16MnCr5 Alloy Karfe Forging Gears tare da CNC Machining

Gabatarwar kayan abu

16MnCr5 gami karfe, wani babban inganci low gami karfe samo asali daga Jamus, da aka sani da wakilin high-yi kaya karfe. A kasar Sin, ana kiranta sau da yawa 16CrMnH (bisa ga GB/T 5216-2004 misali). Wannan abu ya shagaltar da wani wuri a fagen high-karshenkayan wasan kwaikwayomasana'antu saboda kyakkyawan aikin carburizing, kyakkyawan ƙarfin ƙarfi da machinability mai kyau. Bayan carburizing da quenching magani, taurin saman 16MnCr5gami karfe forgingsyana inganta sosai kuma ana haɓaka juriya sosai. Zabi ne mai kyau don ƙera sassan da ke ɗaukar kaya masu nauyi da yawan juzu'i.

Abubuwan sinadaran da microstructure

Abubuwan sinadaran 16MnCr5 gami da karfe an daidaita su a hankali don tabbatar da kyawawan kaddarorin injin sa:
C: 0.14% ~ 0.19%, yana ba da ƙarfin da ake bukata da taurin karfe.
Si: ≤0.40%, yana taimakawa wajen inganta kwanciyar hankali na thermal da juriya na iskar shaka na karfe.
Mn: 1.00% ~ 1.30%, yana haɓaka ƙarfin ƙarfi da taurin ƙarfe.
Cr: 0.80% ~ 1.10%, yana inganta haɓaka juriya da juriya na ƙarfe.
S: ≤0.035%, sarrafa thermal brittleness na karfe.
P: ≤0.035%, inganta ƙarfi da juriya ga lalata yanayi na karfe.

Kayan aikin injiniya

16MnCr5 gami karfe yana da kyawawan kayan aikin injiniya kuma yana iya saduwa da buƙatun aikace-aikacen masana'antu masu ƙarfi:
Ƙarfin Ƙarfin Ƙarfi (MPa): 880-1180, yana tabbatar da kwanciyar hankali na sassa lokacin da aka yi amfani da karfi mai girma.
Ƙarfin yawan amfanin ƙasa (MPa): yawanci a kusa da 635 (ƙimar ƙayyadaddun ƙila na iya bambanta dangane da tsarin kula da zafi), yana tabbatar da ƙarfin ɗaukar kayan kafin samarwa.
Tsawaitawa (%): 9, yana nuna cewa kayan yana da filastik mai kyau kuma ba shi da sauƙin karya lokacin da aka yi masa ƙarfi.
Rage sashe (%): 57 (ko 35, ya danganta da yanayin gwaji da girman samfurin), yana nuna ƙarfin ɗaukar kuzarin kayan kafin karyawa.
Ƙimar taurin tasiri (J/cm²): 34, yana tabbatar da taurin kayan lokacin da aka yi tasiri.
Taurin: ≤297 HB, yana ba da tushe mai kyau don ci gaban carburizing da quenching jiyya.
