16MnCr5 Alloy Steel Forging Gears me CNC Machining

Mea hoʻolauna

ʻO ke kila kila 16MnCr5, he kila kila haʻahaʻa haʻahaʻa kiʻekiʻe mai Kelemānia mai, ʻike ʻia ʻo ia ka ʻelele o ke kila kila kiʻekiʻe. Ma Kina, kapa pinepine ʻia ʻo 16CrMnH (e like me ka maʻamau GB / T 5216-2004). Ua noho kēia mea i kahi wahi ma ke kula kiʻekiʻenā mea hoʻolei ʻanaka hana ʻana ma muli o kāna hana carburizing maikaʻi loa, hardenability maikaʻi a me ka machinability maikaʻi. Ma hope o ka carburizing a me ke kinai ʻana i ka mālama ʻana, ʻo ka paʻakikī o ka ʻili o 16MnCr5nā mea hao haoua hoʻomaikaʻi nui ʻia a ua hoʻonui nui ʻia ke kūpaʻa ʻaʻahu. He koho maikaʻi loa ia no ka hana ʻana i nā ʻāpana e amo i nā ukana kaumaha a me ka hakakā pinepine.

ʻO ka haku melemele a me ka microstructure

Ua hoʻohālikelike pono ʻia ka hui kemika o ke kila kila 16MnCr5 e hōʻoia i kona mau waiwai mechanical maikaʻi loa:
C: 0.14% ~ 0.19%, hāʻawi i ka ikaika a me ka paʻakikī e pono ai no ke kila.
ʻO Si: ≤0.40%, kōkua i ka hoʻomaikaʻi ʻana i ke kūpaʻa wela a me ka pale ʻana o ke kila.
Mn: 1.00% ~ 1.30%, hoʻonui i ka paʻakikī a me ka paʻakikī o ke kila.
Cr: 0.80% ~ 1.10%, hoʻomaikaʻi nui i ka pale ʻana i ka corrosion a me ka pale ʻana i ke kila.
S: ≤0.035%, hoʻomalu i ka brittleness thermal o ke kila.
P: ≤0.035%, hoʻomaikaʻi i ka ikaika a me ke kū'ē ʻana i ka corrosion o ke kila.

ʻO 16MnCr5 ke kila kila maikaʻi loa a hiki ke hoʻokō i nā pono o nā noi ʻoihana ikaika:
Ka ikaika tensile (MPa): 880-1180, e hōʻoiaʻiʻo ana i ka paʻa o nā ʻāpana i ka wā i hoʻokau ʻia i nā ikaika tensile nui.
ʻO ka ikaika hoʻohua kūlana (MPa): ma kahi o 635 (e ʻokoʻa paha ke kumukūʻai kikoʻī ma muli o ke kaʻina hana mālama wela), e hōʻoia ana i ka hiki ke amo o ka mea ma mua o ka hāʻawi ʻana.
Elongation (%): 9, e hōʻike ana he maikaʻi ka plasticity a ʻaʻole maʻalahi ke wāwahi i ka wā e hoʻokau ʻia ai ka ikaika.
Hoʻemi ʻāpana (%): 57 (a i ʻole 35, e pili ana i nā kūlana hoʻāʻo a me ka nui o nā mea hoʻohālike), e hōʻike ana i ka hiki ke komo i ka ikehu o ka mea ma mua o ka haki ʻana.
Waiwai oolea hopena (J/cm²): 34, e hooiaio ana i ka paakiki o ka mea i ka hopena.
ʻO ka paʻakikī: ≤297 HB, e hāʻawi ana i kahi kumu maikaʻi no ka carburizing a me ka hoʻopau ʻana i ka mālama ʻana.
