W6Mo5Cr4V2 (M2) otentha adagulung'undisa zitsulo zozungulira

M2 ndi molybdenum mndandanda mkulu-liwiro zitsulo, ali ubwino waing'ono carbide inhomogeneity ndi kulimba mkulu. Easy kutenthedwa, ayenera mosamalitsa kulamulira quenching Kutentha kutentha, ndi okhwima chitetezo kutentha mankhwala. Chifukwa cha kuuma kwake ndi wearability, ntchito kupanga kudula zovuta kwambiri kudula zida zida. Chitsulo chothamanga kwambiri cha M2 chokhala ndi mawonekedwe a carbide ndichokulirapo, chifukwa chake chitetezo chokhazikika pakuchiza kutentha ndichoyenera kugwedezeka kwa nkhungu ndi katundu wodabwitsa.

SAE M2 Tool Steel Material Mechanical Properties

Kuuma, Rockwell C (kupsa mtima pa 621 ° C, kuzimitsidwa pa 1204 ° C): 62 HRC.

Kuuma, Rockwell C (kutsekedwa pa 1204 ° C) ): 65 HRC

Zopangidwa ndi M2 HSS Steel zitsulo

Poyamba, Pre-Kutentha kwa 650-750 ℃，Kenako kutentha kwa kutentha kwachinyengo. Zilowerereni pa 1204 ° C, onetsetsani kutentha kwambiri. Kenako yambani kunyengedwa, kutentha kwanyengo sikutsika kuposa 950 ℃. Pambuyo pokonza, kuziziritsa pang'onopang'ono.

Chithandizo cha Kutentha kwa SAE M2 Steel

• M2 HSS Zitsulo Annealing

Poyamba, Pang'onopang'ono kutentha kwa 871 ℃, ndiye pang'onopang'ono Kuzizira mpaka 538 ℃ (1000 ℉) mu ng'anjo yochizira kutentha. Ndiye kuziziritsa mu mpweya. Pambuyo pa kuuma kwa HBS: 255 Max.

• Chida cha M2 Kulimbitsa Zitsulo

Chitsulo cha M2 chokhala ndi kuuma kwambiri ndipo chiyenera kuumitsidwa ndi kuzizira mumpweya wokhazikika. Kugwiritsa ntchito madzi osambira amchere kapena ng'anjo yoyendetsedwa ndi mpweya ndikofunikira kuti muchepetse kutenthedwa, ndipo ngati palibe, kuuma kwa paketi mu phula lomwe lagwiritsidwa ntchito kumaperekedwa.
