 70 yog qhov nruab nrab thiab qis kub kub resistant siab lub nkoj steel, nws cov qauv siv suav nrog cov khoom siv kho tshuab, tshuaj muaj pes tsawg leeg, kev kho cua sov thiab lwm yam kev cai. Hauv kev siv tus qauv, nws muaj cov ncauj lus kom ntxaws txog nws lub zog tensile, yield zog, elongation, cuam tshuam kev ua haujlwm, thiab lwm yam, kom ntseeg tau tias nws muaj kev ruaj khov thiab txhim khu kev qha thaum siv.
Cov tsis tseem ceeb ntawm A516Gr70 siab steel phaj yog raws li nram no
Tshuaj muaj pes tsawg leeg
Hais txog cov khoom siv kho tshuab, tus qauv xav tau A516 Gr 70 kom muaj qhov tsawg kawg nkaus lub zog ntawm 260MPa, lub zog tensile yam tsawg kawg nkaus ntawm 485 txog 620MPa thiab qhov tsawg kawg nkaus elongation ntawm 21. Cov kev cai nruj ntawm cov kev txwv no qhia tau tias A516 Gr 70 muaj zoo zog thiab plasticity thaum raug kub thiab siab ib puag ncig, uas tuaj yeem ua kom muaj kev nyab xeeb ntawm lub thawv. Cov tshuaj muaj pes tsawg leeg thiab kev kho cua sov yuav tsum tau ua kom zoo corrosion kuj thiab cov khoom ua haujlwm, ua rau nws haum rau ntau qhov chaw ua haujlwm hnyav.
Hauv kuv lub tswv yim, cov kev cai nruj ntawm ASTM A516 Gr 70 tus qauv siv yog qhov lav ntawm nws qhov kev ua tau zoo tshaj. Raws li lub tshav kub-resistant siab lub nkoj steel, nws yog tsuas yog siv los tiv taus kub thiab siab kub ua hauj lwm ib puag ncig, yog li nws lub zog, plasticity thiab corrosion kuj tseem ceeb heev. Kev siv cov qauv, kom A516 Gr 70 muaj kev sib koom ua ke thiab cov qauv, kom ntseeg tau tias nws cov khoom zoo thiab kev nyab xeeb. Kev ua raws li cov qauv tseem muab cov kev taw qhia thiab kev siv rau kev lag luam, uas pab txhawb kev tsim qauv thiab kev tsim qauv ntawm kev lag luam.
