Cov hlau feem ntau siv los ua cov tshuab siv lub zog yog quenched thiab tempered steel, hardened steel, carburized thiab hardened steel thiab nitrided steel. Lub zog ntawm cam khwb cia hlau iav yog me ntsis qis dua li ntawm forged steel iav, thiab nws feem ntau yog siv rau cov iav loj, grey cam khwb cia hlau muaj cov khoom siv tsis zoo thiab tuaj yeem siv rau hauv lub teeb-load qhib iav kis tau tus mob, cov hlau ductile tuaj yeem ua ib feem. hloov steel los ua lub zog.
Nyob rau hauv lub neej yav tom ntej, kev tsim kho machinery gears yog tsim nyob rau hauv cov kev taw qhia ntawm hnyav load, kev kub ceev, high precision thiab zoo heev efficiency, thiab siv zog ua kom me me, lub teeb nyob rau hauv hnyav, ntev nyob rau hauv lub neej thiab kev lag luam kev ntseeg.
