M42 super high speed chitsulo ndi premium cobalt high speed chitsulo chokhala ndi mankhwala opangidwa kuti aziuma kwambiri komanso kuuma kotentha kwambiri. Zinthu izi zimapangitsa chitsulo kukhala chisankho chabwino kwambiri chopangira zitsulo zolimba kwambiri komanso zowumitsidwa kale, ma alloys olimba kwambiri, komanso makina ovuta, osagwiritsa ntchito ma alloys apamwamba omwe amagwiritsidwa ntchito muzamlengalenga, mafuta, ndi mafakitale opanga magetsi.

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.

KUCHITAPO: Zobowola zokhota, matepi, zodulira mphero, zopangira mphero, zopota, macheka, mipeni, ndi kugudubuza ulusi zimafa.

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.

ZINTHU ZOFUNIKA

Annealing iyenera kuchitidwa mutatha kugwira ntchito yotentha komanso musanalimbikitsenso.

Kutenthetsa pamlingo wosapitirira 400 ° F pa ola (222 ° C pa ola) mpaka 1500-1575 ° F (843-857 ° C), ndipo gwirani ola limodzi pa inchi (1 mm) ya makulidwe, osachepera maola awiri . Ndiye kuziziritsa pang'onopang'ono ndi ng'anjo pa mlingo wosapitirira 25.4 ° F pa ola (2 ° C pa ola) mpaka 50 ° F (28 ° C). Pitirizani kuziziritsa kutentha kozungulira mu ng'anjo kapena mpweya. Zotsatira zake kuuma kuyenera kukhala 1000 HBW kapena kutsika.

KUPANGA

Yatsani kutentha mpaka 1200-1400 ° F (649-760 ° C) ndikufanana. Kenako tenthetsani mwachangu mpaka 2000-2100 ° F (1093-1149 ° C) ndikufanana musanayambe kupanga. Kutenthetsanso ngati kutentha kwa ntchito kugwera pansi pa 1800 ° F (982 ° C). Pambuyo popanga, kuziziritsa pang'onopang'ono mpaka kutentha kozungulira mu ng'anjo kapena kukwiriridwa mu insulating material, kenako anneal monga tafotokozera pamwambapa.
