718 isikhuntainsimbi 718 insimbi yokubumba ipulasitiki ekhiqizwa yiSweden I-ASSAB inezakhiwo zemishini, i-machinability, nobuchwepheshe obulula bokucubungula, ngakho-ke isetshenziswa kabanzi ekucubunguleni isikhunta kanye nezimboni zokukhiqiza.Ngaphezu kwalokho, i-718 die steel iye yaqiniswa ngaphambili yaba lukhuni be-41~47HRC ngemva kokushiya imboni ngenqubo ekhethekile yokukhiqiza, enganciphisa izixhumanisi zokwelashwa kokushisa kwamanye amaphrojekthi futhi ithuthukise izinzuzo zezomnotho.

I-Henglei 718 die steel, i-3Cr2NiMo yezwe lethu iyizinga lensimbi elithuthukisiwe ukusuka 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 kwamabanga ensimbi ajwayelekile aseShayina ashiwo ngenhla, amamaki ensimbi avelayo njengamanje emakethe yensimbi yokubumba ezweni lami angu-P20+Ni.I-Sweden's 718, 718H (ASSAB), PX5\PX4 (Japan Datong Special Steel), GS-711, GS-738, GS-312, GS-318 (Germany Thyssen), Austria's M238 ECOPLUS (Bai Lu Company), CS718 (China I-Great Wall Special Steel), i-SWP20 (i-Shanghai No. 5 Steel Company), njll., ngakho-ke ngaphezu kokungasetshenziselwa izingxenye zesikhunta sepulasitiki ezinezidingo zokumelana nokugqwala, okwamanje iyibanga lensimbi elijwayelekile lesikhunta sepulasitiki esisetshenziswa kabanzi. insimbi.Kuvame ukubizwa ngokuthi "insimbi yensimbi yepulasitiki", futhi amamaki ensimbi amasha asanda kuthuthukiswa ngokuvamile ayisebenzisa njengesiqhathaniso esivamile.

Isimo sefekthri: ASSAB 718 HB: 290-310

Isimo sokudiliva: Insimbi ilethwa isesimweni esishubile.Ngemuva kwesivumelwano sobabili, ukulethwa kungenziwa futhi ngaphandle kokuncishiswa.

I-718 steel iyinsimbi yesibuko yepulasitiki ye-ASSAB yaseSweden esenziwe lukhuni ngaphambili.Insimbi iqiniswe ngaphambili, inezinto ezifanayo, ukuhlanzeka okuphezulu, ukusebenza kokupholisha nokusebenza kokuqoshwa kwesithombe.Iphinde ibe nokuqina okuphezulu, ukusebenza kahle kokucutshungulwa kukagesi kanye nokusebenza kokucubungula kwe-dermatoglyph.Insimbi eqiniswe ngaphambili ingasetshenziswa futhi kumgodi wokufa ngaphandle kokucisha, futhi i-flange ingaqiniswa ilangabi ukuze kwenyuswe ubulukhuni ku-52HRC.

Insimbi inokusebenziseka okuhle nokumelana nokugqoka, kanye nokusabalalisa ubulukhuni obufanayo.Iphinde ibe nokusebenza okuhle kokupholisha, ubuchwepheshe obulula bokucubungula kanye nentengo emaphakathi, ngakho-ke umthamo mkhulu.
