Description:

Nickel otentha ntchito chida chitsulo ndi hardability wabwino. Kulimba kwa yunifolomu pa gawo komanso pamiyeso yayikulu. Kukaniza pansi pazowonjezera zamphamvu. Mphamvu zabwino kwambiri komanso kulimba. Kukana kwabwino kwa kutentha ndi kukhazikika kwa dimensional. Zida zitha kukhala madzi kapena mpweya utakhazikika.

Mapulogalamu:

Zida zopangira, zimafa zamitundu yonse, mawonekedwe ndi makulidwe, zida zowotcha komanso zosindikizira zachitsulo ndi zitsulo. Zinkhungu, mabushings, oboola etc.

Soft Annealing:

Kutenthetsa mpaka 650-700 ° C, kuziziritsa pang'onopang'ono mu ng'anjo. Izi zitulutsa kulimba kwa Brinell kopitilira 248.

Kuchepetsa Kupsinjika:

Kupsinjika kochotsa kupsinjika kwa makina kuyenera kuchitidwa ndi kutentha mpaka 650 ° C, kugwira kwa ola limodzi pakutentha, ndikutsatiridwa ndi kuziziritsa kwa mpweya. Opaleshoniyi imachitidwa kuti achepetse kupotoza panthawi ya chithandizo cha kutentha.

Kuwumitsa:

Mafuta: Imitsani kutentha kwa 830-870 ° C ndikutsatiridwa ndi kuzimitsa mafuta. Kuuma pambuyo kuzimitsa ndi 58 HRC.

Mpweya: Kuumitsa kutentha kwa 830-900 ° C kotsatiridwa ndi kuzimitsa mpweya. Kuuma pambuyo kuzimitsa ndi 56 HRC. 

Kutentha:

Kutentha kotentha: Onani zomwe zili pansipa.
