ASTM A334 Tsawg kub carbon steel yeeb nkab
ASTM A334 carbon steel yeeb nkabyog ib qho tshwj xeeb tsim alloy steel yeeb nkab nrog ntxiv cov ntsiab lus ntawm manganese, molybdenum thiab silicon kom nce nws lub zog thiab kav ntev. Cov yeeb nkab steel no kuj muaj kev tiv thaiv corrosion zoo heev, txhim kho kev ua tau zoo tom qab kev kho cua sov, thiab muaj kev weldability zoo heev.
Raws li cov ntawv thov sib txawv, ASTM A334 seamless carbon steel kav muab faib ua ntau qib, suav nrog Qib 1, Qib 3, Qib 4, Qib 6, Qib 7, Qib 8 thiab Qib 9. Txhua qib yog tsim los ua kom tau raws li qhov tshwj xeeb ntawm cov hlab ntsha. yuav tsum tau ua kom tau raws li qhov sib txawv ntawm qhov kub thiab txias.
A334 carbon steel round raj ua tau zoo hauv kev tawm dag zog, nws tus nqi tsis tsawg dua 345N / mm ^ 2. Nyob rau hauv cov nqe lus ntawm tensile zog, nws elongation A mus txog 21%, qhia zoo plasticity.
Raws li qhov kub tsis tshua muaj seamless steel yeeb nkab, A334 qis temp carbon steel yeeb nkab yog normalized los yog normalized thiab tempered rau optimize nws cov kev ua tau zoo. Cov yeeb nkab steel no feem ntau yog nthuav tawm nyob rau hauv cov xwm txheej no thaum xa khoom, ua kom nws ruaj khov thiab kev ntseeg siab nyob rau hauv qhov kub thiab txias.
