20CrMnTi(H) bir wareeg ah oo kulul

sifooyinka birta daawaynta birta qallafsan, habka daaweynta kulaylka carburizing wanaagsan iyo waxqabadka birta at ≤960 ℃ qaab dhismeedka hadhuudh wanaagsan, caadi ahaan loo isticmaalo heerkulka carburizing kulaylka muddada-dheer, hadhuudh koray wax u janjeera in yar austenite haraaga ka dib deminta, Sidaa darteed, birta waxay leedahay xoog sare oo xirto iska caabin ah, waxqabadka goynta aad u fiican, waxqabadka ugu weyn iyo 20CrMnTi iyo 20CrNi birta la mid ah. Xoog xajin σ ≥1080MPa, soo saari xoog σ ≥885MPa, elongation δ ≥10%, 45% dhimista bararka, adkaanta saamaynta (adkeydka saamaynta) α ≥69J / cm, adkaanta ≤207HB, muunad 15mm ilaa 15mm.

GB 20CrMnTi GB /T 3077 Mechanical

Sifooyinka makaanikada ee GB 20CrMnTi GB/T 3077 metals ayaa go'aamiya inta ay le'eg tahay faa'iidada shay waxayna dejiyaan nolosha adeegga ee la fili karo. Qalabka makaanikada ayaa sidoo kale loo isticmaalaa in lagu caawiyo kala soocida iyo aqoonsiga walxaha.

Daaweynta kulaylka La Xiriira

• Burinta 20CrMnTi Alloy Gearing steel

Si tartiib ah u kuleyl ilaa 790-810 ℃ una ogolow waqtiyo ku filan, u ogolow birta in si fiican loo kululeeyo, Kadibna si tartiib ah ugu qabooji foornada. Siyaabaha kala duwan ee wax u dhimista ayaa heli doona qallafsanaan kala duwan. Birta 20CrMnTi Gearing waxay heli doontaa Hardness MAX 248 HB (Brinell hardness).

• Deminta iyo heerkulka 20CrMnTi  Birta Gear

Si tartiib ah u kululee ilaa 788°C,kadibna ku rid foornada qubeyska milixda ku hayso 1191 ℃ ilaa 1204 ℃. Demin saliidda hel 60 ilaa 66 HRc adag Heerkulka sare ee heerkulka: 650-700 ℃, qabow hawo, hel adkaanta 22 ilaa 30HRC. Heerkul hoose: 150-200 ℃, Qabow  in ari, hel adkaanta 61-66HRC.

• Shaqada kulul iyo shaqada qabow ee 20CrMnTi Alloy Gearing steel

GB 20CrMnTi birta waxay noqon kartaa mid kulul oo shaqaynaysa 205 ilaa 538°C, 20CrMnTi Bearing/Gearing steel waxa lagu shaqayn karaa si qabow iyadoo la isticmaalayo farsamooyinka caadiga ah ee xaaladaha la tirtiray ama caadiga ah.
