Zitsulo zothamanga kwambiri za molybdenum ndi tungsten zothamanga kwambiri ndi mitundu iwiri yazitsulo zothamanga kwambiri. Zitsulo zothamanga kwambiri za Molybdenum, zomwe zimadziwikanso kuti zitsulo zamagulu M, zimakhala ndi mtengo wocheperako. Mitundu yachitsulo ya Molybdenum M1 mpaka M10 ili ndi tungsten pomwe cobalt sapezeka mumtundu wa M6. Cobalt kulibe konse mu mitundu iyi ya zitsulo zothamanga kwambiri za molybdenum.

Chitsulo chachitsulo cha M42, mtundu wa chitsulo cha molybdenum high speed tool, chimakhala ndi kukana kovala bwino komanso kuuma kotentha pamodzi ndi kuuma kwakukulu.


Mapulogalamu:

Chitsulo cha M42 chimagwiritsidwa ntchito kwambiri pazida zamakina ndi ma alloys apamwamba omwe ndi ovuta kupanga. Zida zamakina zimaphatikiza ma chasers, ma broaches, mawonekedwe ndi odula zida, ma hobs, kubowola, odula mphero, mphero ndi matepi.

ZINTHU ZACHIBALE

MALANGIZO OTHANDIZA KUTENTHA KUTI: KUVUTA

MAVUTO
Kutentha Kwambiri:
Ac1: 1560 ° F (849 ℃))


Kutentha: Kutenthetsa pamlingo wosapitirira 400 ° F pa ola (222 ° C pa ola) mpaka 1500-1600 ° F (816-871 ° C), ndikufanana.


Austenitizing (Kutentha Kwambiri): Kutenthetsa mofulumira kuchokera ku preheat.

Ng'anjo: 2150-2175°F (1177-1191°C)

Mchere: 2125-2150°F (1163-1177°C)

Kuti muwonjezere kulimba, gwiritsani ntchito kutentha kochepa kwambiri.

Kuti muwonjezere kutentha kwambiri, gwiritsani ntchito kutentha kwambiri.


Kuthetsa: Mpweya wopanikizika, mafuta ofunda, kapena mchere. Kwa gasi wopanikizidwa, kuthamanga kwachangu kumafika pansi pa 1000 ° F

(538 ° C) ndikofunikira kuti mupeze zomwe mukufuna. 

Pa mafuta, zimitsani mpaka wakuda, pafupifupi 900 ° F (482 ° C), kenako kuziziritsa mumpweya wabata mpaka 150 -125 ° F (66-51 ° C).

Pakuti mchere anakhalabe pa 1000-1100 ° F (538-593 ° C), mufanane, ndiye ozizira mu mpweya akadali 150 -125 ° F (66-51 ° C).


Kutentha: Kupsa mtima mwamsanga pambuyo kuzimitsa. Kutentha kofananira ndi 950-1050°F (510-566°C). Gwirani pa kutentha kwa 2 hours, kenako mpweya ozizira ndi yozungulira kutentha. Kutentha katatu kumafunika.
