Cov pa roj carbon steel
① Tus lej hlau yog "T" kom tsis txhob sib xyaw nrog lwm cov hlau.
② Cov naj npawb ntawm cov hlau qhia cov ntsiab lus carbon, uas yog sawv cev los ntawm ob peb txhiab ntawm cov ntsiab lus tsis sib xws. Piv txwv li, "T8" txhais tau hais tias cov ntsiab lus tsis sib xws yog 0.8%.
③ Cov ntsiab lus siab manganese tau sau tias "MN" tom kawg ntawm tus lej hlau, xws li "T8MN".
④ Cov phosphorus thiab sulfur cov ntsiab lus ntawm qib high-qib siab-zoo carbon cuab yeej hlau yog qis dua li cov khoom siv zoo carbon steel. Tsab ntawv "A" tom kawg ntawm tus lej hlau tau ntxiv los qhia qhov txawv, xws li "T8MNA".
Carbon steel qauv
① Nws yog tsim los ntawm Q + digital + zoo qib cim + deoxylonic cim cim. Nws cov hlau yog crowned nrog "Q", uas sawv cev rau lub ntsiab lus ntawm cov hlau. Cov lej hauv qab no qhia tus nqi ntawm qhov taw tes tawm los. Chav tsev yog MPA, xws li Q235 los qhia cov qauv hlau nrog 235 MPA.
② Cov cim uas qhia txog qib zoo thiab deoxygers tuaj yeem raug cim tom qab tus lej hlau. Cov cim qib zoo yog A, B, C, thiab D, raws li. Txoj kev deoxidation cim F txhais tau hais tias boiling steel, B sawv cev rau semi-txhais hlau, Z sawv cev rau lub suab hlau, TZ qhia tshwj xeeb taboo steel, calming steel tsis cim lub cim, uas yog, ZT thiab TZ tsis tau cim. Piv txwv li, Q235-AF sawv cev rau A-chav boiling hlau.
③ Cov pa roj carbon steel nrog kev siv tshwj xeeb, xws li choj hlau, nkoj hlau, thiab lwm yam, siv cov pa roj carbon -structural steel sawv cev txoj hauv kev, tab sis ntxiv tsab ntawv siv nyob rau hauv kawg ntawm cov hlau tooj.
High-quality carbon qauv steel
① Tus lej thib ob ntawm tus lej pib ntawm tus lej steel sawv cev rau cov ntsiab lus carbon ntawm cov hlau, uas tau qhia nyob rau hauv ob peb feem pua ntawm cov ntsiab lus carbon. No. 45 steel.
② Cov pa roj carbon zoo steel nrog cov ntsiab lus siab manganese yuav tsum tau cim nrog manganese ntsiab, xws li 50mn. ③ Boiling steel, semi-calf steel, thiab high-zoo carbon qauv steel nrog tshwj xeeb siv yuav tsum tau tshwj xeeb cim nyob rau hauv lub kawg ntawm cov hlau tooj. Piv txwv li, ib tug semi-definition steel nrog ib tug uniform carbon ntsiab lus ntawm 0.1%, thiab nws cov hlau tooj yog 10B.
