40Mn2 structural steel yeeb nkabyog ib tug nruab nrab carbon quenched thiab tempered manganese hlau. Lub zog, plasticity thiab hnav tsis kam ntawm cov hlau yog siab, thiab cov machinability thiab kev kho cua sov txheej txheem kev ua tau zoo kuj zoo. Qhov tseem ceeb hardenable txoj kab uas hla ntawm cov roj yog 8.5 ~ 23mm, thiab nyob rau hauv dej Qhov tseem ceeb hardened txoj kab uas hla mus txog 20 ~ 42mm; Txawm li cas los xij, nws muaj temper brittleness thiab overheating rhiab heev, thiab nws nquag tawg thaum quenching. Cov hlau no muaj qhov chaw dawb, tsis tshua muaj qhov txias deformation plasticity, thiab tsis zoo weldability. Nws yuav tsum tau preheated rau 100 ~ 425 degree ua ntej vuam.
45Mn2 nruab nrab carbon quenched thiab tempered steel yeeb nkab muaj lub zog siab, hnav tsis kam thiab hardenability. Qhov tseem ceeb hardenable txoj kab uas hla ntawm cov roj mus txog 10 ~ 25mm, thiab qhov tseem ceeb hardenable txoj kab uas hla hauv dej ncav cuag 22 ~ 45mm.
