I-A105 yezinto eziphathekayo ityhubhu yentsimbi

I-A105 yinombolo yomgangatho we-ASTM yaseMelika, kwaye i-A imele i-carbon structural steel eqhelekileyo.
Igama eliqhelekileyo: i-carbon steel forgings yamacandelo ombhobho.Ngenxa yokuba enye kuphela i-carbon steel forging ichazwe kulo mgangatho, i-A105 yinqanaba le-carbon steel lokubumba.I-A105 nayo ikhowudi yezinto eziphathekayo, eyeyentsimbi ekhethekileyo kwaye iyintsimbi ebandayo.I-A105 yintsimbi ephantsi ye-carbon steel forging, efana nentsimbi ye-20.Kukho imigangatho emibini, omnye ngumgangatho waseMelika weASTM A105/A105M weCarbon Steel Forgings for Piping Components, kwaye omnye ngumgangatho waseTshayina we-GB/T12228-2006 iMiqathango yobuGcisa yeCarbon Steel Forgings kwiVavelu yeNjongo Jikelele.
Ukuqulunqwa 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.
Iipropati zomatshini ziphakathi kweNombolo ye-20 yentsimbi ekhandiweyo kunye ne-16Mn yentsimbi edibeneyo.
