Qhov sib txawv ntawm Astm A588 qib B steel phaj thiab Astm A588 Qeb Ib Lub Phaj Steel
Tshuaj lom neeg cov tshuaj:ASTM A588 QIB QIB OB STEEN phiaj thiab qib B steel daim hlau muaj cov khoom siv tshuaj sib txawv. Qeb ib daim hlau muaj kwv yees li 0.20-0.55% tooj liab, thaum qib qib B cov phiaj muaj cov ntsiab lus tooj liab ntau dua li 0.25-0.65%.
Ib qho ntxiv, qib bit bit yuav muaj ntau qib tsib caug dua (NI) thiab chromium (CR). Cov kev sib txawv no cuam tshuam rau cov phiaj 'corrosion tsis kam thiab cov khoom siv mechanical.
Cov Khoom Siv Neeg Kho Tshuab:ASTM A588 Qib B Hlau Phaj Cov Khoom Taw Qhia Lub Zog Ntawm 485 -620 MPa ntau dua lossis sib npaug ntawm 345 MPa, Tensile Lub Zog 485-620 mpa). Qhov no qhia tau qib b grit muaj lub zog zoo dua thiab tawv hauv cov nra hnyav.
Dabtsi yog khoov kev ua haujlwm:Due to their higher strength characteristics, ASTM A588 Grade B plates typically require preheating for bending operations involving thicknesses >25mm lossis nruj bend radii. Qeb ib daim hlau, txawm li cas los xij, xav tau me me lossis tsis muaj preheating nyob rau hauv tib qho kev mob, ua rau lawv yooj yim dua los ua.
Cov Ntawv Thov:ASTM A588 qib B steel phaj, nrog nws lub zog dua, feem ntau yog siv cov cuab yeej siv cov txheej txheem siab dua 100 me}}} {sawv kev txhim kho kom ruaj ntseg, thiab yees.
ASTM A588 Qib ACov phaj steel yog cov qauv siv ntau dua hauv cov ntawv thov dav dav, suav nrog cov chaw khaws khoom, teeb tsa {{duty wrectures, thiab cov cuab yeej siv.
Nws yog ib qho tseem ceeb kom nco ntsoov tias ob qho tib siASTM A588 Qib AThiab qib B steel phiaj nthuav qhia zoo heev corrosion, ua tiav rau antm g101 kuaj, ua rau lawv haum rau sab nraum zoov lossis nthuav dav ib puag ncig.
Thaum xaiv cov qhab nia hlau, yuav tsum yog ua raws li kev ntsuam xyuas qhov project uas yuav tsum tau ua, tuab, kev ua si ib puag ncig, thaum ib txwm ua rau cov qauv thiab cov ncauj lus tshwj xeeb.
