zofunika

M42 high speed steel ndi cobalt molybdenum zida zitsulo, kuwonjezera 8% cobalt zikutanthauza kuti M42 amapereka wapamwamba wofiira kuuma poyerekeza ndi M2. Kuphatikizika kwa M42 kumapangitsa kuti pakhale kulimba kwabwino komanso kuuma ndipo kutha kugwiritsidwa ntchito kwambiri pamitundu yonse ya zida zodulira, zomwe nthawi zambiri zimagwiritsidwa ntchito popanga zida zamakina ndi ma alloys apamwamba kwambiri omwe amavuta makina. M42 imawonetsa kukana kovala bwino chifukwa cha kuuma kwa kutentha kwambiri (68 mpaka 70 HRC), ndipo kuchuluka kwa cobalt kumapangitsa kuuma kotentha. Momwemonso, m'mphepete mwa zida zopangidwa kuchokera ku M42 zitsulo zothamanga kwambiri zimakhala zolimba komanso zolimba pantchito yolemetsa komanso yodula kwambiri.


Mapulogalamu:

Zoyenera kupanga zida zosiyanasiyana zodulira zolimba zosavala, zosagwira kukhudzidwa. Kukhomerera kwapamwamba kufa, wononga kufa, kulimba ndi mawonekedwe ovuta a nkhonya, ndi zina zambiri. Makampani opanga zida zopukutira: scraper, mpeni wa serrated, mipeni yachitsulo, zobowola, ndi zina zambiri.


Makampani Opanga: kutaya ufa.


Bizinesi ya screw: mutu kupanga nkhungu, monga mano, nkhonya

MALANGIZO OTHANDIZA KUTENTHA KUTI: KUVUTA

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


ZOPHUNZITSA ZAIDWI

· Kuchulukitsitsa: 0.282 lb / in3 (7806 kg / m3)

· Mphamvu Yeniyeni: 7.81

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

· Machinability: 35-40% ya 1% mpweya chitsulo


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.
