Cov khoom ntawm EQ491 cav camshaft yog chromium-molybdenum alloy cam khwb cia hlau, thiab nws cov tshuaj muaj pes tsawg leeg yog qhia nyob rau hauv Table 1.
Table 1 Tshuaj muaj pes tsawg leeg w (%) ntawm chromium-molybdenum alloy cam khwb cia hlau

Cov qauv metallographic ntawm chromium-molybdenum alloy cam khwb cia hlau camshaft ua ntej cua sov yog hom B graphite + nplua pearlite + mesh carbide.
Lub cam blank yog raug rau induction cua sov quenching nyob rau hauv lub as-casting xeev. Cov kev xav tau rau quenching yog deg hardness ntawm 50-60HRC, peach tip hardened txheej tob ntawm 4.6mm-10.0mm, thiab puag ncig hardened txheej tob ntawm 1.5mm-8.0mm.
