Litšepe tse chitja tse 60Si2Mn tse chesang

60Si2Mn spring steel ke tšepe e sebelisoang haholo ea silico-manganese ea selemo e nang le matla a seng makae, elasticity le thata ho feta 55Si2Mn. Indasteri ea tšepe ea selemo ea 60Si2Mn e hlahisa liliba tse bataletseng tse nang le meroalo e meholo kapa liliba tsa coil tse bophara bo ka tlase ho 30mm. E boetse e loketse ho etsa liliba tse thibelang mocheso ka mokhoa o sa senyeng o nang le mocheso o sebetsang o ka tlase ho 250 ° C mme o na le mojaro o fapaneng le khatello e phahameng ea maikutlo. Liliba tse kholo tsa bohlokoa tsa li-coil bakeng sa ho sebetsa ka tlase, hammoho le litsamaiso tsa ho monya ho ts'oenyeha ha likoloi.

Lintho tsa mochini:

Matla a ho tiisa σb (MPa): ≥ 1274 (130)
Matla a tlhahiso σs (MPa): ≥1176 (120)
Elongation δ10 (%): ≥5
Ho fokotseha ha sebaka ψ (%): ≥25
Ho thatafala: ho bilika ho chesang, ≤321HB; setšoantšo se batang + phekolo ea mocheso, ≤321HB

Tlhaloso ea mocheso:

Tlhaloso ea phekolo ea mocheso oa 60Si2Mn: ho tima 870 °C ± 20 ° C, ho pholile ha oli; ho futhumatsa 480 ° C ± 50 ° C (ho hlokahala ka ho khetheha, ± 30 ° C).
Mokhatlo oa Metallographic: tempered troostite.

Boemo ba ho pepa: Litšepe tse chesang tse chesang li fanoa ka mocheso oa mocheso kapa o sa chesoeng ke mocheso, 'me litšepe tse huloang ke serame li fanoa ka mocheso oa mocheso.
Litlhaloso tsa ho fana ka li-rolling tse chesang: 2.0 ~ 18.0mm, ka ntle le ho annealing. Litlhaloso tsa ho tsamaisa tse batang: 0.3 ~ 4.3mm (sethapo sa tšepe)

Mokhoa oa phekolo ea mocheso

60Si2Mn mekhoa ea phekolo ea mocheso ke mocheso oa isothermal le ho tima likhalase, ho tima mocheso o ka tlaase ho mocheso le mocheso o phahameng oa mocheso, mokhoa oa ho phekola mocheso oa deformation. Mokhoa ona o ka ntlafatsa ka katleho matla le bophelo ba tšebeletso ea 60Si2Mn tšepe ea selemo. 60Si2Mn ke ea tšepe ea selemo, e loketseng ho etsa selemo sa makhasi a koloi. 60Si2Mn mocheso oa tšepe oa mocheso oa mocheso oa mocheso oa mocheso oa mocheso le ho tima likhalase, ho tima mocheso o ka tlase ho mocheso le mocheso o phahameng oa mocheso, mokhoa oa ho phekola mocheso oa deformation. Mokhoa ona o ka ntlafatsa ka katleho matla le bophelo ba tšebeletso ea 60Si2Mn tšepe ea selemo.

tekano

60Si2Mn boima ba 7.85g / cm3. 60Si2Mn e sebelisoa haholo silicon manganese spring tšepe, matla, elasticity le hardability ho feta 55Si2Mn holimo hanyenyane. E loketse likoloi tsa terene, indasteri ea terekere ea likoloi ho hlahisa mojaro o moholo oa liliba tse bataletseng kapa bophara ba terata ba 30mm ka tlase ho seliba sa coil.
