Cr12MoV u'amea lapotopoto fa'aloloa vevela

O le u'amea Cr12MoV e maualuga lona malosi, ma oi latou o lo'o i ai se vaega fa'asaga i le 300 i le 400 mm pe itiiti e mafai ona tineia atoatoa.
E mafai ona fa'atumauina lelei le ma'a'a ma fa'aofuofu tete'e i le 300 ~ 400 ℃, o lona malosi e maualuga atu nai lo le u'amea Cr12, ma e la'ititi le suiga o le voluma i le taimi o le tineia. E mafai ona faʻaaogaina e gaosia ai faʻailoga eseese ma mea faigaluega faʻatasi ai ma vaeluaga tetele, foliga lavelave, ma faʻasaga i uta tetele. Mo se faʻataʻitaʻiga, tuʻi mate ma foliga lavelave, faʻaofi i luga o lavelave oti, uʻamea ata loloto mate, uaea ata oti, filo uaea filo, extrusion malulu mate, seleulu tipi malulu, ili liʻo, meafaigaluega masani, fua meafaigaluega, ma isi.
Cr12MoV uamea o se maualuga-carbon, maualuga-molybdenum lysic sila. O lona anotusi carbon e sili atu le maualalo nai lo le Crl2 uamea, ma ua faaopoopo i elemene molybdenum ma vanadium, lea e matua faaleleia atili ai le uamea o le gaosiga o meatotino, aafiaga faigata ma le tufatufaina carbide. O le uʻamea e maualuga le ofuina o le teteʻe, faʻamalosi, faʻamalosi, faigata, faʻamautu vevela, malosi faʻamalosi, faʻapea foʻi ma le micro deformation, lelei atoatoa faʻatinoga ma le tele o fetuunaiga. O le vevela faʻamaluluina o le vevela e 520 ℃. Ole lapo'a tipi e i lalo ole 4mm ma e mafai ona fa'ama'a'a atoa. O le ofuina o lenei uʻamea e 3 ~ 4 taimi e sili atu nai lo le faʻaogaina o se uʻamea meafaigaluega maualalo, ma e laʻititi le tele o le tineia. Faʻamalo loloto: suauʻu tineia 200 ~ 300mm.
I le faagasologa o le tioata, o le tele o carbide paʻepaʻe eutectic e fausia (o le vaega o mea carbonized e tusa ma le 20%, ma le vevela eutectic e tusa ma le 1150 ° C). O nei carbide e matua malō ma pala. E ui lava o le carbide e malepelepe i se tikeri faapitoa pe a uma le taʻavale, o le carbide e tufatufa atu i fusi, papa, poloka, ma faaputuga i luga o le taʻavale, ma o le tikeri o le vavaeeseina e faʻateleina i le lautele o le sila.
