Kunzwisisa Musiyano Uripo Pakati peCarbon Steel uye Alloy Steel
Tsanangudzo yeCarbon Steel uye Alloy Steel
Simbi, sezvatinoziva tese, izwi rinowanzoreva iron-carbon alloys. Carbon steel (yakadimburirwa secarbon steel) isimbi-carbon alloy ine kabhoni inodzika isingasviki 2.11%. Mukugadzirwa kwayo kemikari, kunze kwesimbi nekabhoni, kune zvakare mashoma tsvina sesilicon, manganese, phosphorous, uye sarufa, uye hapazove nemamwe maalloying elements.
Kubuda kwekabhoni simbi inokwana 80% yehuwandu hwesimbi inobuda, uye inoshandiswa zvakanyanya mukuvaka, mabhiriji, mota, ngarava, kugadzira michina, indasitiri, petrochemicals, kuvandudza kwemugungwa nemimwe minda.
Alloy simbi isimbi ine imwe kana kupfuura zvimwe zvinosanganiswa zvinhu zvinowedzerwa kune kabhoni simbi, senge chromium, nickel, tungsten, titanium, vanadium, manganese, mhangura, aluminium, molybdenum, nezvimwewo, kuitira kuwedzera zvimwe zvinhu zvesimbi. Aya makemikari zvinhu anowedzerwa muzvikamu zvakasiyana / musanganiswa kuti ape zvinhu zvakasiyana mhedzisiro, senge kuwedzera kuomarara, kunatsiridza marara kuramba, kuwedzera simba, kuvandudza kuumbwa, kushandura weldability, nezvimwe.
Kubuda kwealloy simbi inokwana makumi maviri muzana yesimbi inobuda uye inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana sekugadzira michina, petrochemicals, kuvaka, makemikari ezuva nezuva, midziyo yekurapa, masynthetic fibers, zvekufambisa, nezvimwe.
Kurongwa kweCarbon Steel uye Alloy Steel
- Kurongeka kwekabhoni simbi
Zvinoenderana nekabhoni yemukati, inogona kukamurwa kuita: yakaderera kabhoni simbi, yepakati kabhoni simbi, yakakwira kabhoni simbi; iyo yakakwirira ye carbon content, iyo yakakwirira kuoma uye yakaderera iyo kuoma.
Yakaderera kabhoni simbi: kabhoni yemukati C% ≤0.25%. Masimbi akajairika akaderera kabhoni anoshandiswa kugadzira fasteners anosanganisira A3 simbi, Q215A simbi, Q235 simbi, 20# simbi, 22# simbi, nezvimwe.
Medium carbon steel: carbon content 0.25%＜C%≤0.45%. Yakajairwa yepakati kabhoni simbi dzinoshandiswa kugadzira fasteners dzinosanganisira 35# simbi, 45# simbi, nezvimwe.
Yakakwira kabhoni simbi: kabhoni yemukati C% ~ 0.45%, yakakwira kabhoni simbi haisati yashandiswa kugadzira mafasteners pamusika, nekuda kweiyo yakakwira kabhoni yemukati, yakaoma uye brittle zvinhu, zviri nyore kupaza.
- Kurongeka kwesimbi yealloy
Zvinoenderana nehuwandu hwehuwandu hwezvinhu zvealloy, yakakamurwa kuita: yakaderera alloy simbi, yepakati alloy simbi, yakakwirira alloy simbi, ine akasiyana alloy zvemukati uye kuumbwa, uye mashandiro akasiyana.
Yakaderera alloy simbi: yakazara alloy content ≤5%;
Medium alloy simbi: 5%＜yakazara alloy zvemukati ≤10%
Yakakwira alloy simbi: alloy zvemukati ~ 10%.
Masimbi akajairika alloy anoshandiswa kugadzira fasteners anosanganisira: 30CrMo, 40Cr, 35CrMo, 42CrMo, nezvimwe.
Hunhu hweCarbon Steel uye Alloy Steel
- Hunhu hwekabhoni simbi
Kuita kwekabhoni simbi kunoenderana nekabhoni yayo. Iyo yakakwira iyo kabhoni yemukati, iyo yakakwirira simba uye kuoma, uye kuderera kwepurasitiki, kuoma uye weldability.
Zvakanakira: plastiki yakanaka uye weldability; mutengo wakachipa, nyore kunhuwa; yakanaka yekugadzirisa tekinoroji; kushanda kunogona kuvandudzwa nekugadzirisa carbon content kana kuchinja nzira yekugadzirisa;
Zvakaipa: simba shoma shoma; kuoma kuoma; kusakwana kuderera kwekushisa kwekudzivirira; kushomeka kwekudzikira; low magnetic conductivity; zviri nyore kuve magineti mundima yemagineti.
- Hunhu hwe alloy simbi
Zvinhu zvakasiyana-siyana zvealloy zvakawedzerwa zvine maitiro akasiyana.
Zvakanakira: kuita kwakanaka kuzere; inowanikwa nokuda kwezvinangwa zvakakosha; simba rakakwirira uye kusimba kwepamusoro; kunaka kuomarara, kwete nyore kukanganisa uye kutsemuka; kupfeka kuramba, corrosion resistance, kudzikira tembiricha kuramba, tembiricha kuramba, kwete-magnetic, nezvimwewo;
Zvakaipa: zvinodhura; zvakanyanya kuoma kuumba uye kupisa kurapwa maitiro.
Kushandiswa kweCarbon Steel uye Alloy Steel
- Kushandiswa kwekabhoni simbi
Simbi yekabhoni inowanzo shandiswa kugadzira zvakasiyana siyana zvekuvaka, midziyo, mabhokisi, mitumbi yevira nemichina yekurima, zvidimbu zvidiki zvinotakura zvinhu, washer, mapini ecotter, tambo dzeti, zvitambi uye zvikamu zvakasungwa, nezvimwe.
Carbon steel inoshandiswa kugadzira fasteners
Q215A simbi yakakodzera kugadzira washers;
Q235 simbi inokodzera kugadzira mabhaudhi, nzungu, screw sleeves, cotter pini, rivets, nezvimwewo, uye inonyanya kushandiswa kune zvigadzirwa zvisina kuoma zvinodiwa se4.8-giredhi mabhaudhi, 4-giredhi nzungu, uye madiki screws;
35# simbi uye 45# simbi ndeyemhando yepamusoro kabhoni simbi zvimiro, uye anonyanya kushandiswa kugadzira 8.8-giredhi mabhaudhi, 8-giredhi nzungu uye 8.8-giredhi hexagon fasteners.
- Kushandiswa kwesimbi alloy
Alloy simbi inogona kushandiswa kugadzira zvikamu zvemotokari dzekutakura senge mota, ngarava, uye ndege; zvikamu zvematurusi emuchina, maroketi, zvinokandwa, nezvimwe; uye kugadzira mabhengi akasiyana-siyana anotenderedza, maturusi ekucheka, maturusi ekuyeresa, zvitubu, zvinopisa uye zvinotonhora mold, kukungurutsa mold, zvitubu, zviridzwa, nezvimwe.
Inoshandiswa muzviitiko zvakakosha, nharaunda isingadzivirirwe uye inodzivirira kupisa, senge turbines, boilers, makemikari michina, nezvimwe.
Alloy simbi inoshandiswa kugadzira fasteners
Inonyanya kushandiswa kugadzira mabhaudhi akasimba uye nzungu, senge 10.9 giredhi zvinhu zvinosanganisira 30CrMo uye 40Cr; 12.9 giredhi zvinhu zvinosanganisira: 35CrMo, 42CrMo, nezvimwe.
30CrMo inowanzoshandiswa kugadzira mabhaudhi uye matudhi pasi pemitoro yakakwira; zvigadziriso zvakasiyana-siyana zvinoshandiswa mukupisa kwepamusoro (pazasi pe450 ℃) nharaunda senge ma turbines eutsi uye boilers; flanges uye nzungu dzinoshandiswa mukupisa kwakanyanya (pasi pe500 ℃) nharaunda dzekumanikidza;
40Cr yakakodzera kugadzira screw sleeves, pini, yekubatanidza tsvimbo screws, nzungu, nezvimwewo;
35CrMo inowanzo shandiswa kugadzira mafasteners akasiyana-siyana pasi pemitoro yakakwira, senge zvisungo zvemajenareta emhepo; zvigadziriso zvakasiyana-siyana zvinoshandiswa mukupisa kwepamusoro (pasi pe480 ℃) nharaunda dzakadai semaboilers;
42CrMo inokodzera kugadzira fasteners inoda simba repamusoro kupfuura 35CrMo.
Tichifunga nezvehunhu hwekabhoni simbi uye alloy simbi, pakusarudza fastener zvinhu, kabhoni simbi inogona kupihwa pekutanga pane iyo nhanho yekusangana nezvinodiwa zvekushandisa; kana izvo zvakatemwa zvakakura, chimiro chakanyanya kuoma, uye simba uye nechaizvo zvinodiwa zvakakwirira, kana pane zvinodiwa zvekuoma kunopisa uye mamwe maitiro akakosha, ipapo alloy simbi inofanira kushandiswa.
Mushure mekuverenga izvi, unogona here kusiyanisa pakati pekabhoni simbi uye alloy simbi?
