O mea e faʻaaogaina i le gaosiga omate fa'ailogae aofia ai uamea, uamea sima carbide, carbide, zinc faavae alloys, mea polymer, alumini apamemea, maualuga ma le maualalo o mea liusuavai alloys ma isi.O le tele o mea e fa'aaogaina i le gaosiga o pa'u fa'ailoga e masani lava o le sila.O ituaiga masani o mea e faʻaaogaina mo vaega o loʻo galue o loʻo i ai: uʻamea meafaigaluega carbon, uʻamea meafaigaluega uʻamea maualalo, maualuga carbon maualuga poʻo le medium chromium meafaigaluega uamea, medium carbon alloy uamea, maualuga saoasaoa uamea, matrix uamea ma carbide, uamea sima carbide, ma isi.

1. Low-alloy meafaigaluega uamea

Uila meafaigaluega maualalo e faʻavae i luga o le carbon tool steel ma le faʻaopoopoga o le aofaʻi saʻo o elemene faʻafefiloi.Pe a faatusatusa i le uamea meafaigaluega carbon, faaitiitia le uiga o le ta'e ma tineia deformation, faaleleia le hardenability o uamea, ofuina tetee e sili atu foi.u'amea maualalo fa'aaogaina i le gaosiga o molds o CrWMn, 9Mn2V, 7CrSiMnMoV (code CH-1), 6CrNiSiMnMoV (code GD) ma isi.

2. Uamea meafaigaluega carbon

Le tele o talosaga i le faʻaogaina o le carbon tool steel mo T8A, T10A, ma isi, o le lelei o le lelei o le gaosiga o gaioiga, taugofie.Ae o le hardenability ma mumu maaa e matitiva, vevela togafitiga deformation, maualalo avega-tauave gafatia.

3. Uamea maualuga-saosaoa

Uamea maualuga-saosaoa e sili ona maaa, ofuina tete'e ma compressive malosi o le u'amea mold, maualuga avega-tauave gafatia.E masani ona faʻaaogaina i mamanu o le W18Cr4V (code 8-4-1) ma le itiiti ifo o le tungsten W6Mo5Cr4V2 (code 6-5-4-2, le United States brand M2) ma faʻaleleia le faigata o le atinaʻeina o le faʻaitiitia o le carbon vanadium high-speed steel. 6W6Mo5Cr4V (code 6W6 poʻo le maualalo o le carbon M2).E manaʻomia foʻi e le uʻamea maualuga le toe faʻaleleia e faʻaleleia ai le tufatufaina atu o carbide.

4. High-carbon medium-chromium mea faigaluega uamea

High-carbon medium-chromium meafaigaluega uʻamea faʻaaogaina mo molds o Cr4W2MoV, Cr6WV, Cr5MoV, ma isi, o latou chromium anotusi e maualalo, itiiti eutectic carbide, tufatufa carbide, vevela togafitiga deformation e laʻititi, ma le faʻamalosi lelei ma le mautu dimensional.Pe a faatusatusa i le carbide segregation e fai si ogaoga maualuga-carbon maualuga chromium sila, ua faaleleia le faatinoga.

5. High-carbon maualuga-chromium meafaigaluega uamea

E masani ona faʻaaogaina maualuga-carbon maualuga-chromium meafaigaluega uamea Cr12 ma Cr12MoV, Cr12Mo1V1 (code D2), latou te maua lelei hardenability, hardenability maofuina tete'e, vevela togafitiga deformation e matua itiiti lava, mo ofu maualuga tetee micro-deformation mold sila, tauaveina gafatia lona lua i le maualuga-saosaoa uʻamea.Ae o le carbide segregation e ogaoga, e tatau ona faifai pea ita (axial upsetting, radial drawing) e sui forging, ina ia faaitiitia le unevenness o carbide, faaleleia le faaaogaina o le faatinoga.

6. carbide sima ma uamea sima carbide

O le maaa ma le ofuina o le carbide sima e maualuga atu nai lo soʻo se isi lava ituaiga o uʻamea, ae o le malosi o le punou ma le faigata e leaga.O le carbide sima o loʻo faʻaaogaina mo molds o le tungsten ma le cobalt, ma mo faʻataʻitaʻiga e laʻititi le aʻafiaga ma le maualuga o le ofuina o mea e manaʻomia, e mafai ona faʻaaogaina se mea faʻapipiʻi pito i lalo ole cobalt.Mo fa'ailoga maualuga, e mafai ona fa'aogaina carbide e maualuga atu le cobalt.
