40CrNiMo Steel Round Bar

40CrNiMo yotentha yozungulira zitsulo zozungulira

Chitsulo cha 40CrNiMoA ndi chitsulo cha alloy cha China, chili ndi mphamvu zambiri, kulimba komanso kulimba kwabwino, ndipo chimakhala chokhazikika chotsutsana ndi kutentha, koma chimakhala ndi mphamvu zoyera kwambiri, kupsa mtima komanso kusasunthika bwino. Kutentha kumafunika musanayambe kuwotcherera, ndipo chithandizo chothandizira kuchepetsa nkhawa chimafunika pambuyo pa kuwotcherera.

Chiyambi cha malonda

Chitsulo cha 40CrNiMoA chimagwiritsidwa ntchito pambuyo pozimitsa ndi kutentha, ndipo chimagwiritsidwa ntchito popanga zigawo zofunika zomwe zimafuna pulasitiki yabwino, mphamvu zazikulu ndi kukula kwakukulu. Mwachitsanzo, ma shafts olemetsa m'makina olemetsa, ma turbine shafts okhala ndi mainchesi akulu kuposa 250 mm, masamba, ma transmissions, fasteners, crankshafts, magiya, ndi zina zotere, zitha kugwiritsidwanso ntchito popangira ma rotor shafts ndi masamba omwe akugwira ntchito pa kutentha kopitilira 400. °C.
Chrome-Moly low alloy steel series ili ndi 0.5% - 9% Cr ndi 0.5% - 1% Mo ndi pansi kuposa 0.20% carbon. 40CrNiMoA, 4340 ndi SNCM439 ndi otsika aloyi chromoly zitsulo zipangizo kuchokera pa mfundo zosiyanasiyana.

4340 ndi SNCM439 ndi miyezo yochokera ku America ndi Japan motsatana. Nthawi zambiri amatha kukhala zida zina, pokhapokha ngati pali cholembera chapadera kapena chogwiritsidwa ntchito mwapadera. Kusiyana kwawo kumapezeka makamaka muzinthu zamakina, tsatanetsatane wawonetsedwa motere:

Kutentha Kutentha: 600 ° C (Quenchant- madzi, mafuta)

Amagwiritsidwa ntchito pomwe pamafunika zida zolimba kwambiri komanso zolimba kuti zisavale bwino monga ma axle olemera kwambiri, ma shaft, magiya olemetsa, masipingo, ma pin, ma bolt, ma couplings, sprockets, pinions, torsion bars, zolumikizira. Zitsulo zamtundu wa alloy zakhala zikugwiritsidwa ntchito kwambiri m'malo monga mafakitale amafuta amafuta, magalimoto, zida zamagetsi zamagetsi ndi ntchito zina zotentha kwambiri.
