D3 Tool Steel ndi chitsulo cha carbon high-chromium, high-chromium, choumitsa mafuta chomwe chimadziwika ndi kuuma kwakukulu komwe kungatheke komanso ma carbides ambiri, akuluakulu, okhala ndi chromium mu microstructure. Ma carbides awa amapereka kukana kwabwino kuvala kuchokera pakulumikizana ndi zitsulo zina ndi zinthu zonyezimira.

D3 imawonetsa kukhazikika kwabwino pakuchiritsa kutentha, kugwira kukula pafupifupi komanso kuuma mpweya, kaboni wambiri, zitsulo zamtundu wa chromium monga D2.


Mapulogalamu:

1.Kupanga kuzizira kumafa ndi nkhonya zomwe zimakhudzidwa ndi katundu wochepa, wochepa mpaka wapakatikati wopanga, ndipo amafuna kukana kuvala kwakukulu.

2. Chitsamba chozizira chodula chodula zitsulo zolimba komanso zowonda

3. Kwa manja obowola, ma geji, kujambula mawaya, ma embossing amafa, mbale za crepe, zojambula zimafa, kuzizira kozizira kumafa ndi zowola.

4. Yoyenera kupanga nkhungu zazikulu, zovuta komanso zolondola zapulasitiki zomwe zimafuna kukana kwakukulu

ZOPHUNZITSA ZAIDWI

· Kuchulukitsitsa: 0.284 lb / in3 (7870 kg / m3)

· Mphamvu Yeniyeni: 7.87

Modulus of Elasticity: 30 x 106 psi (207GPa)

Kukaniza kwa Magetsi: 54.8 uOhm-cm pa 70ºF (21ºC)

· Machinability: 45-50% ya 1% mpweya chitsulo

Kutentha:Kuchepetsa kupotoza ndi kupsinjika mu zida zazikulu kapena zovuta gwiritsani ntchito preheat iwiri. Kutenthetsa pamlingo wosapitirira 400 ° F pa ola (222 ° C pa ola) mpaka 1200-1250 ° F (649-677 ° C) mofanana, ndiye kutentha kwa 1400-1450 ° F (760-788 ° C). Pazida zabwinobwino, gwiritsani ntchito kutentha koyambirira kokha ngati njira imodzi yopangira kutentha.

Kutentha Kwambiri (Kutentha Kwambiri): Kutenthetsa pang'onopang'ono kuchokera ku preheat kufika 1700-1750 ° F (927-954 ° C)


Kuthetsa:Kwa mafuta, kuzimitsa mpaka wakuda, pafupifupi 900 ° F (482 ° C), kenako kuziziritsa mumlengalenga mpaka 150-125 ° F (66-51 ° C).

Kwa gasi wopanikizika, ng'anjoyo iyenera kukhala ndi mphamvu yocheperapo ya 4 mipiringidzo. Kuzimitsa kwa pafupifupi 400 ° F (222 ° C) pamphindi kufika pansi pa 1000 ° F (538 ° C) ndikofunikira kuti mupeze zinthu zomwe mukufuna.


Kutentha:Kupsa mtima mwamsanga pambuyo kuzimitsa. Gwirani kutentha kwa ola limodzi pa inchi (1 mm) ya makulidwe, osachepera maola awiri, kenako mpweya wozizira mpaka kutentha kozungulira.

Kuti muzitha kuvala kwambiri, kupsa mtima pakati pa 300-350 ° F (149-177 ° C) pa kuuma kwa 62-63 HRC. Kuti mukhale ndi malire abwino pakati pa kukana kuvala ndi kulimba, kupsa mtima pakati pa 450-500 ° F (232-260 ° C). Izi zidzatulutsa 58-60 HRC.

Kuchepetsa kupsinjika kwamkati m'magawo akuluakulu kuposa mainchesi 6 (152.4 mm) ndikuwongolera kukhazikika kwa zida zomwe zidzakhale EDM'd pambuyo pa chithandizo cha kutentha, nthawi zothira maola 4 mpaka 6 pa kutentha kotentha zimalimbikitsidwa kwambiri.


Ubwino ::

1.High abrasive resistance ndi katundu wochepa wodabwitsa

2. High kuvala kukana motsutsana abrasive ndi zomatira kuvala

3. Kulimba kwapakatikati

4.Dimensionally stable
