Chii chaunoziva nezve forging A105?

Zita rakajairika: carbon steel forgings yezvikamu zvepombi.
Nokuti rudzi rumwe chete rwekabhoni simbiforginginotsanangurwa mune iyi chiyero, A105 inoonekwa zvakare seye carbon simbi giredhi rekugadzira.
A105 zvakare ikodhi yezvinhu, inova yesimbi yakakosha uye inotonhora yesimbi.
A105isimbi yakaderera kabhoni forging, yakafanana nesimbi makumi maviri. 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.

A105 carbon structure simbi
A105 ndiyo American ASTM yakajairwa nhamba, ASTM A105/A105M kabhoni simbi yekugadzira zvinhu zvepombi, uye A inomiririra yakajairwa kabhoni dhizaini simbi. Ndeyesimbi yakakosha uye imhando yesimbi inotonhora. A105 isimbi yakaderera kabhoni forging, yakafanana nesimbi makumi maviri.
Cherechedza: Muchirongwa chepombi, kazhinji A105 inogona kutsiva Nhamba 20, asi Nha. Nekudaro, iyo stress corrosion cracking (SCC) kuramba kweA105 yakashata zvishoma kupfuura iyo yeNo.

A105 Ndezvipi zvinhu zvakasiyana ne20 simbi
A105 isimbi yakaderera kabhoni simbi. Iyo kabhoni yemukati yekabhoni structural simbi inenge 0.05% ~ 0.70%, uye mamwe anogona kunge akakwira se0.90%. A105 ndiyo American ASTM chiyero nhamba, uye A inomiririra yakajairwa kabhoni dhizaini simbi. Mune iyi chiyero, imwe chete mhando yekabhoni simbi yekugadzira inotsanangurwa, uye A105 inoonekwa zvakare segiredhi simbi yekugadzira. A105 zvakare ikodhi yezvinhu, inova yesimbi yakakosha uye inotonhora yesimbi. A105 isimbi yakaderera kabhoni forging, yakafanana nesimbi makumi maviri. 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. Iyo kabhoni yemukati yekabhoni structural simbi inenge 0.05% ~ 0.70%, uye mamwe anogona kunge akakwira se0.90%. Muchirongwa chepombi, kazhinji A105 inogona kutsiva Nhamba 20, asi Nha. Nekudaro, iyo stress corrosion cracking (SCC) kushorwa kweA105 yakashata zvishoma kupfuura iyo yeNo.
Inogona kukamurwa kuita yakajairwa kabhoni structural simbi uye yepamusoro-mhando kabhoni structural simbi. Iine zvakawanda zvekushandisa uye inoshandisa yakawanda yakawanda. Inonyanya kushandiswa muchitima, bhiriji, mapurojekiti ekuvaka akasiyana siyana, kugadzira simbi dzakasiyana-siyana dzinotakura mitoro, uye zvisingakoshi zvemechani zvikamu uye zvakajairika weldments izvo zvisingade kurapwa kupisa.
