Intshayelelo yemveliso
I-AISI 4140 I-Steel Bar, i-Steel Plate, i-Flats Supplier, i-Stockist kunye ne-Exporter. I-AISI SAE 4140 intsimbi yengxubevange yintsimbi ye-chromium molybdenum ingxubevange esetyenziswa ngokubanzi kwinjongo ngokubanzi yentsimbi ephezulu yokuqina kumalungu, njengee-asi, iishafti, iibholiti, iigiya kunye nezinye izinto zokusebenza. Ifana ne-alloy grade AISI 4130 chrome moly alloy steel kodwa inomxholo wekhabhoni ephezulu. Umxholo ophezulu wekhabhoni we-AISI 4140 wensimbi unika amandla amakhulu kunye nobuchule bokunyanga ukushisa xa kuthelekiswa ne-AISI / ASTM 4130 i-alloy steels, nangona kunjalo ineempawu ezingaphantsi kwe-weldability.

5. Ukubumba
Ukushisa insimbi ngononophelo, ukushisa kwi-1150 oC - 1200 oC ubuninzi, ubambe kuze kube yilapho izinga lokushisa lifanayo kulo lonke icandelo.
Musa ukufogila ngaphantsi kwe-850 oC. Emva kokusebenza ngobuqhetseba umsebenzi kufuneka upholiswe kancinane kangangoko.
6. AISI 4140 Steel Grade Heat Treatment
- Ukuhlaziya
Ukushisa i-ASTM 4140 intsimbi ukuya kwi-800 oC - 850 oC, ubambe kuze kube yilapho iqondo lokushisa lilingana kulo lonke icandelo kwaye lipholile kwisithando somlilo.
- Ukulungelelanisa
I-alloy ye-Heat steel 4140 ukuya kwi-870 oC - 900 oC, yibambe de iqondo lokushisa lifane kulo lonke icandelo, gcoba imizuzu eyi-10 ukuya kwe-15 kwaye uphole emoyeni opholileyo.
- Ukufudumeza
Ukufudumeza kwakhona i-4140 grade yensimbi ukuya kwi-550 oC - 700 oC njengoko kufuneka, bamba de iqondo lokushisa lifane kulo lonke icandelo, cwilisa iyure enye nge-25 mm yecandelo, kwaye upholile emoyeni opholileyo.
7. Ukuqina kwe-AISI Alloy Steel 4140
I-AISI i-alloy 4140 ibha yensimbi, ipleyiti kunye nesikwere inokuqiniswa ngokusebenza okubandayo, okanye ukufudumeza kunye nokucima.
I-SAE 4140 intsimbi ye-alloy idla ngokubonelelwa ngobushushu obulungele ukunyangwa kubulukhuni kwi-18-22 HRC. Ukuba unyango olongezelelweyo lufunekayo, fudumeza ukuya kwi-840 oC - 875 oC, ubambe de iqondo lokushisa lifane kulo lonke icandelo, cwilisa imizuzu eyi-10 ukuya kwe-15 ngecandelo le-25 mm, kwaye ucime ioli, amanzi, okanye i-polymer njengoko kufuneka.
8. Ukusetyenziswa kwe-AISI alloy round 4140 bar yentsimbi
I-ASTM ingxubevange ye-4140 yentsimbi yentsimbi, imathiriyeli yeflethi okanye ipleyiti ingasetyenziselwa njengeentlobo ezininzi zezicelo apho ukuqina okukhulu kunye nokumelana nokunxiba kufuneka kumanqanaba asezantsi ekhabhoni. Usetyenziso oluqhelekileyo lokusetyenziswa kwesixhobo sentsimbi ye-4140 kuquka iMixholo, ii-Adapter, iiArbors, ii-strippers, iibhloko zesibambi, iziseko zomngundo, ii-ejectors, ugcino kunye nenkxaso yezixhobo, izixhobo, iijigs, umngundo, iikam, iikhola zokubhola, ii-Axle Shafts, iiBolts, ii-Crankshafts, ii-stubs, ukudityaniswa, imizimba ye-reamer, ii-asi, ishafting, ipiston rods, iinkunzi zeegusha, iishafti zoomatshini behydraulic, iigiya, isprockets, iiracks zegiya, amakhonkco amakhonkco, izipindu, izixhobo zezixhobo, izixhobo zokubamba izixhobo, iqhina, iinduku zokuqhagamshela, iChuck Bodies, Collets, Conveyor Pins & IiRoli, izikhonkwane ze-Ejector, iifolokhwe, iigiya, iintsimbi zeSikhokelo, iiShafts zeHydraulic kunye naMalungu, iLathe Spindles, iindawo zokugawulwa kwemithi, ii-Milling Spindles, ii-Motor Shafts, Nuts, Pinch Bars, iiPions, iPump Shafts, imivalo ekruqulayo, iingoma, izilayidi, imicu yokunxiba okanye iinxalenye. , ukwenza ukufa, ukufa kwebrake, ukufa kwe-trim, iibholster, iindawo zoomatshini kunye namalungu, njl.
Wamkelekile abathengi ukuba babuze i-AISI 4140 bar yentsimbi, ipleyiti, intsimbi ecaba ngexabiso lentsimbi ye-4140. Singababoneleli abaqeqeshiweyo kwaye sithumela ngaphandle iminyaka engaphezu kwe-12. Sikunika isisombululo sehlabathi jikelele se-aisi alloy 4140 bar yentsimbi.
