20CrMnTi (H) intsimbi eshushu eqengqelekayo imivalo engqukuva

iimpawu zentsimbi eqinile ingxubevange isixhobo intsimbi, inkqubo carburizing elungileyo unyango ubushushu kunye nokusebenza kwentsimbi kwi ≤960 ℃ isakhiwo okuziinkozo ecolekileyo, eqhele ukusetyenziswa ixesha elide ukufudumeza carburizing lobushushu, iinkozo wakhula akukho utyekelo encinane intsalela austenite emva kokucinywa, ke ngoko, intsimbi inamandla amakhulu kunye nokumelana nokugqoka, ukusebenza kakuhle kokusika, ukusebenza okuphambili kunye ne-20CrMnTi kunye ne-20CrNi yensimbi efanayo. Amandla e-tensile σ ≥1080MPa, amandla emveliso σ ≥885MPa, ubude δ ≥10%, 45% ukuncipha kokudumba, ukuqina kwempembelelo (ukuqina kwempembelelo) α ≥69J / cm, ubulukhuni ≤207mm ubukhulu besampulu 5HB, 5mm ubukhulu besampulu.

I-GB 20CrMnTi GB/T 3077 Mechanical

Iimpawu zomatshini ze-GB 20CrMnTi GB/T 3077 methali zimisela uluhlu lokusebenziseka kwezinto kunye nokuseka ubomi benkonzo obunokulindelwa. Iimpawu zoomatshini zikwasetyenziselwa ukunceda ukwahlula nokuchonga imathiriyeli.

• Ukufakwa kwentsimbi ye-20CrMnTi Alloy Gearing

Ukufudumala kancinane ukuya kwi-790-810 ℃ kwaye uvumele amaxesha aneleyo, vumela intsimbi ukuba ifudunyezwe ngokucokisekileyo, Emva koko upholise ngokukhawuleza kwiziko. Iindlela ezahlukeneyo zokufunxa ziya kufumana ubunzima obahlukeneyo.Intsimbi yokuGeya ye-20CrMnTi iya kufumana Ubulukhuni MAX 248 HB (ubulukhuni beBrinell).

• Ukucima kunye nobushushu bentsimbi ye-20CrMnTi

Ifudunyezwe kancinane ukuya ku-788°C, Emva koko ifake kwiziko lokuhlambela ityuwa gcina i-1191 ℃ukuya ku-1204 ℃。ukucinywa nge-oyile ufumane 60 ukuya ku-66 Hrc ubulukhuni. Ubushushu obuphezulu bobushushu: 650-700 ℃, pholile emoyeni, fumana ubulukhuni 22 ukuya 30HRC. Ubushushu obuphantsi: 150-200 ℃, Cool kwi-ari, fumana 61-66HRC ubulukhuni.

• Umsebenzi oshushu kunye nomsebenzi obandayo we-20CrMnTi Alloy Gearing steel
