Description:

Cold ntchito chida zitsulo ndi mkulu dimensional bata pa kutentha mankhwala. Kukana kwakukulu kwa kusweka. High machinability, kulimba kwapakatikati ndi kukana kuvala. 

Mapulogalamu:

Zida zoyezera, mipeni yamakina yamatabwa, mafakitale a mapepala ndi zitsulo, masamba ometa ozizira ozizira, zida zodulira ulusi.

Soft Annealing:

Kutenthetsa mpaka 690-720 ° C, kuziziritsa pang'onopang'ono mu ng'anjo. Izi zitulutsa kulimba kwa Brinell kopitilira 229.

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:

Limbikitsani kutentha kwa 790-820 ° C ndikutsatiridwa ndi mafuta osamba kapena ofunda (180-220 ° C) kuzimitsa. Kuuma pambuyo kuzimitsa ndi 63-65 HRC.
