A283 Qib C hlau yog machinable nrog 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 hluav taws xob hluav taws xob hluav taws xob sib txuas ntauwd, txuas hniav, tsheb, boiler rauv, ntim, nkoj, thiab lwm yam., kuj tseem siv ntau tsawg raws li qhov yuav tsum tau ua rau cov khoom siv tshuab.
Dimensional Yam ntxwv ntawm Qib A Steels: Lub thickness siv tau rau cov khoom siv qib A raws li tau hais tseg hauv ASTM A283 pib los ntawm 6 hli mus rau 50 hli. Qhov dav feem ntau yog los ntawm 600 hli mus rau 2000 hli.
Chemical Composition ntawm Qib A Steels: ASTM A283 txhais cov tshuaj muaj pes tsawg leeg ntawm Qib A steels raws li hauv qab no:
Qhov feem pua siab tshaj ntawm Cov pa roj carbon (C) yog 0.14 ib
Qhov feem pua siab tshaj ntawm Silicon (Si) yog 0.4
Qhov feem pua siab tshaj ntawm Manganese (Mn) yog 0.9
Qhov feem pua siab tshaj ntawm Phosphorous (P) yog 0.035 ib
Qhov feem pua siab tshaj ntawm Sulfur (S) yog 0.040 ib
Tsawg feem pua ntawm Tooj (Cu) yog 0.20 ib
Cov seem yog hlau (Fe) feem pua thiab nrog ob peb yam tsis zoo
ASTM A285 yog ib hom zoo tib yam carbon steel npaj rau fusion-welded siab hlab ntsha equipments li boiler, cia tank, tshav kub exchangers, thiab lwm yam. Nrog 3 qib steel (Qib A, Qib B, Qib C) npog tensile zog ntau yam ntawm 310-515Mpa , feem ntau ASTM A285 steel phaj yog xa raws li-dov mob. ua los ntawm kev tua, semi-tua, capped lossis rimmed steel kev coj ua raws li cov neeg siv khoom kawg.
ASTM A285 steel tuaj yeem tsim rau hauv ntau cov khoom siv hlau, steel daim hlau, steel coil, steel yeeb nkab, nws muaj peev xwm weld-muaj peev xwm rau fusion weld xav tau rau cov khoom siv siab siab, nws cov thickness max yog txwv rau 50mm txhawm rau tiv thaiv nws cov cuab yeej cuab tam.
ASTM A283 yog tsim los ua ib hom carbon steel phaj rau lub hom phiaj dav dav, cov hlau no muaj zog tensile qis thiab nruab nrab, nws muaj 2 qib steel (Qib C, Qib D). Rau steel phaj ua los ntawm coils los yog tsis muaj kev kho cua sov, yuav tsum tau kuaj ntxiv rau nws cov kev ntxhov siab relieving, feem ntau tom qab steel coil yog decoiled, tshuaj xyuas, conditining, kev kho cua sov yuav tsum tau ua ntej xa. ASTM A283 tsuas yog siv rau lub hom phiaj ntawm cov qauv, thaum ASME SA283 / SA283M steel phaj kuj tseem siv tau rau hauv boiler thiab siab nkoj tsim khoom. Available ASTM A283 steel khoom daim ntawv npog steel phaj, steel coil, steel yeeb nkab, thiab cov khoom steel hlau raws li steel seem, kab teeb, yog tias koj xav yuav ASTM A283 steel phaj, tiv tauj peb tam sim no.
