1. High-quality carbon steel structural steels xws li carbon steel 35, 45, 50, thiab lwm yam. Vim muaj kev ua haujlwm zoo txhua yam, lawv muaj ntau daim ntawv thov. Ntawm lawv, 45 steel yog siv dav tshaj plaws. Txhawm rau txhim kho nws cov khoom siv kho tshuab, qhov hluav taws kub zoo yuav tsum tau ua. Yog tias nws tsis tseem ceeb lossis me dua, cov khoom siv carbon steel xws li Q235 thiab Q275 tuaj yeem siv.
2. Alloy steel alloy steel muaj cov cuab yeej siv siab, tab sis tus nqi yog kim dua, thiab nws feem ntau yog siv rau axes nrog cov kev cai tshwj xeeb. Piv txwv li, lub siab ceev axis nrog zawv zawg kabmob, qis-carbon alloy qauv steel xws li 20CR thiab 20CRMNTI, uas tuaj yeem txhim kho tom qab carburizing thiab quenching. High-temperature mechanical kev ua tau zoo, feem ntau siv alloy qauv steel xws li 40CRNI thiab 38CRMOALA. Qhov ntxhib ntawm cov ncej yog nyiam los ntawm forging, ua raws li cov hlau; cov uas muaj qhov loj me los yog cov txheej txheem nyuaj tuaj yeem txiav txim siab cam khwb cia hlau lossis pob number case cam khwb cia hlau. Piv txwv li, kev siv cov pob thiab cov number case cam khwb cia hlau los tsim cov crankshafts thiab camshafts, uas muaj qhov zoo ntawm tus nqi qis, kev co zoo, tsis tshua muaj siab, thiab kev siv zog zoo dua. Cov qauv siv tshuab ntawm cov ncej yog kab teeb thiab feem ntau ntawm lawv yuav tsum tig, yog li nws txoj kev ntxhov siab feem ntau yog sib npaug. Cov ntaub ntawv ua tsis tau zoo yog: qaug zog so, overload so, thiab ntau elastic deformation. Qee qhov chaw nrog lub log hubs feem ntau yog ntsia rau ntawm ncej, yog li feem ntau cov ncej yuav tsum tau ua rau hauv cov ncej ncej, thiab qhov txiav ntim loj.
