1. Songa ukuze uhlele injongo yale ndima
Intsimbi ye-H13 dieisetyenziselwa ukwenza ii-forging dies ezinomthwalo ophezulu, ii-hot extrusion dies, ii-precision forging dies; ii-die-casting dies ze-aluminium, i-copper kunye nee-alloys zazo.

Kukungeniswa kwe-H13 air quench hardening hot work die steel evela eMelika. Iipropati zayo kunye nokusetyenziswa kwayo ziyafana nezo zentsimbi ye-4Cr5MoSiV, kodwa ngenxa yomxholo wayo ophezulu we-vanadium, ukusebenza kwayo okuphakathi (ii-degrees ezingama-600) kungcono kunentsimbi ye-4Cr5MoSiV. Ludidi lwentsimbi olumeleyo oluneendlela ezahlukeneyo zokusetyenziswa kwintsimbi ye-hot work die.
2. Iimpawu
Intsimbi enyibilikisiweyo yi-electroslag, intsimbi inokuqina okuphezulu kunye nokumelana nokuqhekeka kobushushu, intsimbi iqulethe umxholo ophezulu wekhabhoni kunye ne-vanadium, ukumelana nokuguguleka okuhle, ukuqina okubuthathaka, kunye nokumelana nobushushu okuhle. Kumaqondo obushushu aphezulu, inamandla kunye nobunzima obungcono, ukumelana nokuguguleka okuphezulu, iipropati ezibalaseleyo zoomatshini kunye nokuzinza okuphezulu kokumelana nokufutha.
3. Ukwakheka kweekhemikhali zentsimbi
Intsimbi ye-H13 yintsimbi ye-C-Cr-Mo-Si-V, esetyenziswa kakhulu kwihlabathi liphela. Kwangaxeshanye, izazi ezininzi ezivela kumazwe ahlukeneyo zenze uphando olunzulu ngayo kwaye zihlola ukuphuculwa kokwakheka kweekhemikhali. Intsimbi isetyenziswa kakhulu kwaye ineempawu ezibalaseleyo, ikakhulu ezimiselwa bukwakheka kweekhemikhali zentsimbi. Kakade ke, izinto ezingcolileyo kwintsimbi kufuneka zincitshiswe. Olunye ulwazi lubonisa ukuba xa i-Rm iyi-1550MPa, umxholo wesalfure wezinto uncitshiswa ukusuka kwi-0.005% ukuya kwi-0.003%, nto leyo eya kunyusa ukuqina kwempembelelo malunga ne-13J. Ngokucacileyo, umgangatho we-NADCA 207-2003 umisela ukuba umxholo wesalfure wentsimbi ye-premium H13 kufuneka ube ngaphantsi kwe-0.005%, ngelixa umxholo wesalfure we-superior kufuneka ube ngaphantsi kwe-0.003%S kunye ne-0.015%P. Ukwakheka kwentsimbi ye-H13 kuhlalutywa ngezantsi.

Ikhabhoni: I-American AISI H13, i-UNS T20813, i-ASTM (uhlobo lwamva nje) intsimbi ye-H13 kunye ne-FED QQ-T-570 H13 zinomxholo wekhabhoni we-(0.32~0.45)%, oyena mxholo wekhabhoni uphezulu kunayo yonke.Iintsimbi ze-H13. Ububanzi. Umxholo wekhabhoni we-X40CrMoV5-1 yaseJamani kunye ne-1.2344 yi (0.37~0.43)%, kwaye uluhlu lomxholo wekhabhoni luncinci. Kwi-DIN17350 yaseJamani, umxholo wekhabhoni we-X38CrMoV5-1 yi (0.36~0.42). Umxholo wekhabhoni we-SKD 61 eJapan yi (0.32~0.42). Umxholo wekhabhoni we-4Cr5MoSiV1 kunye ne-SM 4Cr5MoSiV1 kwi-GB/T 1299 yelizwe lam kunye ne-YB/T 094 yi (0.32~0.42)% kunye ne (0.32~0.45)%, ezifanayo ne-SKD61 kunye ne-AISI H13, ngokwahlukeneyo. Ngokukodwa, kufuneka kuchazwe ukuba umxholo wekhabhoni wentsimbi ye-H13 kwimigangatho yeNorth American Die Casting Association NADCA 207-90, 207-97 kunye ne-207-2003 ichazwe njenge (0.37~0.42)%.

Intsimbi ye-H13 equlethe i-5% Cr kufuneka ibe nokuqina okuphezulu, ngoko ke umxholo wayo we-C kufuneka ugcinwe kwinqanaba elenza inani elincinci leekhompawundi ze-alloy C. UWoodyatt noKrauss babonise ukuba kwidayagram yesigaba se-ternary ye-Fe-Cr-C kwi-870℃, indawo yentsimbi ye-H13 ingcono kwindawo yokudibana kwemimandla yesigaba sesithathu se-austenite A kunye ne-(A+M3C+M7C3). Umxholo we-C ohambelanayo umalunga ne-0.4%. Lo mfanekiso ukwaphawule ukunyuka kobungakanani be-C okanye be-Cr ukwandisa ubungakanani be-M7C3, kunye neentsimbi ze-A2 kunye ne-D2 ezinokumelana nokuguguleka okuphezulu ukuze kuthelekiswe. Kubalulekile kwakhona ukugcina umxholo we-C ophantsi ukuze wenze i-Ms point yentsimbi ithathe inqanaba lobushushu eliphezulu (intsimbi ye-Ms ye-H13 ngokubanzi ichazwa njenge-340℃), ukuze intsimbi ikwazi ukucinywa kubushushu begumbi. Fumana isakhiwo sekhompawundi ye-alloy C esenziwe ikakhulu yi-martensite kunye nenani elincinci le-A eseleyo kunye nokusasazwa kwe-uniform eseleyo, kwaye ufumane isakhiwo se-martensite efudumeleyo efanayo emva kokufudumala. Kuphephe ukuguqula i-austenite eninzi egciniweyo kubushushu bokusebenza ukuze ichaphazele ukusebenza okanye ukuguqulwa komsebenzi. La manani amancinci e-austenite egciniweyo kufuneka aguqulwe ngokupheleleyo kwiinkqubo ezimbini okanye ezintathu zokuthambisa emva kokucima. Ngendlela, kuchazwe apha ukuba isakhiwo se-martensite esifunyenwe emva kokucima intsimbi ye-H13 yi-lath M + inani elincinci le-flake M + inani elincinci le-A eseleyo. Ii-carbides ezintle kakhulu ze-alloy ezifakwe kwi-lath M emva kokucima. Izazinzulu zasekhaya nazo zenze umsebenzi othile.
