51crv4 Caij nplooj ntoos hlav steel hlau

Nta thiab Scope ntawm daim ntawv thov:

51CrV4 (1.8159) lub caij nplooj ntoos hlav steel muaj cov khoom siv zoo thiab cov txheej txheem kev ua tau zoo, kev ua haujlwm siab hardenability, ntxiv vanadium los kho cov nplej ntawm cov hlau, txo qis superheat rhiab heev, txhim kho lub zog thiab toughness, siab qaug zog, yield ratio siab dua, tab sis tsis zoo weldability, txias vim tsawg deformation plasticity. Lub 51CrV4 yog lub caij nplooj ntoos hlav qib siab uas siv los ua lub caij nplooj ntoo hlav tseem ceeb uas muaj qhov sib tw loj thiab lub caij nplooj ntoos hlav valve, lub caij nplooj ntoos hlav piston, thiab kev nyab xeeb valve caij nplooj ntoos hlav nrog kev ua haujlwm kub< 300="" °="">

51CrV4 caij nplooj ntoos hlav steel tshuaj muaj pes tsawg leeg:
