A105 simbi chubhu zvinhu

A105 ndiyo American ASTM chiyero nhamba, uye A inomiririra yakajairwa kabhoni dhizaini simbi.
Zita rakajairika: carbon steel forgings yezvikamu zvepombi.Nekuti imwe chete kabhoni simbi yekugadzira inotsanangurwa mune iyi chiyero, A105 inotova kabhoni simbi giredhi rekugadzira.A105 zvakare ikodhi yezvinhu, inova yesimbi yakakosha uye inotonhora yesimbi.A105 isimbi yakaderera kabhoni forging, yakafanana ne20 simbi.Pane zviyero zviviri, imwe ndeyeAmerican standard ASTM A105/A105M Carbon Steel Forgings yePiping Components, uye imwe yacho ndiyo Chinese standard GB/T12228-2006 Technical Conditions yeCarbon Steel Forgings yeGeneral Chinangwa Mavhavha.
Chimiro 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.
The mechanical properties dziri pakati No. 20 forged simbi uye 16Mn forged simbi.
