16MnCr5 Alloy Steel Forging Gears e nang le CNC Machining

Kenyelletso ea lintho tse bonahalang

16MnCr5 alloy steel, tšepe ea boleng bo holimo e tlase e tsoang Jeremane, e tsejoa e le moemeli oa tšepe e sebetsang hantle haholo. Chaena, hangata e bitsoa 16CrMnH (ho ea ka GB/T 5216-2004 standard). Boitsebiso bona bo nkile sebaka tšimong ea maemo a holimoli-gear castingstlhahiso ka lebaka la ts'ebetso ea eona e ntle ea carburizing, ho thatafala haholo le machinability e ntle. Kamora kalafo ea carburizing le ho tima, boima ba bokaholimo ba 16MnCr5metsoako ea tšepe ea motsoakoe ntlafalitsoe haholo mme ho hanyetsa ho roala ho matlafatsoa haholo. Ke khetho e nepahetseng bakeng sa ho etsa likarolo tse jereng meroalo e boima le likhohlano khafetsa.

Sebopeho sa lik'hemik'hale le microstructure

Sebopeho sa lik'hemik'hale sa 16MnCr5 alloy steel se arotsoe ka hloko ho netefatsa thepa ea eona e metle ea mochini:
C: 0,14% ~ 0,19%, ho fana ka matla a hlokahalang le boima ba tšepe.
Si: ≤0.40%, e thusa ho ntlafatsa botsitso ba mocheso le khanyetso ea oxidation ea tšepe.
Mn: 1.00% ~ 1.30%, e ntlafatsa ho thatafala le ho tiea ha tšepe.
Cr: 0.80% ~ 1.10%, e ntlafatsa haholo ho hanyetsa kutu le ho roala ho hanyetsa ha tšepe.
S: ≤0.035%, e laola mocheso oa brittleness oa tšepe.
P: ≤0.035%, e ntlafatsa matla le ho hanyetsa mocheso oa sepakapaka oa tšepe.

Thepa ea mechine

16MnCr5 alloy steel e na le thepa e ntle ea mochini mme e ka fihlela litlhoko tsa lits'ebetso tse thata tsa indasteri:
Matla a matla (MPa): 880-1180, ho netefatsa botsitso ba likarolo ha li le tlas'a matla a maholo a thata.
Matla a tlhahiso ea maemo (MPa): hangata ho pota 635 (boleng bo ikhethileng bo ka fapana ho latela ts'ebetso ea kalafo ea mocheso), ho netefatsa hore thepa e jara matla pele e hlahisa.
Elongation (%): 9, e bontšang hore thepa e na le polasetiki e ntle 'me ha e bonolo ho robeha ha e qobelloa.
Phokotso ea likarolo (%): 57 (kapa 35, ho latela maemo a tlhahlobo le boholo ba mohlala), e bonts'ang matla a ho monya matla pele a robeha.
Matla a amang (J/cm²): 34, e bonts'ang ho tiea ha thepa ha e le tlas'a tšusumetso.
Ho thatafala: ≤297 HB, ho fana ka motheo o motle bakeng sa phekolo e latelang ea carburizing le quenching.
