16MnCr5 Alloy Steel Forging Gears ine CNC Machining

Sumo yenyaya

16MnCr5 alloy simbi, yemhando yepamusoro yakaderera alloy simbi inobva kuGermany, inozivikanwa semumiriri wepamusoro-inoshanda giya simbi. MuChina, inowanzonzi 16CrMnH (maererano neGB/T 5216-2004 standard). Nyaya iyi yakatora nzvimbo mumunda wepamusoro-sorogear castingskugadzira nekuda kwekuita kwayo kwakanakisa carburizing, kuomarara kwakanyanya uye kunaka machinability. Mushure mekuvhara uye kudzima kurapwa, kuomarara kwepamusoro kwe16MnCr5alloy simbi forgingsinovandudzwa zvakanyanya uye kuramba kupfeka kunowedzerwa zvakanyanya. Iyo isarudzo yakanaka yekugadzira zvikamu zvinotakura zvinorema uye zvinogara zvichikweshana.

Kemikari yakagadzirwa uye microstructure

Iyo kemikari inoumbwa ye16MnCr5 alloy simbi yakave yakanyatso kuenzanirana kuti ive nechokwadi chayo chemhando yepamusoro michina:
C: 0.14% ~ 0.19%, kupa simba rinodiwa uye kuoma kwesimbi.
Si: ≤0.40%, inobatsira kuvandudza kugadzikana kwekupisa uye oxidation kuramba kwesimbi.
Mn: 1.00% ~ 1.30%, inowedzera kuoma uye kuoma kwesimbi.
Cr: 0.80% ~ 1.10%, inonyanya kunatsiridza kusimba kwekuora uye kupfeka kuramba kwesimbi.
S: ≤0.035%, inodzora brittleness yekupisa kwesimbi.
P: ≤0.035%, inovandudza simba uye kurwisana nemhepo inopisa yesimbi.

Mechanical properties

16MnCr5 alloy simbi ine yakanakisa mechaniki zvivakwa uye inogona kusangana nezvinodiwa zvekuomesera maindasitiri maapplication:
Kusimba kwesimba (MPa): 880-1180, kuve nechokwadi kugadzikana kwezvikamu kana zvichiiswa pasi pemasimba makuru ekumanikidza.
Conditional goho simba (MPa): kazhinji kutenderedza 635 (iyo chaiyo kukosha inogona kusiyanisa zvichienderana nekupisa kurapwa maitiro), kuve nechokwadi chekuti zvinhu zvinotakura mutoro usati wabereka.
Elongation (%): 9, zvichiratidza kuti zvinhu zvine purasitiki yakanaka uye haisi nyore kuputsika kana ichimanikidzwa.
Kudzikisira kwechikamu (%): 57 (kana makumi matatu neshanu, zvichienderana nemamiriro ekuyedzwa uye saizi yemuenzaniso), inoratidza simba rekunyudza simba rechinhu risati rapwanyika.
Impact kuoma kukosha (J/cm²): 34, zvichiratidza kuoma kwechinhu kana ichinge yakanganiswa.
Kuoma: ≤297 HB, ichipa hwaro hwakanaka hwekuzotevera carburizing uye kudzima kurapwa.
