Pane nguva dzose chishandiso chakakodzera chebasa racho, uye kazhinji pane kwete, chinoda simbi chaiyo kugadzira icho chishandiso.A2 ndiyo yakajairika giredhi resimbi simbi inoshandiswa kugadzira maturusi ekuumba simbi, huni, uye zvimwe zvinhu.A2 yepakati-kabhoni chromium alloy simbi inhengo yeboka rinotonhora rekushandisa simbi, rakasarudzwa neAmerican Iron and Steel Institute (AISI), iyo inosanganisira O1 yakaderera-kabhoni simbi, A2 simbi uye D2 yakakwira-carbon yakakwira-chromium simbi.

Cold work tool simbi isarudzo yakanaka kune zvikamu zvinoda chiyero chekupfeka kuramba uye kuoma.Ivo zvakare vanoshanda nemazvo kune zvikamu zvinoda hushoma huwandu hwe shrinkage kana kukanganisa panguva yekuomesa maitiro.

Kupfeka kupikisa kweA2 simbi ndeyepakati pakati peO1 neD2 simbi, uye ine yakanaka machining nekukuya zvivakwa.A2 yakasimba kudarika D2 simbi, uye ine zvirinani dimensional control mushure mekupisa kupisa kupfuura O1 simbi.

Mune izwi, A2 simbi inomiririra kuenzana kwakanaka pakati pemutengo uye maitiro emuviri, uye inowanzoonekwa sechinangwa chakazara, simbi yepasirese.

Composition

A2 simbi ndiyo inonyanya kushandiswa yakasiyana-siyana yeGroup A simbi yakanyorwa muASTM A682 standard, iyo yakasarudzwa "A" yekuomesa mhepo.

Munguva yekupisa kupisa, iyo yepakati kabhoni yemukati inosvika 1% inobvumira A2 simbi kukudziridza kuoma kwakazara kuburikidza nekutonhodza mumhepo yakanyarara - iyo inodzivirira kukanganisa uye kutsemuka kunogona kukonzerwa nekudzima kwemvura.

Iyo yakakwira chromium yemukati (5%) yeA2 simbi, pamwe nemanganese uye molybdenum, inobvumira kuti iwane kuomarara kwakazara kwe57-62 HRC muzvikamu zvakakora (masendimita mana mudhayamita) - ichipa kugadzikana kwakanaka kwedimensional kunyangwe zvikamu zvakakura.

Applications

A2 simbi bar inowanikwa mune akati wandei mafomu, anosanganisira sikweya, denderedzwa, uye flat.Ichi chinhu chakasiyana-siyana chinogona kushandiswa kune akasiyana siyana maturusi anoda kusapfeka, senge sando dzemaindasitiri, mapanga, slitters, zvibhakera, zvibatiso zvematurusi, uye matanda ekucheka matanda.

Nekupinza uye mashizha, A2 simbi inopikisa kucheka kuitira kuti igare kwenguva refu, kazhinji ichiita kuti ive sarudzo ine hupfumi kupfuura high-carbon D2 type steel.

Inowanzoshandiswa kuvhara uye kugadzira shinda inofa, kutsika kunofa, kuchekerera kunofa, jekiseni mold inofa, mandrels, molds, uye ma spindles.

Shanghai Histar Metalinopa A2 chishandiso simbi bhaa mumativi, akafuratira uye akatenderera muhukuru hwakasiyana.Bata isu kuti uwane mutengo kana shanyira webhusaiti yedu.
