Introduction to ASTM A519 AISI 4130 Alloy Seamless Steel Pipe

4130 ndi chitsanzo cha chitoliro chachitsulo cha chromium molybdenum alloy.

Chitoliro chachitsulo cha Chromium molybdenum ndi mtundu wa chitoliro chachitsulo chosasunthika, ndipo magwiridwe ake ndi apamwamba kwambiri kuposa mapaipi wamba achitsulo chosasunthika. Chifukwa mtundu uwu wa chitoliro chachitsulo uli ndi Cr yambiri, kutentha kwake kwakukulu, kutentha kochepa, komanso kukana dzimbiri sikufanana ndi mapaipi ena achitsulo chosasunthika. Chifukwa chake, mapaipi a alloy amagwiritsidwa ntchito kwambiri m'mafakitale monga mafuta, mankhwala, mphamvu, ndi ma boiler.

Kodi chitoliro chachitsulo cha 4130 ndi cha mtundu wanji?

4130 ikufanana ndi mtundu wa 30CrMo wakunyumba, ndipo mphamvu yake yomangika nthawi zambiri imakhala yoposa 700MPa. Waya wowotcherera umafunika kugwiritsa ntchito waya wowotcherera wamphamvu kwambiri wa ER70-G, womwe mungafunse mukaugula.

Muyezo waku AmericaASTM/AISI 4130Chitoliro chachitsulo cha aloyi Kapangidwe ka mankhwala: C: 0.28~0.33 Si: 0.15~0.35 Mn: 0.40~0.60 S ≤ 0.040 P ≤ 0.040 Cr: 0.80~1.10 Mo: 0.15~0.25
Kapangidwe ka makina ka AISI 4130 kokhazikika ku America: mphamvu yokoka: ≥ 620MPa, mphamvu yotulutsa: ≥ 415MPa, kutalika pambuyo posweka: ≥ 20%, ndipo kumatha kuzimitsidwa ndikuchepetsedwa malinga ndi zosowa za makasitomala.
AISI yokhazikika yaku AmericaChitoliro chachitsulo cha aloyi cha 4130momwe kutumiza kumachitikira: kutentha kozungulira kapena kutentha kotheratu komanso kofewa
Mafotokozedwe ndi miyeso: 60.3-765 * 5-120, mainchesi omwe amagwiritsidwa ntchito kwambiri: 60.3, 73, 88.9, 101.6, 114.3, 141.3, 168.3, 219.1, 273.1, 323.9, 355.6, 406.4, 457.2, 508, 559, 610, 660, 711, 762. Makulidwe ena amathanso kusinthidwa malinga ndi zosowa za makasitomala.
Chitoliro chachitsulo chosasunthika cha American Standard 4130: chomwe chimagwiritsidwa ntchito makamaka pazida zofufuzira mafuta, zida zobowola, zida zopangira mafuta amakina, zida zobowola mafuta ndi zopangira, komanso zida zofunika pakusonkhanitsa ndi kunyamula mafuta ndi gasi wachilengedwe.
