DIN 30CrNiMo8 ibyuma

30CrNiMO8 ivugwa nka zeru eshatu zeru chromium nikel molybdenum zeru umunani, urukurikirane rwitsinda ryibyuma: CrNiMo, code ya digitale: 1.6580, 30CrNiMo8 mubidage DIN isanzwe yazimye kandi ifite ubushyuhe, bihwanye nu Bushinwa 30Cr2Ni2Mo
Kumenyekanisha ibicuruzwa

DIN 30CrNiMo8 ibyuma nicyuma kivanze cyakozwe muburyo bwambere mubicuruzwa byakozwe.

  • DIN 30CrNiMo8 ibikoresho nicyuma kimwe cyubatswe gifite ubukana buciriritse bwagenewe ibikoresho biremereye, birangwa na elastique nini nimbaraga zirenga 1560 N / mm2 kuri diametero nto. Iyo yoroshye, ubukana bugera kuri max. 248 HRB.
  • Irangwa kandi no kurwanya imitwaro ihinduka n'ingaruka.
  • Ariko, ntabwo aribyiza byo gusudira kandi amaherezo bisaba kongera ubushyuhe.

Gnee ubu ibitse 30CrNiMo8 ibyuma bizenguruka kugirango bihite byoherezwa bifite ireme ryizewe kandi biboneka bya diameter. Bishyushye cyangwa ubushyuhe buvanze uruziga rurahari. Dore bimwe mubisobanuro bya 30CrNiMo8:

1. Gutanga Urwego rwa DIN 30CrNiMo8 Icyuma Cyicyiciro

30CrNiMo8 Uruziga ruzengurutse: diameter 20 ~ 130mm

  • Kubisanzwe

Ubushyuhe: 850-880oC.

  • Gukomera

Harden kuva ku bushyuhe bwa 830-880oC ikurikirwa no kuzimya amavuta.

  • Ubushyuhe

Ubushyuhe bukabije: 540-680oC.

7. Gusaba 30CrNiMo8 Uruziga

Kubintu byatsindagirijwe burundu hamwe nibice binini byambukiranya ibinyabiziga nubukanishi. Kubikorwa byubukungu munsi yingutu zikomeye, ibice bigomba gutegurwa imbaraga nziza cyangwa gukomera.
