Cold Works D2 chida chitsulo ndi mkulu carbon, mkulu chromium chida chitsulo (12% chrome) ndi mkulu kwambiri kukana kuvala katundu, kutentha mankhwala angathe 60-62 Rc. Chitsulo cha D2 sichimva kuvala kwambiri koma osati cholimba ngati zitsulo zotsika. Chitsulo cha chida cha D2 chimawumitsa mumlengalenga ndikuyenda pang'ono ndipo chimapereka kukana kwa dzimbiri chikapukutidwa. Kuchuluka kwa chromium kumapangitsa kuti ikhale yolimba yolimbana ndi dzimbiri mumkhalidwe wowuma. Makina a D2 amakhudzidwa kwambiri ndi chithandizo cha kutentha. Chitsulo cha D2 chimapezeka muzozungulira zopanda carb, ma flats, ndi mabwalo, komanso pansi pazitsulo ndi ndodo yobowola.

1.2379 Kupanga Zitsulo

Kutenthetsa popanga chitsulo cha AISI D2 kuyenera kuchitika pang'onopang'ono komanso mofanana. Zilowerereni pa 1850 ° -1950 ° F ndi kutenthetsanso nthawi zonse ngati kuli kofunikira, kuyimitsa ntchito pamene kutentha kumatsika pansi pa 1700 ° F (926 ° C). Pambuyo popanga zitsulo za D2, kuziziritsa pang'onopang'ono mu laimu, mica, phulusa louma kapena ng'anjo. Chitsulo cha D2 chiyenera kutsekedwa nthawi zonse pambuyo popanga.


Kusamalira

Pambuyo potenthetsa bwino, kutentha mpaka 1800 ° -1850 ° F. Igwireni pa kutentha kowumitsa mpaka itatenthedwa kwathunthu ndi mofanana.


Kuyimitsa

Zida zachitsulo za DIN 1.2379 ndi chitsulo chowumitsa mpweya ndipo zimakulitsa kuuma pakuzizirira mumpweya wokhazikika. Kuti mupewe kukulitsa komanso kupewa kutulutsa mpweya pamwamba, mpweya woyendetsedwa bwino kapena ng'anjo za vacuum zimalimbikitsidwa. Zigawo ziyenera kuloledwa kuziziritsa mpaka 150F, kapena pomwe zitha kugwiridwa m'manja, kenako kupsa mtima nthawi yomweyo.


Kutentha

Kutentha kotentha pazitsulo za 1.2379 kungakhale kosiyana malinga ndi kuuma komwe kumafunidwa. Zitsulo za 1.2379 zimatha kutenthedwa pa 204 ° C (400 ° F) kuti mukwaniritse kuuma kwa Rockwell C kwa 61 ndi 537 ° C (1000 ° F) kwa kuuma kwa Rockwell C kwa 54.
