420J1 420J2 fasi uamea uamea
Fa'amatalaga Puupuu:
420J1 ma 420J2 fasi uamea u'amea e lua ituaiga masani o mea u'amea u'amea e patino i le martensitic uʻamea uʻamea faasologa. E iai a latou eseesega i le tuufaatasiga o vailaʻau ma uiga. O se aotelega puupuu lenei o mea taitasi:
1. 420J1 fasi uamea stainless: 420J1 o se uamea stainless steel maualalo ma le maaa maualuga ma le malosi. O lona vaila'au vaila'au e masani ona aofia ai le 0.16-0.25% carbon, e uiga i le 1% chromium, ma le itiiti o le molybdenum. 420J1 e ofoina atu lelei le pala, tipi faʻatinoga, ma mea e olo ai. E masani ona faʻaaogaina mo le faia o naifi, mea fai taotoga, vaega faʻainisinia, ma nisi faʻaoga faʻafefe.
2. 420J2 uamea uamea fasimea: 420J2 o se medium-carbon uʻamea uamea ma maualuga maaa ma ofuina tetee. O lona vaila'au vaila'au e masani ona aofia ai le 0.26-0.35% carbon ma le 1% chromium. 420J2 o loʻo i ai le maualuga o le carbon content pe a faʻatusatusa i le 420J1, e mafua ai le faʻateleina o le maaa ma le tipiina o galuega. E masani ona faʻaaogaina mo le gaosiga o naifi, lau, mea fai taotoga, puna, ma nisi vaega masini.
