35CrMnSiA inopisa yakakungurutswa simbi pepa

35CrMnSiA isimbi yakaderera-yakakwirira-yakakwirira-yakasimba. Mushure mekurapa kwekupisa, ine yakanaka yakazara mechanicha zvinhu, kusimba kwepamusoro, kusimba kwakakwana, kuomarara, weldability (preheating isati yavekupisa), uye kugadzirisa formability, asi ine yakanaka corrosion resistance uye Low oxidation resistance, inowanzo shandiswa mushure mekudzika kwekushisa kana kuomesa. Yakakwirira-yakasimba inodzima uye yakadzikama simbi yekugadzira. Iyo ine simba repamusoro uye kuoma, kuomarara kwepamusoro, yepakati inotonhora deformation plasticity, uye yakanaka yekucheka kuita. Pane katsika kekushatirisa brittleness, uye transverse impact kuoma kwakashata. The welding performance iri nani, asi kana ukobvu hwakura kupfuura 3mm, hunofanira kutanga huchipisa kusvika 150 ℃, uye kupisa kunodiwa mushure mekunama. Kazhinji inoshandiswa mushure mekupisa.

Chinangwaedit
35CrMnSiA inoshandiswa kugadzira yepakati-kumhanya, inorema-basa, yakakwirira-simba, yakakwirira-yakaomesesa zvikamu uye yakakwirira-yakasimba zvikamu.
Inonyanya kushandiswa kugadzira zvikamu zvakasiyana-siyana zvakakosha zvine mutoro wakakwirira uye kumhanya, zvakadai semagiya, shafts, clutches, sprockets, grinding wheel shafts, bushings, bolts, nuts, nezvimwewo. Inoshandiswawo kugadzira zvidimbu zvisingapfekeki zvine zvishoma. kushanda tembiricha uye chinja mutoro. Welded zvinhu zvakaita se high-pressure blower blades, valve plates nemapombi asingaparadzi.

Tsanangudzo yekurapa kwekupisa uye sangano re metallographic
Zvinotsanangurwa zvekupisa kupisa: (1) Kudzima: yekutanga 950 ℃, yechipiri 890 ℃, kutonhora kwemafuta; kupisa 230 ℃, kutonhora kwemhepo, kutonhora kwemafuta; (2) 880 ℃ inotyisa pa280～310℃.
Mamiriro ekutumira anofanirwa kutsanangurwa muchibvumirano kana yaunzwa nekupisa (normalizing, annealing kana kupisa kwakanyanya) kana pasina kupisa kupisa.

GB/T 11251 35CrMnSiA inopisa yakakungurutswa chimiro chesimbi mahwendefa eGnee simbi anoshandiswa zvakanyanya kugadzira kukurumidza kwepakati, mutoro unorema, simba rakakwirira, kusimba kwepamusoro uye zvikamu zvesimba zvakakwirira. Gnee simbi inoda kuve yako yakavimbika 35CrMnSiA inopisa yakakungurutswa alloy simbi mahwendefa.

Gnee Steel inoshanda neGB/T 11251 35CrMnSiA hot rolled structure steel plates iyo iri pasi peGB/T specification.GB/T 11251 35CrMnSiA inopisa yakakungurutswa chimiro chesimbi mahwendefa ane yakanakisa mechanical zvivakwa uye kushandiswa kwakawanda. Kubatanidza mabhenefiti ari pamusoro anogona kupihwa zvakanyanya zvinoenderana nezvinodiwa nevatengi zvigadzirwa. Uyezve, isu tichapa kucheka, pretreatment, galvanizing, kuyedza, kupisa kupisa masevhisi eGB/T 11251 35CrMnSiA inopisa yakakungurutswa chimiro chesimbi mahwendefa.
