Dab tsi yog qhov sib txawv ntawm astm A500 thiab A672 kav dej
ASTM A500 thiab AVTM A672 yog ob qho qauv sib txawv ntawm cov kav hlau sib txawv, uas txawv hauv lawv cov kev siv thiab kev ua haujlwm:
ASTM A500 STEEL YEE:
Lub ATTM A500 tus qauv tsuas yog txhais cov cai rau puag ncig, square thiab plaub kab hlau ua los ntawm cov hlau ferrous (feem ntau cov hlau thiab cov hlau me me).
Xws li cov kav hlau hlau feem ntau siv hauv cov ntawv thov cov txheej txheem xws li txuas hniav, vaj tse, thiab lwm yam qauv kev txhawb nqa uas yuav tsum muaj zog thiab kav ntev.
A500 cov kav hlau hlau yog siv dav hauv cov rwj hauv boilers, cov khoom siv thav duab, thiab lwm cov qauv hauv tsev vim lawv cov kev qhia tshwj xeeb thiab qib siab.
ASTM A672 Yeeb Nkab Hlau:
Lub ASTM A672 tus qauv yog tshwj xeeb rau tsawg-alloy high-zog steel kav, uas feem ntau siv nyob rau hauv cov ntawv thov kev ua haujlwm zoo xws li txhim kho tsev thiab txuas hniav.
Hom yeeb nkab hlau feem ntau muaj zog dua thiab lub zog zoo dua thiab tuaj yeem tiv thaiv ntau dua cov khoom siv.
A672 kav hlau feem ntau siv los ua cov ntawv thov steel, haum rau cov ntawv thov uas xav tau lub zog siab thiab kev ua haujlwm vuam zoo.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm A500 thiab A672 kav hlau nyob hauv lawv thaj chaw thov thiab cov khoom siv lub cev. A500 steel yeeb yog siv rau cov qauv tsim qauv, thaum A672 yeeb nkab muaj ntau dua rau cov kev ua haujlwm siab uas yuav tsum muaj. Thaum xaiv ib hom yeeb nkab tshwj xeeb, nws yog qhov tsim nyog los txiav txim siab raws li kev thov cov xwm txheej tiag tiag thiab kev ua tau zoo.
