1. Pindani kuti musinthe cholinga cha ndimeyi
H13 chitsulo chamotoimagwiritsidwa ntchito popanga zida zofota zomwe zimakhala ndi katundu wambiri, kutentha kwapang'onopang'ono kumafa, kufota kolondola kumafa;kufa-kuponyedwa kumafa chifukwa cha aluminiyumu, mkuwa ndi ma aloyi awo.

Ndiko kuyambitsa kwa H13 air quench hard work die steel die steel kuchokera ku United States.Katundu ndi ntchito zake ndizofanana ndi zachitsulo cha 4Cr5MoSiV, koma chifukwa cha kuchuluka kwa vanadium, kutentha kwake kwapakati (madigiri 600) ndikwabwino kuposa chitsulo cha 4Cr5MoSiV.Ndizitsulo zoyimira zitsulo zomwe zimagwiritsidwa ntchito mosiyanasiyana muzitsulo zotentha zakufa.
2. Mbali
Chitsulo chosungunuka cha Electroslag, chitsulocho chimakhala cholimba kwambiri komanso kukana kuphulika kwamafuta, chitsulocho chimakhala ndi zinthu zambiri za carbon ndi vanadium, kukana kuvala bwino, kulimba kocheperako, komanso kukana kutentha.Pakutentha kwambiri, imakhala ndi mphamvu komanso kuuma kwamphamvu, kukana kwamphamvu kwambiri komanso kulimba, makina amakina abwino kwambiri komanso kukhazikika kwamphamvu kwapang'onopang'ono.
3. The mankhwala zikuchokera zitsulo
Chitsulo cha H13 ndi C-Cr-Mo-Si-V chitsulo, chomwe chimagwiritsidwa ntchito kwambiri padziko lonse lapansi.Panthawi imodzimodziyo, akatswiri ambiri ochokera m'mayiko osiyanasiyana achita kafukufuku wambiri pa izo ndipo akufufuza kusintha kwa mankhwala.Chitsulo chimagwiritsidwa ntchito kwambiri ndipo chimakhala ndi makhalidwe abwino kwambiri, makamaka omwe amatsimikiziridwa ndi mankhwala achitsulo.Inde, zinthu zonyansa muzitsulo ziyenera kuchepetsedwa.Deta ina imasonyeza kuti pamene Rm ndi 1550MPa, sulfure zomwe zili muzinthuzo zimachepetsedwa kuchoka pa 0.005% kufika pa 0.003%, zomwe zidzawonjezera mphamvu zowonongeka ndi pafupifupi 13J.Mwachiwonekere, muyezo wa NADCA 207-2003 umanena kuti sulufule yazitsulo zamtengo wapatali za H13 ziyenera kukhala zosakwana 0.005%, pamene sulfure yapamwamba iyenera kukhala yosachepera 0.003%S ndi 0.015% P.Kupanga kwachitsulo cha H13 kumawunikidwa pansipa.

Chitsulo cha H13 chokhala ndi 5% Cr chiyenera kukhala cholimba kwambiri, kotero kuti C yake iyenera kusungidwa pamlingo womwe umapanga kachigawo kakang'ono ka alloy C.Woodyatt ndi Krauss adanena kuti pa chithunzi cha Fe-Cr-C ternary phase pa 870 ℃, malo a zitsulo za H13 ali bwino pamagulu a austenite A ndi (A + M3C + M7C3) zigawo zitatu.Zogwirizana ndi C zili pafupifupi 0.4%.Chiwerengerocho chinawonetsanso kuwonjezeka kwa kuchuluka kwa C kapena Cr kuti awonjezere kuchuluka kwa M7C3, ndi zitsulo za A2 ndi D2 zokhala ndi kukana kwapamwamba kwambiri poyerekeza.M'pofunikanso kukhalabe ndi otsika C okhutira kupanga Ms mfundo ya zitsulo kutenga mlingo wapamwamba kwambiri kutentha (Ms wa H13 zitsulo zambiri amatchedwa 340 ℃), kotero kuti chitsulo akhoza kuzimitsidwa ndi kutentha firiji.Pezani aloyi C kaphatikizidwe kaphatikizidwe kamene kamapangidwa ndi martensite kuphatikiza pang'ono A yotsalira ndi yotsalira yogawa yunifolomu, ndikupeza mawonekedwe ofananirako a martensite pambuyo potentha.Pewani kusintha kwambiri kusungidwa kwa austenite pa kutentha kwa ntchito kuti kukhudze magwiridwe antchito kapena mapindidwe a workpiece.Izi zing'onozing'ono za austenite zosungidwa ziyenera kusinthidwa kwathunthu mu njira ziwiri kapena zitatu zotentha pambuyo pozimitsa.Mwa njira, zikusonyezedwa apa kuti dongosolo martensite analandira pambuyo kuzimitsa H13 zitsulo ndi lath M + pang'ono flake M + pang'ono yotsalira A.
