1. Ububiko kugirango uhindure intego yiki gika
H13 bapfa ibyumaikoreshwa mugukora impimbano ipfa hamwe ningaruka zikomeye, gusohora bishyushye bipfa, guhimba neza bipfa;gupfa-gupfa bipfa kuri aluminium, umuringa hamwe na alloys.

Nugutangiza H13 kuzimya ikirere gikomera akazi gashyushye gupfa ibyuma biva muri Amerika.Imiterere n'imikoreshereze yabyo birasa cyane nibyuma bya 4Cr5MoSiV, ariko kubera ubwinshi bwa vanadium, ubushyuhe bwayo bwo hagati (dogere 600) imikorere iruta ibyuma 4Cr5MoSiV.Nicyiciro cyicyuma gihagarariwe hamwe ningeri nyinshi zikoreshwa mubikorwa bishyushye bipfa ibyuma.
2. Ibiranga
Electroslag yahinduye ibyuma, ibyuma bifite ubukana bwinshi kandi birwanya ubushyuhe bwumuriro, ibyuma birimo ibintu byinshi bya karubone na vanadium, kwihanganira kwambara neza, gukomera gukabije, no kurwanya ubushyuhe bwiza.Ku bushyuhe bwo hejuru, bufite imbaraga nubukomezi bwiza, kwihanganira kwambara no gukomera, ibintu byiza byuzuye byubukanishi hamwe nubushyuhe bukabije bwo guhangana.
3. Ibigize imiti yibyuma
Icyuma cya H13 nicyuma C-Cr-Mo-Si-V, gikoreshwa cyane kwisi.Muri icyo gihe, intiti nyinshi zo mu bihugu bitandukanye zakoze ubushakashatsi bwimbitse kuri yo kandi zirimo gukora ubushakashatsi ku kunoza imiterere y’imiti.Ibyuma bikoreshwa cyane kandi bifite ibimenyetso byiza cyane, bigenwa ahanini nubumara bwibyuma.Birumvikana ko ibintu byanduye mubyuma bigomba kugabanuka.Amakuru amwe yerekana ko iyo Rm ari 1550MPa, sulfure yibikoresho bigabanuka kuva 0.005% bikagera kuri 0.003%, ibyo bikazongera ubukana bwingaruka kuri 13J.Ikigaragara ni uko igipimo cya NADCA 207-2003 giteganya ko ibirimo sulfure yibyuma bya premium H13 bigomba kuba munsi ya 0.005%, mugihe sulfure yo hejuru igomba kuba munsi ya 0.003% S na 0.015% P.Ibigize ibyuma bya H13 byasesenguwe hepfo.

Carbone: Abanyamerika AISI H13, UNS T20813, ASTM (verisiyo iheruka) H13 na FED QQ-T-570 H13 ibyuma birimo karubone ya (0.32 ~ 0.45)%, ikaba irimo karubone nyinshi muri byoseH13 ibyuma.Mugari.Ibirimo bya karubone byo mu Budage X40CrMoV5-1 na 1.2344 ni (0.37 ~ 0.43)%, kandi ibipimo bya karubone ni bike.Mu kidage DIN17350, ibirimo karubone ya X38CrMoV5-1 ni (0.36 ~ 0.42)%.Ibirimo karubone ya SKD 61 mu Buyapani ni (0.32 ~ 0.42)%.Ibirimo bya karubone bya 4Cr5MoSiV1 na SM 4Cr5MoSiV1 mu gihugu cyanjye GB / T 1299 na YB / T 094 ni (0.32 ~ 0.42)% na (0.32 ~ 0.45)%, bihwanye na SKD61 na AISI H13.By'umwihariko, twakagombye kwerekana ko ibipimo bya karubone biri mu byuma bya H13 mu ishyirahamwe ry’amajyaruguru ya Die Die Casting Association NADCA 207-90, 207-97 na 207-2003 byerekanwe nka (0.37 ~ 0.42)%.

Ibyuma bya H13 birimo 5% Cr bigomba kugira ubukana buhanitse, bityo ibirimo C bigomba kubungabungwa kurwego rugizwe nubunini buke bwimvange C.Woodyatt na Krauss berekanye ko ku gishushanyo mbonera cya Fe-Cr-C kuri 870 ℃, umwanya wibyuma bya H13 ni byiza aho uhurira na austenite A na (A + M3C + M7C3) uturere twibyiciro bitatu.Ibirimo C bihuye ni 0.4%.Igishushanyo cyanagaragaje ubwiyongere bwa C cyangwa Cr kugirango bongere umubare wa M7C3, hamwe nicyuma cya A2 na D2 hamwe n’imyambarire myinshi yo kugereranya.Ni ngombwa kandi gukomeza ibintu biri munsi ya C kugira ngo Ms point yicyuma ifate urugero rwubushyuhe buringaniye (Madamu wa H13 ibyuma bisobanurwa ko ari 340 ℃), kugirango ibyuma bishobore kuzimya ubushyuhe bwicyumba.Shakisha ibinyomoro C bivanze cyane cyane bigizwe na martensite wongeyeho umubare muto wibisigisigi A hamwe nogusaranganya umwe, hanyuma ubone imiterere ya martensite imwe nyuma yo gutwarwa.Irinde guhindura cyane austenite yagumishijwe kubushyuhe bwakazi kugirango bigire ingaruka kumikorere cyangwa guhindura imikorere.Ingano ntoya ya austenite yagumishijwe igomba guhinduka rwose muburyo bubiri cyangwa butatu bwo gutuza nyuma yo kuzimya.Nkuko byavuzwe, herekanwa hano ko imiterere ya martensite yabonetse nyuma yo kuzimya ibyuma bya H13 ni lath M + umubare muto wa flake M + umubare muto wibisigisigi A. Carbide nziza cyane ya karibide yaguye kuri lath M nyuma yo gutwarwa.Intiti zo murugo nazo zakoze akazi
