Isingeniso somkhiqizo
I-AISI 4140 Ibha Yensimbi, I-Steel Plate, Umhlinzeki WamaFlats, Stockist kanye Nomthengisi. I-AISI SAE 4140 ingxubevange yensimbi iyisicaciso sensimbi ye-chromium molybdenum alloy esetshenziswa kabanzi ngokwenjongo evamile insimbi eqinile ephezulu ezingxenyeni, njengama-ekseli, amashafu, amabhawodi, amagiya nezinye izinhlelo zokusebenza. Ifana ne-alloy grade AISI 4130 chrome moly alloy steel kodwa enokuqukethwe kwekhabhoni ephakeme kancane. Okuqukethwe kwekhabhoni ephezulu yensimbi ye-AISI 4140 kunikeza amandla amakhulu namandla okwelapha ukushisa uma kuqhathaniswa ne-AISI / ASTM 4130 alloy steels, nokho inezici eziphansi zokushisela.

5. Ukuqamba
Shisisa insimbi ngokucophelela, ukushisa ku-1150 oC - 1200 oC esiphezulu, ubambe kuze kube yilapho izinga lokushisa lifana nengxenye yonke.
Ungafoji ngaphansi kuka-850 oC. Ngemva kokusebenza kokufojitha isiqeshana somsebenzi kufanele sipholiswe kancane ngangokunokwenzeka.
6. AISI 4140 Steel Grade Heat Treatment
- Anealing
Shisisa izinsimbi ze-ASTM 4140 ziye ku-800 oC - 850 oC, ubambe kuze kube yilapho izinga lokushisa lifana nengxenye yonke futhi liphole esithandweni.
- Ukujwayela
Ingxube ye-Heat steel 4140 kuya ku-870 oC - 900 oC, yibambe kuze kube yilapho izinga lokushisa lifana nengxenye yonke, cwilisa imizuzu eyi-10 - 15 futhi uphole emoyeni onganyakazi.
- Ukuthukuthela
Shisisa kabusha insimbi yezinga elingu-4140 iye ku-550 oC - 700 oC njengoba kudingeka, bamba kuze kube yilapho izinga lokushisa lilingana endaweni yonke, cwilisa ihora elingu-1 ngo-25 mm wesigaba, futhi uphole emoyeni onganyakazi.
7. Ukuqina kwe-AISI Alloy Steel 4140
I-AISI alloy 4140 ibha yensimbi, ipuleti nesikwele kungenziwa lukhuni ngokusebenza okubandayo, noma ukufudumeza nokucisha.
I-SAE 4140 alloy steel ivamise ukunikezwa ukushisa okulungele ukulashwa kubulukhuni ngo-18-22 HRC. Uma kudingeka okunye ukwelashwa kokushisa, shisisa ufike ku-840 oC - 875 oC, ubambe kuze kube yilapho izinga lokushisa lifana nengxenye yonke, cwilisa imizuzu engu-10 - 15 ngesigaba esingu-25 mm, futhi ucime uwoyela, amanzi, noma i-polymer njengoba kudingeka.
8. Ukusetshenziswa kwe-AISI alloy round 4140 bar yensimbi
Ibha yensimbi ye-ASTM alloy 4140, impahla eyisicaba noma yepuleti ingasetshenziselwa njengezinhlobonhlobo zezinhlelo zokusebenza lapho ukuqina okukhulu nokumelana nokugqokwa kuyadingeka ngaphezu kwamabanga aphansi ekhabhoni. Izinhlelo zokusebenza ezijwayelekile zokusetshenziswa kwensimbi yamathuluzi angu-4140 zihlanganisa Izingxenye, Ama-adaptha, Ama-Arbor, ama-strippers, izibambi, ama-mold bases, ama-ejectors, ukwenza isipele nokusekela amathuluzi, ama-fixtures, ama-jigs, ama-molds, ama-cams, ama-drill collar, ama-Axle Shafts, ama-Bolts, ama-Crankshafts, ama-stubs, ama-coupling, imizimba ye-reamer, ama-ekseli, i-shafting, ama-piston rods, izinqama, amashafti emishini esebenza ngomshini, amagiya, ama-sprocket, ama-gear racks, amaketango, ama-spindle, imizimba yamathuluzi, izibambi zamathuluzi, ama-tie rods, Connection Rods, Chuck Bodies, Collets, Conveyor pin & Amaroli, Izikhonkwane Zokukhipha, Amafoloko, Amagiya, Izinduku Zokuqondisa, Izigxobo Nezingxenye Ze-Hydraulic, Ama-spindle e-Lathe, Izingxenye Zokugawula, Ama-Milling Spindle, Ama-Motor Shaft, Amantongomane, Ama-Pinch Bar, Ama-Pionions, Ama-Pump Shafts, imigoqo eyisicefe, amathrekhi, amaslayidi, ama-wear strips noma izingxenye , ukwakha ama-dies, ama-brake dies, ama-trim dies, ama-bolster, izingxenye zemishini kanye nezingxenye, njll.
Siyakwamukela amakhasimende ekubuzeni ibha yensimbi ye-AISI 4140, ipuleti, insimbi eyisicaba ngentengo yensimbi engu-4140. Singabahlinzeki abaqeqeshiwe nabathumela ngaphandle iminyaka engaphezu kwe-12. Sikunikeza isisombululo somhlaba wonke se-aisi alloy 4140 steel bar.
