65Mn kub dov steel puag ncig tuav

65Mn steel yog Suav GB txheem caij nplooj ntoos hlav steel qib, Manganese (Mn) txhim kho hardenability, yog li lub zog, hardness, elasticity thiab hardenability yog siab dua li ntawm 65 # steel, tab sis nws muaj overheat rhiab heev thiab temper brittleness. Cov dej quenching zoo li tsim cov kab nrib pleb. Lub xeev annealed muaj zoo machinability, tsis tshua muaj txias deformation plasticity, thiab weldability tsis zoo.
65Mn siab carbon steel yog tsuas yog siv nyob rau hauv kev tsim ntawm ntau yam me me-section ca springs, round springs, clockwork, thiab lwm yam. Nws kuj yuav siv tau los tsim lub caij nplooj ntoos hlav rings, valve springs, shock absorbers, clutch reeds thiab nres springs.
