Yini oyaziyo nge-Forging A105?

Igama elijwayelekile: i-carbon steel forgings yezingxenye zamapayipi.
Ngoba uhlobo olulodwa kuphela lwe-carbon steelukuqambaicaciswe kuleli zinga, i-A105 nayo ithathwa njengebanga le-carbon steel lokuqanjwa.
I-A105 iphinde ibe yikhodi yezinto ezibonakalayo, okungeyensimbi ekhethekile futhi iyinsimbi ebunjiwe ebandayo.
A105iyi-carbon steel forging ephansi, efana nensimbi engama-20.Kunamazinga amabili, eyodwa iyi-American standard ASTM A105/A105M Carbon Steel Forgings for Piping Components, kanti enye iyi-Chinese standard GB/T12228-2006 Technical Conditions for Carbon Steel Forgings for General Purpose Valves.

I-A105 carbon structural steel
I-A105 inombolo ejwayelekile ye-ASTM yaseMelika, i-ASTM A105/A105M yensimbi yensimbi ye-carbon yezingxenye zamapayipi, futhi u-A umele insimbi evamile yesakhiwo sekhabhoni.Ingeyensimbi ekhethekile futhi iwuhlobo lwensimbi eyakhiwe ebandayo.I-A105 iyinsimbi ephansi ye-carbon steel, efana nensimbi engama-20.
Qaphela: Kuhlelo lwamapayipi, ngokuvamile i-A105 ingathatha indawo ye-No. 20, kodwa i-No.Kodwa-ke, ukumelana ne-stress corrosion cracking (SCC) kwe-A105 kubi kancane kunalokho kweNo.

I-A105 Iyiphi impahla ehlukile ku-20 steel
I-A105 iyi-carbon steel forging ephansi.Okuqukethwe kwekhabhoni yensimbi ye-carbon structural cishe ku-0.05% ~ 0.70%, kanti okunye kungaba phezulu ku-0.90%.I-A105 iyinombolo evamile ye-ASTM yaseMelika, futhi u-A umele insimbi evamile yesakhiwo sekhabhoni.Kuleli zinga, uhlobo olulodwa kuphela lwe-carbon steel forging lubaluliwe, futhi i-A105 nayo ibhekwa njengebanga le-carbon steel grade of forging.I-A105 iphinde ibe yikhodi yezinto ezibonakalayo, okungeyensimbi ekhethekile futhi iyinsimbi ebunjiwe ebandayo.I-A105 iyinsimbi ephansi ye-carbon steel, efana nensimbi engama-20.Kunamazinga amabili, eyodwa iyi-American standard ASTM A105/A105M Carbon Steel Forgings for Piping Components, kanti enye iyi-Chinese standard GB/T12228-2006 Technical Conditions for Carbon Steel Forgings for General Purpose Valves.Okuqukethwe kwekhabhoni yensimbi ye-carbon structural cishe ku-0.05% ~ 0.70%, kanti okunye kungaba phezulu ku-0.90%.Kuhlelo lwamapayipi, ngokuvamile i-A105 ingathatha indawo ye-No. 20, kodwa i-No.Kodwa-ke, ukumelana ne-stress corrosion cracking (SCC) kwe-A105 kubi kancane kunalokho kweNo.
Ingahlukaniswa ngensimbi evamile ye-carbon structural kanye nekhwalithi ephezulu ye-carbon structural steel.Inokusebenzisa okuningi futhi isebenzisa inani elikhulu.Isetshenziswa kakhulu kojantshi wesitimela, ibhuloho, amaphrojekthi wokwakha ahlukahlukene, ukukhiqiza izingxenye zensimbi ezahlukahlukene ezithwala imithwalo engashintshi, nezingxenye zemishini ezingabalulekile kanye nokushisela okujwayelekile okungadingi ukwelashwa kokushisa.
