Cov khoom thiab kev siv ntawm daim iav yas pwm steel PMS?
Daim iav yas pwm steel PMS yog ib yam ntawm cov khoom hnyav ua kom muaj hnub nyoog nyuaj, nrog cov iav zoo heev, kev ua tau zoo thiab kev ua kom sov, kev ua hluav taws xob thiab kev ua zoo rau txhua yam kev ua haujlwm.Heat kev kho yog yooj yim, (850 + 20) solution tov , (500 +) 10 ℃ tom qab kev laus kev kho mob, daim duab ntawm bainite thiab martensite duplex, kev kho kom sov sov deformation. Qhov chaw "phi 150 mm thickness or template" 150 hli hla ntawm lub koom haum, qhov sib npaug ntawm qhov sib npaug, kev kho khoom siv rau sigma> 980 mpa, 1200 mpa, sigma sigma b> 13%, sigma > 45%. Haum rau kev ua haujlwm ua kom sov li 300 ℃, siv 30 ~ 45 HRC hardness, siab iav ntsa, siab precision ntawm txhua hom pwm yas.
PMS daim iav yas pwm steel muaj zoo nitriding nto strengthening kev kawm.Qhov tawv hardness mus txog 800 ~ 1200HV tom qab kev kho nitride.
PMS steel yog siv txhua hom lens optics, suab thiab kaw suab hauv sab hauv thiab sab nraum lub thawv, xov tooj, xov tooj cua, lub quartz moos, tshuab ntxhua khaub ncaws, tsheb teeb tsheb thiab teeb thiab cov khoom siv hluav taws xob xws li txhua yam yas plhaub pwm.
