1. Hindura kugira ngo uhindure intego y'iki gika
Icyuma cya H13ikoreshwa mu gukora imashini zikora ibikoresho byo gucura zifite umuvuduko mwinshi, imashini zishyushye zo gusohora, imashini zikora ibikoresho byo gucura neza; imashini zikora ibikoresho byo gucura zikoresheje aluminiyumu, umuringa n'ibindi bikoresho byazo.

Ni icyuma gishyushye gikoreshwa mu gutwika H13 air quench gituruka muri Leta Zunze Ubumwe za Amerika. Imiterere yacyo n'ikoreshwa ryacyo ni bimwe n'iby'icyuma cya 4Cr5MoSiV, ariko kubera ko gifite vanadium nyinshi, imikorere yacyo iri hagati (dogere 600) ni myiza kurusha icyuma cya 4Cr5MoSiV. Ni icyuma gikoreshwa mu gutwika gifite uburyo butandukanye bwo gukoresha mu gutwika.
2. Ibiranga
Icyuma cyashongeshejwe na electroslag, icyuma gifite ubushobozi bwo gukomera no kudacika kw'ubushyuhe, icyuma gifite ingano nyinshi ya karuboni na vanadium, gifite ubushobozi bwo kwangirika neza, gifite imbaraga nkeya, kandi gifite ubushobozi bwo kudacika ku bushyuhe. Iyo ubushyuhe buri hejuru, gifite imbaraga n'ubukana byiza, gifite ubushobozi bwo kudacika no gukomera cyane, gifite ubushobozi bwo gukora neza mu buryo burambuye kandi kidacika intege cyane.
3. Imiterere y'ibinyabutabire by'icyuma
Icyuma cya H13 ni icyuma cya C-Cr-Mo-Si-V, gikoreshwa cyane ku isi. Muri icyo gihe, intiti nyinshi zo mu bihugu bitandukanye zakoze ubushakashatsi bwimbitse kuri cyo kandi zirimo gushakisha uburyo imiterere ya shimi irushaho kuba myiza. Icyuma gikoreshwa cyane kandi gifite imiterere myiza, ahanini iterwa n’imiterere ya shimi y’icyuma. Birumvikana ko umwanda uri mu cyuma ugomba kugabanuka. Amakuru amwe agaragaza ko iyo Rm ari 1550MPa, ingano ya sulfure mu bikoresho igabanuka kuva kuri 0.005% ikagera kuri 0.003%, ibyo bikazongera ubukana bw’ingaruka ku kigero cya 13J. Birumvikana ko amahame ya NADCA 207-2003 avuga ko ingano ya sulfure mu cyuma cya H13 cyo hejuru igomba kuba munsi ya 0.005%, mu gihe ingano ya sulfure ya superior igomba kuba munsi ya 0.003%S na 0.015%P. Ingano ya H13 irasesengurwa hano hepfo.

Karuboni: Icupa rya Amerika rya AISI H13, UNS T20813, ASTM (version iheruka) H13 na FED QQ-T-570 H13 bifite ingano ya karuboni (0.32 ~ 0.45)%, ari na ryo ngano ya karuboni nyinshi kurusha izindi zose.Ibyuma bya H13. Ubugari. Ingano ya karuboni ya X40CrMoV5-1 yo mu Budage ni (0.37~0.43)%, kandi ingano ya karuboni ni nto. Muri DIN17350 yo mu Budage, ingano ya karuboni ya X38CrMoV5-1 ni (0.36~0.42). Ingano ya karuboni ya SKD 61 mu Buyapani ni (0.32~0.42). Ingano ya karuboni ya 4Cr5MoSiV1 na SM 4Cr5MoSiV1 muri GB/T 1299 na YB/T 094 yo mu gihugu cyanjye ni (0.32~0.42)% na (0.32~0.45)%, aribyo SKD61 na AISI H13, uko bikurikirana. By’umwihariko, hakwiye kugaragazwa ko ingano ya karuboni mu cyuma cya H13 mu bipimo ngenderwaho bya NADCA 207-90, 207-97 na 207-2003 byagenwe nka (0.37~0.42)%.

Icyuma cya H13 kirimo 5% Cr kigomba kugira ubukomere bwinshi, bityo ingano yacyo ya C igomba kugumana ku rwego rukora ingano nto y’ibinyabutabire bya C. Woodyatt na Krauss bagaragaje ko ku gishushanyo mbonera cya Fe-Cr-C kuri 870℃, aho icyuma cya H13 giherereye ni heza kurushaho aho uturere twa austenite A na (A+M3C+M7C3) duhurira. Ingano ya C ijyanye nayo ni hafi 0.4%. Iyi shusho yanagaragaje ukwiyongera kw'ingano ya C cyangwa Cr kugira ngo wongere ingano ya M7C3, hamwe n'ibyuma bya A2 na D2 bifite ubushobozi bwo kwangirika cyane kugira ngo ugereranye. Ni ngombwa kandi kugumana ingano nto ya C kugira ngo ingingo ya Ms y'icyuma ifate urugero rw'ubushyuhe buri hejuru (icyuma cya Ms cya H13 gikunze kuvugwa ko ari 340℃), kugira ngo icyuma kibashe kuzimwa kugeza ku bushyuhe bw'icyumba. Shaka imiterere ya alloy C igizwe ahanini na martensite hamwe n'ingano nto ya A isigaye hamwe n'ikwirakwizwa ry'ibisigaye, kandi ubone imiterere ya martensite ishyushye nyuma yo gushyushya. Irinde guhindura austenite nyinshi yagumanye ku bushyuhe bw'akazi kugira ngo bigira ingaruka ku mikorere cyangwa guhinduka kw'igikoresho. Utu duce duto twa austenite twagumanye tugomba guhinduka burundu mu buryo bubiri cyangwa butatu bwo gushyushya nyuma yo kuzimya. Aha ngaha, biragaragara ko imiterere ya martensite iboneka nyuma yo kuzimya icyuma cya H13 ari lath M + ingano nto ya flake M + ingano nto ya A isigaye. Karubide nziza cyane za alloy zashyizwe kuri lath M nyuma yo kuzimya. Intiti zo mu gihugu nazo zakoze akazi kamwe.
