20CrMnTi(H) izinsimbi eziyindilinga ezishisayo ezigoqiwe

izici zensimbi eqinile ye-alloy insimbi, inqubo enhle yokwelapha ukushisa kwe-carburizing kanye nokusebenza kwensimbi ku-≤960 ℃ isakhiwo sokusanhlamvu esihle, esivame ukusetshenziswa ekushiseni ukushisa kwe-carburizing yesikhathi eside, okusanhlamvu akuzange kukhule ukuthambekela okuncane okusalayo kwe-austenite ngemva kokucisha, ngakho-ke, insimbi inamandla aphezulu nokumelana nokugqoka, ukusebenza okuhle kakhulu kokusika, ukusebenza okuyinhloko kanye ne-20CrMnTi ne-20CrNi yensimbi efanayo. Amandla aqinile σ ≥1080MPa, amandla esivuno σ ≥885MPa, ubude δ ≥10%, 45% ukuncipha kokuvuvukala, ukuqina komthelela (ukuqina komthelela) α ≥69J/ cm, ubulukhuni ≤207mm usayizi wesampula ukuya ku-5 HB, 5mm usayizi ongenalutho.

I-GB 20CrMnTi GB/T 3077 Mechanical

Izakhiwo zokukhanda ze-GB 20CrMnTi GB/T 3077 metals zinquma ububanzi bosizo lwento futhi zisungula impilo yesevisi engalindelwa. Izakhiwo zemishini nazo zisetshenziselwa ukusiza ukuhlukanisa nokukhomba izinto ezibonakalayo.

Amapharamitha okusebenza ngokomzimba we-GB 20CrMnTi GB/T 3077 aboniswa ikakhulukazi ukuminyana, isilinganiso se-poisson, ukuhanjiswa kwe-thermal, umthamo we-thermal othize, i-coefficient yokunwetshwa kwe-thermal, i-modulus yokunwebeka, inani lokumelana nogesi, njll.

Ukwelashwa Ukushisa Okuhlobene

• Ukufakwa kwensimbi engu-20CrMnTi Alloy Gearing

Kushisisa kancane ku-790-810 ℃ futhi uvumele izikhathi ezanele, vumela insimbi ukuthi ifudunyezwe kahle, Bese upholisa kancane esithandweni. Izindlela ezihlukene zokudonsa zizothola ubulukhuni obuhlukile.Insimbi yokuGearing engu-20CrMnTi izothola Ukuqina MAX 248 HB (ukuqina kweBrinell).

• Ukucisha kanye nezinga lokushisa lensimbi engu-20CrMnTi giya

Ishisisa kancane ukuya ku-788°C, Bese ifaka esithandweni sokugeza usawoti gcina 1191 ℃kuya ku-1204 ℃。ukucisha ngamafutha thola ubulukhuni obungu-60 kuya ku-66 Hrc. Ukushisa okuphezulu kokushisa: 650-700 ℃, kupholile emoyeni, thola ubulukhuni 22 kuya ku-30HRC. Izinga lokushisa eliphansi: 150-200 ℃, Cool  ku-ari, thola ubulukhuni obungu-61-66HRC.

• Umsebenzi oshisayo nomsebenzi obandayo we-20CrMnTi Alloy Gearing steel

Insimbi ye-GB 20CrMnTi ingashisa kusetshenzwe ku-205 kuya ku-538°C, i-20CrMnTi Bearing/Insimbi yokugiya ingabanda kusetshenziswa amasu avamile ezimeni ezishubile noma ezijwayelekile.
