Product Overview
Thaum koj xav tau cov khoom siv kho tshuab uas tuaj yeem ua haujlwm hnyav yam tsis muaj kev cuam tshuam qhov loj me, 40CrNiMo peev casting muab qhov zoo tshaj plaws ntawm ob lub ntiaj teb. Qhov nruab nrab no -carbon alloy structural steel- feem ntau hu ua quenched thiab tempered steel-combines siab tensile zog, zoo heev toughness, thiab sib sib zog nqus hardenability, ua rau nws cov khoom ntawm kev xaiv rau cov khoom tseem ceeb nyob rau hauv hnyav machinery, tsheb tsav tsheb, aerospace systems, thiab cov khoom siv zog.
Tsis zoo li cov pa roj carbon steel casting uas feem ntau yuav tsum tau siv ntau qhov kev siv tshuab, kev nqis peev cam khwb cia 40CrNiMo cov khoom tawm los ntawm cov txheej txheem nyob ze -net- cov duab, nrog rau qhov zoo ntawm qhov chaw tiav thiab nruj kam rau ua uas txo qis tshaj tom qab - ua lub sij hawm thiab cov khoom pov tseg. Txawm hais tias koj tab tom nrhiav 40CrNiMo alloy steel castings rau gearboxes, shafts, fasteners, lossis siab -load kis tau tus mob, peb cov txheej txheem poob wax casting ua kom zoo ib yam los ntawm thawj tsab xov xwm mus rau tag nrho cov khoom khiav.
Vim li cas 40CrNiMo?
Cov khoom ua tau zoo hais rau nws tus kheej. Nrog cov tshuaj muaj pes tsawg leeg ntawm cov pa roj carbon 0.37-0.44%, chromium 0.60-0.90%, nickel 1.25-1.65%, thiab molybdenum 0.15-0.25%, 40CrNiMo alloy steel xa cov khoom siv kho tshuab uas deb tshaj cov qib carbon steel. Tom qab kev kho cua sov kom zoo-feem ntau cov roj quenching ntawm 850℃tom qab tempering ntawm ib ncig ntawm 600℃-qhov kawg microstructure ua tempered sorbite, yielding:
| Khoom | Tus nqi |
| Tensile zog (σb) | Ntau dua lossis sib npaug li 980 MPa |
| Yield zog (σs) | Ntau dua lossis sib npaug li 835 MPa |
| Elongation (d 5) | Ntau dua lossis sib npaug li 12% |
| Ntu Shrinkage (ψ) | Ntau dua lossis sib npaug li 12% |
| Impact Toughness (Akv) | Ntau dua lossis sib npaug li 78 J |
| Hardness (HB) | 274–303 |
- Cov nuj nqis no sawv cev tiag tiag - qauv kev ua haujlwm hauv ntiaj teb, tsis yog qhov siab tshaj plaws theoretical. Cov ntsiab lus npib tsib xee siab ua kom muaj zog, thaum molybdenum txhim kho hardenability thiab txo cov temper embrittlement - tseem ceeb rau cov khoom uas dhau mus rau cyclic loading los yog ua hauj lwm nyob rau hauv lub fluctuating kub ib puag ncig
Txheej Txheem Zoo
Kev nqis peev casting muab kev ua siab ntev dua (CT5-CT7 ib ISO 8062, vs. CT8-CT10 rau xuab zeb casting) - ze li ± 0.10 hli ntawm qhov me me, slashing machining xav tau. Nto tiav yog nyob deb smoother: Ra 1.6-6.3 µm vs. xuab zeb casting's 12.5-50 µm, zoo tagnrho rau hydraulic lossis rotating Cheebtsam. Cov duab tsis yooj yim (cov phab ntsa nyias, undercuts, sab hauv) cam khwb cia li ib thooj, tsis muaj nqi ntxiv obs. Rau 40CrNiMo, sib sib zog nqus hardenability ua kom cov khoom sib xws txawm tias nyob rau hauv cov ntu tuab - qee yam qis dua - alloy steels tsis sib xws.
Daim ntawv thov thoob plaws kev lag luam
40CrNiMo peev cam khwb cia qhov chaw ua haujlwm xav tau lub luag haujlwm uas tsis ua haujlwm tsis yog qhov kev xaiv. Cov ntawv thov uas muaj xws li:
Automotive & Hnyav Trucks
Cov iav kis tau tus mob, cov khoom sib txawv, cov ncej qag, thiab siab - lub zog fasteners rau cov tsheb lag luam. Lub alloy qhov sib xyaw ua ke ntawm kev hnav tsis kam thiab kev cuam tshuam toughness ua rau nws tshwj xeeb tshaj yog haum rau cov khoom siv tsav tsheb uas yuav tsum muaj sia nyob ntau lab lub voj voog.
