20Cr inopisa yakakungurutswa simbi pepa

GB 20Cr alloy Simbi isimbi yemhando yepamusoro Quenched and Tempered Alloy Structural steel, Ndeyemhando yepamusoro yakaderera kabhoni,Low alloy chromium, molybdenum, nickel kesi yekuomesa simbi. Oiri Yakadzimwa & Kupisa Kuoma ndeye 28-34 HRc. GB 20Cr simbi Annealing delivery inoomesa isingasviki 250HB.20Cr Iine yakaderera carbon content range, Saka GB 20Cr alloy simbi ine weldability yakanaka.

GB 20Cr alloy simbi yakaenzana tsanangudzo: ASTM A29/A29M, DIN EN 10083/3, JIS G4053 uye GB/T 3077. GB 20Cr yakaenzana nesimbi yakatenderedza bhari uye flat bars inogona kutemwa kune ako anodiwa saizi. China simbi 20Cr inopisa yakakungurutswa uye forged simbi bhaa inogonawo kupihwa, ichipa yakakwira mhando simbi simbi chaiyo pasi turusi bhaa kune ako anodiwa kushivirira. GB 20Cr simbi yakaenzana mabhawa anopihwa akatenderera, sikweya uye flat zvimiro.
GB 20Cr alloy Simbi ndeyemhando yepamusoro Yakadzimwa uye Tempered Alloy Structural simbi. Ndeyemhando yepamusoro yakaderera kabhoni,Low alloy chromium, molybdenum, nickel kesi inoomesa simbi. Oiri Yakadzimwa & Yakashatirwa GB 20Cr Simbi Kuoma ndeye 28-34 Hrc. GB 20Cr simbi Annealing kuburitsa inoomesa isingasviki 250HB. Iine yakaderera kabhoni yemukati renji, GB 20Cr alloy simbi yakaenzana ine yakanaka weldability.
GB 20Cr forged simbi bhaa uye inopisa yakatenderedzwa simbi bhaa inoshandiswa zvakanyanya kune dzakasiyana siyana mashandisirwo muinoshandiswa mumaindasitiri emotokari uye einjiniya kune vane maturusi uye zvimwe zvinhu zvakadaro. Inonyanya kushandiswa mukugadzira kudiwa kwakakwira, kusimba kwekupfeka kwemoyo, pasi pechikamu pasi pe30 mm kana zvidimbu zvidiki zvecarburized yechimiro chakaomarara uye mutoro (kudzima mafuta), senge: giya rekutumira, giya shaft, CAM, worm, piston. pin, claw clutch, nezvimwewo

Kuenzaniswa ne15Cr simbi, ine simba repamusoro uye kuoma. Iyo yakakosha kuomesa dhayamita mumafuta inosvika 4-22mm, uye iyo yakaoma kuomarara dhayamita mumvura inosvika 11-40mm, asi kuoma kwayo kwakashata. Pane katsika kekuti zviyo zvikure, uye kudzima kwakananga pakutonhodza kune simba guru pakuoma kwesimba. Naizvozvo, mushure mekuvhiyiwa, kudzima kwechipiri kunodiwa kuti uvandudze kuoma kwechikamu chepakati pasina brittleness; simbi ine high cold strain plasticity uye inogona kudhonzwa mumamiriro ekutonhora. ; Machinability yakanaka pasi pepamusoro tembiricha normalizing kana quenching uye tempering mamiriro, asi murombo pashure annealing; 20Cr is pearlite, ine weldability yakanaka, kazhinji haidi kurapwa kwekupisa mushure mekuputira, asi zvikamu zvine ukobvu kupfuura 15mm zvinoda kupiswa isati yave welding Kana yasvika 100～150 ℃, kupisa kupisa kurapwa hakudiwi mushure mekupisa.

Mechanical properties

Yakaenzana ne20Cr alloy Structure Simbi

Kupisa kurapwa kwakabatana

• Kuiswa kwe20Cr Alloy structural steel

Zvishoma nezvishoma kupisa kusvika ku850 ℃ uye bvumira nguva dzakakwana, rega simbi inyatsopisa, Wobva watonhorera zvishoma nezvishoma muchoto. Iyo 20Cr alloy simbi ichawana MAX 250 HB (Brinell kuoma).

• Kuomeswa kweGB Alloy zvimiro simbi 20Cr

Kutanga kudzima kunopisa zvishoma nezvishoma kusvika 880 ° C, Zvadaro mushure mekunyorova kwakakwana pane iyi tembiricha dzima mumafuta kana mvura. Hasha kana maturusi asvika mukamuri tembiricha. Chechipiri kudzima kupisa kusvika 780-820 ° C, ipapo kudzima mumafuta kana mvura.

• Kupisa kwe20Cr Alloy simbi yekugadzira

Kupisa kusvika 20 ° C, wozotonhorera mumvura kana mafuta.normal delivery hardness 179HB Min.

Applications

GB 20Cr simbi inoshandiswa zvakanyanya kune akasiyana maapplication mune anoshandiswa mumaindasitiri emotokari uye einjiniya kune vane zvishandiso uye zvimwe zvinhu zvakadaro. Inonyanya kushandiswa mukugadzira kudiwa kwakakwira, kusimba kwekupfeka kwemoyo, pasi pechikamu pasi pe30 mm kana zvidimbu zvidiki zvecarburized yechimiro chakaomarara uye mutoro (kudzima mafuta), senge: giya rekutumira, giya shaft, CAM, worm, piston. pini, claw clutch, nezvimwewo; Zvekupisa kurapwa deformation uye yakakwira abrasion resistance parts, inofanira kunge iri high frequency surface quenching after carburizing, senge modulus isingasviki 3 yegiya, shaft, spline shaft, etc. Simbi iyi inogona kushandiswa mukudzimwa uye kushatirwa. inoshandiswa mukugadzirwa kwehombe nepakati pasi pesimba rekuita munzvimbo dzayo dzebasa, rudzi urwu rwesimbi zvakare runogona kushandiswa seyakaderera kabhoni martensite simbi inodzima, ichiwedzera kuwedzera simbi goho simba uye tensile simba rakawedzera (anenge 1.5 ~ 1.7 nguva). Zvishandiso zvakajairika senge miviri yevharuvhu, pombi uye zvigadziriso, Shaft, kuremerwa kwevhiri, mabhaudhi, mabhaudhi ane misoro miviri, magiya, nezvimwe.

Saizi yenguva dzose uye Kushivirira

Simbi yakatenderedza bhawa: Diameter Ø 5mm - 3000mm

Simbi ndiro: Ukobvu 5mm - 3000mm x Upamhi 100mm - 3500mm

Simbi Hexagonal bar: Hex 5mm - 105mm

Vamwe 20Cr havasati vataura saizi, pls bata timu yedu yekutengesa ine ruzivo.

Processing

GB 20Cr alloy simbi kutenderera bhaa uye zvikamu zvakafuratira zvinogona kutemwa kune ako anodiwa saizi. 20Cr alloy simbi yepasi bar inogonawo kupihwa, ichipa yakakwira mhando simbi simbi chaiyo pasi turusi simbi bar kune ako anodiwa kushivirira. GB 20Cr simbi inowanikwawo seGround Flat Stock / Gauge Plate, mune yakajairwa uye isingaenzaniswi saizi.
