10 # Umuyoboro udafite icyuma

Ibisobanuro bigufi:

Ibisobanuro ku musaruro:

Diameter yo hanze y'umuyoboro w'icyuma 20-426

Urukuta rw'icyuma rufite uburebure bwa 20-426

Ibigize imiti:

● No 10 ibyuma bidafite ibyuma bigize imiti:

Carbone C: 0.07 ~ 0.14 ″ silicon Si: 0.17 ~ 0.37 Manganese Mn: 0.35 ~ 0.65 Amazi ya S: ≤0.04 Fosifore P: ≤0.35 chromium Cr: ≤0.15 Nickel Ni: ≤0.25 Umuringa Cu: ≤0.25

Umutungo wa mashini:

Ibikoresho bya mashini ya No 10 umuyoboro wicyuma udafite ikidodo: Imbaraga zingutu σb (MPa): ≥410 (42) Imbaraga zitanga umusaruro σs (MPa): ≥245 (25) kurambura δ5 (%): ≥25 kugabanya igice (%): ≥5 , ubukana: budashyushye, ≤156HB, ingano yicyitegererezo: 25mm.

Ibyuma byiza bya karubone byubatswe:

No 10 umuyoboro w'icyuma udafite kashe ntukubiyemo ibindi bintu bivanze (usibye ibintu bisigaye) usibye karubone (C) hamwe na silikoni (Si) yo kwangiza (muri rusange ntabwo irenga 0,40%), manganese (Mn) (muri rusange ntabwo hejuru ya 0,80%, kugeza kuri 1.20%) ibintu bivanze.

Ibyuma nkibi bigomba kuba bifite imiterere yimiti hamwe nubukanishi.Ibiri muri sulfure (S) na fosifore (P) bigenzurwa munsi ya 0.035%.Niba igenzuwe munsi ya 0.030%, yitwa ibyuma byujuje ubuziranenge, kandi "A" igomba kongerwaho nyuma yamanota, nka 20A;Niba P iyobowe munsi ya 0.025% na S igenzurwa munsi ya 0.020%, byitwa ibyuma byujuje ubuziranenge, kandi "E" igomba kongerwaho nyuma y amanota kugirango yerekane itandukaniro.Kubindi bintu bisigaye bivanga byazanwe mubyuma nibikoresho fatizo, nka chromium (Cr), nikel (Ni), umuringa (Cu), nibindi, ibikubiye muri Cr≤0.25%, Ni≤0.30%, Cu≤0.25%.Ibiranga bimwe bya manganese (Mn) bigera kuri 1.40%, bizwi nkicyuma cya manganese.

No 10 ibyuma bidafite uburemere bwo kubara uburemere: [(diameter yo hanze - uburebure bwurukuta) * uburebure bwurukuta] * 0.02466 = kg / m (uburemere kuri metero)
