A283 A285 Kub kuav los tiag hlau phaj Txias kuav los tiag hlau phaj A36
A283 Qib C steel yog tshuab tau nrog rau kev ua haujlwm xws li txiav, sib tsoo thiab vuam.
Daim ntawv thov:
A283 Gr C hlau feem ntau yog siv los tsim cov chaw tsim khoom, cov khoom siv hluav taws xob muaj zog ntauwd ntauwd, Txuas hniav, tsheb, rhaub rhaub dej kub, ntim khoom, nkoj, thiab lwm yam.
Yam ntxwv ntawm Qib A Cov Hlau: Qhov tuab siv tau rau qib A cov khoom siv raws li tau hais tseg hauv ASTM A283 pib los ntawm 6 mm txog 50 mm. Qhov dav yog ib txwm los ntawm 600 mm txog 2000 mm.
Cov Tshuaj Muaj Tshuaj Qib Qib A Cov Hlau: ASTM A283 txhais cov tshuaj muaj pes tsawg leeg ntawm Qib A cov hlau raws li hauv qab no:
Feem pua ntawm Cov pa roj carbon (C) yog 0.14
Feem pua ntawm Silicon (Si) yog 0.4
Feem pua ntawm Manganese (Mn) yog 0.9
Feem pua ntawm Phosphorous (P) yog 0.035
Feem pua ntawm Leej faj (S) yog 0.040
Yam tsawg kawg nkaus ntawm Tooj liab (Cu) yog 0.20
Qhov seem yog hlau (Fe) feem pua thiab nrog ob peb yam tsis tsim nyog tsis pom zoo
ASTM A285 yog ib yam ntawm cov pa roj carbon zoo tib yam npaj rau fusion-welded siab txog ntsha khoom siv li boiler, cia tank, hloov pauv kub, thiab lwm yam. , feem ntau ASTM A285 steel phaj tau xa raws li cov xwm txheej. ua los ntawm kev tua, tua ib nrab, capped lossis rimmed steel kev coj ua raws li cov neeg siv kawg qhov xav tau.
ASTM A285 steel tuaj yeem tsim ua ntau yam khoom siv hlau, daim hlau, hlau hlau, hlau yeeb nkab, nws muaj qhov zoo weld-peev xwm rau fusion weld xav tau rau cov khoom siv nkoj siab, nws cov tuab tuab yog txwv rau 50mm txhawm rau txhawm rau pov hwm nws cov cuab yeej khoom siv
ASTM A283 tau tsim los ua ib hom ntawm cov pa roj carbon phaj rau lub hom phiaj kev ua haujlwm, cov hlau no muaj lub zog qis thiab nruab nrab lub zog, nws muaj 2 qib hlau (Qib C, Qib D). Rau cov phaj hlau ua los ntawm cov kauj lossis tsis muaj kev kho cua sov, yuav tsum muaj kev sim ntxiv rau nws qhov kev ntxhov siab, feem ntau yog tom qab cov hlau hlau tau kho kom zoo nkauj, tshuaj xyuas, sib xyaw, kho cua sov yuav tsum tau ua ntej xa khoom. ASTM A283 tsuas yog siv rau lub hom phiaj kev ua haujlwm, thaum ASME SA283/SA283M steel phaj kuj tseem tuaj yeem siv rau hauv lub rhaub dej thiab lub nkoj tsim khoom tsim khoom. Availlable ASTM A283 cov khoom lag luam hlau npog cov hlau phaj, cov hlau hlau, cov yeeb nkab hlau, thiab cov khoom siv hlau ua cov hlau, kab teeb, yog tias koj xav yuav ASTM A283 phaj hlau, tiv tauj peb tam sim no.
