zofunika
D2 Tool Steel ndi chitsulo chosunthika cha carbon high-chromium, high-chromium, air-hardibility chitsulo chomwe chimadziwika ndi kuuma kwambiri komwe kungatheke komanso ma carbides ambiri, akulu, okhala ndi chromium mu microstructure. Ma carbides awa amapereka kukana kwabwino kuvala kuchokera pakulumikizana ndi zitsulo zina ndi zinthu zonyezimira. Ngakhale zitsulo zina zolimba kwambiri kapena kukana kuvala bwino zilipo, D2 imapereka kuphatikiza kothandiza kwa kukana kuvala ndi kulimba, magwiridwe antchito, mtengo, ndi mitundu yosiyanasiyana yazogulitsa. Imapezekanso ngati chinthu cha Electro-Slag-Remelted (ESR). Njira yotsitsimutsa imapereka kusinthika kwamankhwala, kuwongolera kukula kwa carbide, ndikusintha komwe kumakhudzana ndi makina ndi kutopa.

KUCHITAPO: Mapiringa, nkhonya, amafera kutsekedwa, kupanga, kudula, ndi kugudubuza ulusi, mipeni yometa, mipeni yopangira chakudya, ndi geji.

MAVUTO

Kutentha Kwambiri:

Ac1: 1449 ° F (788 ℃))

Ac3: 1553 ° F (845 ℃))

AR1: 1418 ° F (769 ℃))

AR3: 1373 ° F (744 ℃))

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 1150-1250 ° F (621-677 ° C) mofanana, ndiye kutentha kwa 1400-1450 ° F (760-788 ° C). Pazida zodziwika bwino, gwiritsani ntchito kutentha kwachiwiri kokha ngati chithandizo chotenthetsera chimodzi.

Austenitizing (Kutentha Kwambiri): Kutenthetsa pang'onopang'ono kuchokera ku preheat. Ng'anjo kapena Mchere: 1850-1875 ° F (1010-1024 ° C).

Kuzimitsa: Mpweya kapena mpweya woponderezedwa mpaka 150-125ºF (66-51ºC). Kukula mpaka mainchesi 4 (101.6 mm) mu makulidwe kumadutsa mpweya utakhazikika kuchokera ku 1575ºF (857ºC). Kukula mpaka mainchesi 6 (152.4 mm) mu makulidwe kumadutsa mpweya utakhazikika kuchokera ku 1625ºF (885ºC).

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. Nthawi zambiri kutentha kumakhala 25.4 mpaka 2ºF (350 mpaka 400ºC).

Kuti muzitha kuvala kwambiri, kupsa mtima pakati pa 300-350 ° F (149-177 ° C) pa kuuma kwa 62-64 HRC. Kuti mukhale ndi malire abwino pakati pa kukana kuvala ndi kulimba, kupsa mtima pakati pa 500-550 ° F (260-288 ° C). Izi zidzatulutsa 58-60 HRC.

Kuti mukhale wolimba kwambiri, kupsya mtima kawiri, maola awiri ndi maola awiri, pa kutentha pamwamba pa 2 ° F (2 ° C). Izi zidzatulutsa kuuma kosakwana 950 HRC.

Kuchepetsa kupsinjika kwamkati m'magawo akuluakulu kuposa mainchesi a 6 (152.4 mm) ndikuwongolera kukhazikika kwa zida zomwe zidzakhale EDM'd pambuyo pa chithandizo cha kutentha, nthawi zowuma za 4 mpaka maola 6 pa kutentha kosachepera 950 ° F (510 ° C). ) amalimbikitsidwa kwambiri.

Annealing: Annealing ayenera kuchitidwa pambuyo ntchito yotentha ndi pamaso anaumitsanso. Kutenthetsa pamlingo wosapitirira 400 ° F pa ola (222 ° C pa ola) mpaka 1600-1650 ° F (871-899 ° C), ndipo sungani kutentha kwa ola limodzi pa inchi (1mm) ya makulidwe apamwamba; 25.4 maola osachepera. Ndiye kuziziritsa pang'onopang'ono ndi ng'anjo pa mlingo wosapitirira 2 ° F pa ola (50 ° C pa ola) mpaka 28 ° F (1000 ° C). Pitirizani kuziziritsa kutentha kozungulira mu ng'anjo kapena mpweya. Zotsatira zake kuuma kuyenera kukhala kopitilira 538 HBW.
