Isikhunta esingu-718Insimbi yepulasitiki engu-718 ekhiqizwe yiSweden ASSAB inezakhiwo zemishini, ukusebenza kahle kwemishini, kanye nobuchwepheshe bokucubungula obulula, ngakho-ke isetshenziswa kabanzi embonini yokucubungula isikhunta kanye nokukhiqiza. Ngaphezu kwalokho, insimbi engu-718 die iye yaqiniswa kusengaphambili yaba lukhuni obungu-41~47HRC ngemva kokushiya ifektri ngenqubo ekhethekile yokukhiqiza, enganciphisa izixhumanisi zokwelapha ukushisa kwamanye amaphrojekthi futhi ithuthukise izinzuzo zomnotho.

I-Henglei 718 die steel, i-3Cr2NiMo yezwe lethu iyizinga lensimbi elithuthukisiwe kusukela ku-P20 (3Cr2Mo), futhi ikhwalithi yayo ithuthukiswe kakhulu ukuze igcwalise ukushiyeka kwe-P20 die steel futhi ihlangabezane nezikhathi lapho i-P20 die steel ingakwazi ukuhlangabezana nezidingo. Ngaphezu kwamazinga ensimbi ajwayelekile aseShayina ashiwo ngenhla, amazinga ensimbi abonakala njengamanje emakethe yensimbi yesikhunta ezweni lami yi-P20+Ni. I-718 yaseSweden, 718H (ASSAB), PX5\PX4 (Japan Datong Special Steel), GS-711, GS-738, GS-312, GS-318 (Germany Thyssen), i-M238 ECOPLUS (Bai Lu Company) yase-Austria, CS718 (China Great Wall Special Steel), SWP20 (Shanghai No. 5 Steel Company), njll., ngakho-ke ngaphezu kokungasetshenziswa ezingxenyeni zesikhunta zepulasitiki ezinezidingo zokumelana nokugqwala, okwamanje iyizinga lensimbi elijwayelekile lensimbi yesikhunta sepulasitiki esisetshenziswa kabanzi. Ngokuvamile ibizwa ngokuthi “insimbi yepulasitiki yokubumba”, futhi amazinga ensimbi amasha asanda kuthuthukiswa avame ukuyisebenzisa njengokuqhathanisa okuvamile.

Isimo sefektri: ASSAB 718 HB: 290-310

Isimo sokulethwa: Insimbi ilethwa isesimweni sokucwiliswa. Ngemva kwesivumelwano somuntu ngamunye, ukulethwa kungenziwa ngaphandle kokucwiliswa.

Insimbi engu-718 iyinsimbi yepulasitiki eqiniswe ngaphambili yesibuko engangeni asidi eSweden ASSAB. Insimbi iqiniswe kusengaphambili, inezinto ezifanayo, ihlanzekile kakhulu, isebenza kahle ekupholiseni kanye nokusebenza kahle kokuqopha izithombe. Iphinde ibe nokuqina okuphezulu, ukusebenza kahle kokucubungula ugesi kanye nokusebenza kahle kokucubungula i-dermatoglyph. Insimbi eqiniswe kusengaphambili ingasetshenziswa futhi emgodini we-die ngaphandle kokucima, futhi i-flange ingaqiniswa ilangabi ukuze kwandiswe ubunzima bube ngu-52HRC.

Insimbi inamandla okusebenza kahle kanye nokumelana nokuguguleka, kanye nokusatshalaliswa kobulukhuni okufanayo. Iphinde ibe nokusebenza okuhle kokupholisha, ubuchwepheshe bokucubungula obulula kanye nentengo emaphakathi, ngakho-ke umthamo mkhulu.
