A105 steel tube impahla

I-A105 iyinombolo ejwayelekile ye-ASTM yaseMelika, futhi u-A umele insimbi evamile ye-carbon structural.
Igama elijwayelekile: i-carbon steel forgings yezingxenye zamapayipi.Ngenxa yokuthi i-carbon steel forging eyodwa kuphela eshiwo kuleli zinga, i-A105 iyizinga le-carbon steel lokuqanjwa.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.
Ukubunjwa C: ≤ 0.35 Si: ≤ 0.35 Mn: 0.6-1.05 S: ≤ 0.050 P: ≤ 0.040, Cu ≤ 0.4 Ni ≤ 0.4 Mo ≤ 0.12 V ≤0 Cr3 ≤ 0.12 V ≤0 ≤0.
Izakhiwo zemishini ziphakathi kuka-No. 20 forged steel kanye ne-16Mn forged steel.
