1. Goqa ukuze uhlele inhloso yalesi sigaba
Insimbi ye-H13 dieisetshenziselwa ukukhiqiza ama-dies okwakha anomthwalo omkhulu, ama-dies okukhipha ashisayo, ama-dies okwakha ngokunemba; ama-dies okukhipha i-die e-aluminium, ithusi kanye nama-alloy awo.

Kuwukwethulwa kwensimbi ye-H13 air quench hardening hot work die evela e-United States. Izakhiwo zayo kanye nokusetshenziswa kwayo kufana kakhulu naleyo yensimbi ye-4Cr5MoSiV, kodwa ngenxa yokuqukethwe kwayo okuphezulu kwe-vanadium, ukusebenza kwayo okuphakathi (ama-degrees angu-600) kungcono kunensimbi ye-4Cr5MoSiV. Kuyizinga lensimbi elimele elinokusetshenziswa okubanzi ensimbini ye-hot work die.
2. Izici
Insimbi encibilikisiwe nge-electroslag, insimbi inokuqina okuphezulu kanye nokumelana nokuqhekeka kokushisa, insimbi iqukethe okuqukethwe okuphezulu kwekhabhoni ne-vanadium, ukumelana okuhle nokuguguleka, ukuqina okubuthakathaka, kanye nokumelana okuhle nokushisa. Emazingeni okushisa aphezulu, inamandla nokuqina okungcono, ukumelana okuphezulu nokuguguleka, izakhiwo ezinhle kakhulu zemishini kanye nokuqina okuphezulu kokumelana nokushisa.
3. Ukwakheka kwamakhemikhali ensimbi
Insimbi ye-H13 iyinsimbi ye-C-Cr-Mo-Si-V, esetshenziswa kabanzi emhlabeni. Ngesikhathi esifanayo, izazi eziningi ezivela emazweni ahlukahlukene zenze ucwaningo olunzulu ngayo futhi zihlola ukuthuthukiswa kokwakheka kwamakhemikhali. Insimbi isetshenziswa kabanzi futhi inezici ezinhle kakhulu, ikakhulukazi ezinqunywa ukwakheka kwamakhemikhali kwensimbi. Yiqiniso, izinto ezingcolile ensimbini kumele zincishiswe. Olunye ulwazi lubonisa ukuthi uma i-Rm ingu-1550MPa, okuqukethwe kwesulfure kwezinto kuncishiswa kusuka ku-0.005% kuya ku-0.003%, okuzokhulisa ukuqina komthelela cishe ngo-13J. Ngokusobala, indinganiso ye-NADCA 207-2003 ibeka ukuthi okuqukethwe kwesulfure kwensimbi ye-premium H13 kufanele kube ngaphansi kuka-0.005%, kuyilapho okuqukethwe kwesulfure kwe-superior kufanele kube ngaphansi kuka-0.003%S kanye no-0.015%P. Ukwakheka kwensimbi ye-H13 kuhlaziywe ngezansi.

I-Carbon: I-American AISI H13, i-UNS T20813, i-ASTM (inguqulo yakamuva) i-H13 kanye ne-FED QQ-T-570 H13 steel zinokuqukethwe kwekhabhoni okungu-(0.32~0.45)%, okuyikho okuqukethwe kwekhabhoni okuningi kunawo wonke.Izinsimbi ze-H13. Ububanzi. Okuqukethwe kwekhabhoni kwe-X40CrMoV5-1 yaseJalimane kanye no-1.2344 kungu-(0.37~0.43)%, kanti ububanzi bokuqukethwe kwekhabhoni buncane. Ku-DIN17350 yesiJalimane, okuqukethwe kwekhabhoni kwe-X38CrMoV5-1 kungu-(0.36~0.42). Okuqukethwe kwekhabhoni kwe-SKD 61 eJapane kungu-(0.32~0.42). Okuqukethwe kwekhabhoni kwe-4Cr5MoSiV1 kanye ne-SM 4Cr5MoSiV1 ku-GB/T 1299 yezwe lami kanye ne-YB/T 094 kungu-(0.32~0.42)% kanye no-(0.32~0.45)%, okufana ne-SKD61 kanye ne-AISI H13, ngokulandelana. Ngokukhethekile, kufanele kuphawulwe ukuthi okuqukethwe kwekhabhoni kwensimbi ye-H13 kumazinga e-North American Die Casting Association NADCA 207-90, 207-97 kanye ne-207-2003 kuchazwe njengo (0.37~0.42)%.

Insimbi ye-H13 equkethe i-5% Cr kufanele ibe nokuqina okuphezulu, ngakho-ke okuqukethwe kwayo kwe-C kufanele kugcinwe ezingeni elakha inani elincane lama-compound e-alloy C. UWoodyatt noKrauss baveze ukuthi kumdwebo wesigaba se-ternary se-Fe-Cr-C ku-870℃, indawo yensimbi ye-H13 ingcono lapho kuhlangana khona izifunda zesigaba sesithathu ze-austenite A kanye ne-(A+M3C+M7C3). Okuqukethwe kwe-C okuhambisanayo cishe ku-0.4%. Lesi sibalo siphinde saphawula ukwanda kwenani le-C noma le-Cr ukwandisa inani le-M7C3, kanye nezinsimbi ze-A2 ne-D2 ezinokumelana okuphezulu kokuguguleka ukuze kuqhathaniswe. Kubalulekile futhi ukugcina okuqukethwe kwe-C okuphansi ukuze wenze iphuzu le-Ms lensimbi lithathe izinga lokushisa eliphakeme (insimbi ye-Ms ye-H13 ngokuvamile ichazwa njengo-340℃), ukuze insimbi ikwazi ukucinywa ekushiseni kwegumbi. Thola isakhiwo se-compound se-alloy C esakhiwe kakhulu yi-martensite kanye nenani elincane le-A esele kanye nokusatshalaliswa okufanayo okusele, bese uthola isakhiwo se-martensite esilinganiselayo ngemva kokushisa. Gwema ukuguqula i-austenite eningi kakhulu egcinwe ekushiseni kokusebenza ukuze uthinte ukusebenza noma ukuguqulwa komsebenzi. Lawa manani amancane e-austenite egciniwe kufanele aguqulwe ngokuphelele ezinqubweni ezimbili noma ezintathu zokushisa ngemva kokucima. Ngendlela, kuboniswe lapha ukuthi isakhiwo se-martensite esitholwe ngemva kokucima insimbi ye-H13 yi-lath M + inani elincane le-flake M + inani elincane le-A elisele. Ama-carbide e-alloy amahle kakhulu awela ku-lath M ngemva kokushisa. Izazi zasekhaya nazo zenze umsebenzi othile.
