ASME SA515 Gr. 60 SA516 Gr. 70 Carbon Boiler Qib Steel Phaj Rau Cov Nkoj Siab

ASME SA515 Gr. 60 thiab SA516 Gr. 70 carbon boiler qib steel phaj yog dav siv nyob rau hauv kev tsim cov hlab ntsha siab, txhua tus muab cov yam ntxwv sib txawv thiab cov khoom uas cuam tshuam rau lawv qhov tsim nyog rau kev siv tshwj xeeb. Qhov kev sib piv ntawm qhov tob no yog txhawm rau pom qhov sib txawv thiab qhov zoo sib xws ntawm ob cov ntaub ntawv no los pab engineers thiab fabricators hauv kev txiav txim siab paub.

Thaum nws los txog rau tshuaj muaj pes tsawg leeg, ob qho tib si SA515 Gr. 60 thiab SA516 Gr. 70 tau tswj cov nyiaj carbon, manganese, silicon, phosphorus, thiab sulfur. Txawm li cas los xij, cov feem pua ​​​​ntau yam sib txawv. SA 516 gr. 70 feem ntau muaj cov ntsiab lus siab dua me ntsis, uas ua rau muaj zog ntxiv tab sis kuj tseem tuaj yeem cuam tshuam rau weldability rau qee qhov. Cov ntsiab lus manganese hauv ob qib ua lub luag haujlwm tseem ceeb hauv kev txhim kho hardenability thiab toughness.

Hais txog cov khoom siv kho tshuab, SA516 Gr. 70 feem ntau ua kom pom lub zog tensile zoo dua thiab lub zog tawm los piv rau SA515 Gr. 60. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav tsum muaj peev xwm thauj khoom ntau dua. Txawm li cas los xij, SA515 Gr. 60 tseem muaj lub zog txaus rau ntau daim ntawv thov cov hlab ntsha uas xav tau kev siv tshuab tsawg dua.

Lub microstructure ntawm ob qib no kuj txawv. SA 516 gr. 70 feem ntau nthuav tawm cov qauv nplej zoo dua, uas tuaj yeem txhim kho nws txoj kev tiv thaiv kev qaug zog thiab tawg. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov hlab ntsha siab uas raug rau kev thauj khoom cyclic thiab kev ntxhov siab.

Weldability yog qhov tseem ceeb rau kev txiav txim siab. SA 515 gr. 60 feem ntau suav tias yog qhov sib txuas ntau dua vim nws cov ntsiab lus qis dua, tab sis nrog cov txheej txheem vuam thiab cov txheej txheem, ob qib tuaj yeem ua tiav welded kom ua tiav cov suab nrov thiab txhim khu kev qha.

Hais txog kev kho cua sov, cov lus teb ntawm SA515 Gr. 60 thiab SA516 Gr. 70 tuaj yeem sib txawv. SA 516 gr. 70 tej zaum yuav xav tau kev kho cua sov ntau dua los ua kom zoo dua nws cov khoom siv kho tshuab, thaum SA515 Gr. 60 yog qhov kev zam txim ntau dua hauv qhov no.

Kev tiv thaiv corrosion ntawm cov qib no nyob ntawm ntau yam xws li ib puag ncig thiab kev kho saum npoo. Feem ntau, ob qho tib si tuaj yeem tiv thaiv los ntawm cov txheej txheem tsim nyog lossis cov khoom sib txuas ntxiv los txhim kho lawv cov kav ntev hauv cov kab mob corrosive.

Hais txog tus nqi, SA515 Gr. 60 feem ntau pheej yig dua, ua rau nws yog qhov kev xaiv zoo nkauj thaum tus nqi yog qhov tseem ceeb yam tsis muaj kev cuam tshuam qhov tseem ceeb. SA 516 gr. 70, ntawm qhov tod tes, tuaj yeem hais kom tus nqi siab dua vim nws cov khoom siv kho kom zoo dua qub.

Daim ntawv thov scenarios rau ob qib no kuj txawv raws li lawv cov khoom. SA 515 gr. 60 feem ntau yog siv rau hauv cov hlab ntsha uas tsis tshua muaj siab lossis cov uas ua haujlwm ntawm qhov kub thiab txias. SA 516 gr. 70 tau txais kev pom zoo rau ntau daim ntawv thov, xws li cov hlab ntsha siab lossis cov uas raug kev ua haujlwm hnyav.

Txhawm rau xaus, kev xaiv ntawm ASME SA515 Gr. 60 thiab SA516 Gr. 70 carbon boiler qib steel daim hlau rau cov hlab ntsha siab yog nyob ntawm kev soj ntsuam kom zoo ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov, suav nrog kev ntxhov siab, kev ua haujlwm, kev tsim khoom, kev txwv tus nqi, thiab kev xav tau corrosion. Kev nkag siab zoo ntawm cov khoom siv thiab lawv qhov cuam tshuam yog qhov tseem ceeb rau kev xaiv txoj cai thiab ua kom muaj kev nyab xeeb thiab ua tau zoo ntawm cov hlab ntsha siab.
