I-SAE4340 Steel Round Bar ASTM4340 Induku Yensimbi
Izici
Impahla ye-4340 yensimbi yensimbi iyinsimbi yesakhiwo se-alloy.Ilingana ne-German DIN steel grade 36CrNiMo4 , French NF standard 40NCD3, Japanese JIS standard SNCM439, British BS standard 816M40, American SAE/ASTM4340, American UNS standard G43400，China Standard 40CrNiMoA.
I-SAE4340 yaziwa njengensimbi yesakhiwo esiyingxubevange noma insimbi eyinhlanganisela.Insimbi iqukethe i-nickel ephakathi kuka-1.65 no-2.00, enamandla amakhulu, ukuqina, ikhono eliphezulu lokuqina, nokuzinza ngokumelene nokushisa ngokweqile.Nokho, inokuzwela okuphezulu kumachashazi amhlophe kanye nokufutheka kwentukuthelo.Ukufundeka kahle, okudinga ukushisa okuphezulu ngaphambi kokushisela, ukukhululeka kwengcindezi ngemva kokushisela, kanye nokusetshenziswa ngemva kokushisisa.
IZINGA: ASTM A29/A29M-2012 noma i-SAE J404

Imininingwane yokwelashwa kokushisa
Icinywe ku-850 ℃, uwoyela upholile;Ukushisa ku-600 ℃, amanzi apholile, uwoyela upholile.
Isicelo
Okuvame ukusetshenziselwa ukukhiqiza izingxenye ezibalulekile ezinamandla amakhulu kanye nepulasitiki enhle, kanye nokukhiqiza izingxenye ezibalulekile ezinezidingo ezikhethekile zokusebenza ngemuva kokwelashwa kwe-nitrate:
-Imishini enzima enamashafu aphezulu
-I-Wheel shaft enobubanzi obungaphezu kuka-250mm
-I-rotor shaft yendiza enophephela emhlane
-I-turbine shaft, ama-blades, kanye nezingxenye zokudlulisa umthwalo ophezulu wenjini ye-turbojet
- Izixhumi ze-Crankshaft, amagiya, njll.
Iphakheji
1.Ngezinqwaba, isisindo senqwaba ngayinye singaphansi kwamathani ama-3, kokuncane kwangaphandleIbha eyindilinga enobubanzi, inyanda ngayinye enemicu yensimbi engu-4 - 8.
Isiqukathi esingamamitha angu-2.20 siqukethe ubukhulu, ubude obungaphansi kuka-6000mm
Isiqukathi esingamamitha angu-3.40 siqukethe ubukhulu, ubude obungaphansi kuka-12000mm
4.Ngomkhumbi omningi, Inkokhelo Yempahla iphansi ngempahla eyinqwaba, futhi inkuluosayizi abasindayo abakwazi ukulayishwa ezitsheni zokuhambisa ngempahla enkulu
Iphakheji
Ukuqinisekisa ikhwalithi
1. Qinisa Ngokuvumelana Nezimfuneko
2. Isampula: Isampula iyatholakala.
3. Izivivinyo: Ukuhlolwa kwesifutho sikasawoti / Ukuhlolwa kwe-Tensile / Ukuhlolwa kwe-Eddy yamanje / Ukwakheka kwamakhemikhali ngokwesicelo samakhasimende
