60Si2Mn amabha ensimbi ayindilinga ashisayo agingqiwe

I-60Si2Mn spring steel iyinsimbi yasentwasahlobo ye-silico-manganese esetshenziswa kakhulu enamandla angaphezulu kancane, ukunwebeka nokuba lukhuni kune-55Si2Mn. Imboni yensimbi yasentwasahlobo engu-60Si2Mn ikhiqiza iziphethu eziyisicaba ezinomthwalo omkhulu noma iziphethu zamakhoyili ezinobubanzi obungaphansi kuka-30mm. Ifanele futhi ukwenza iziphethu ezikwazi ukumelana nokushisa ngesiphakathi esingagqwali esinezinga lokushisa elingaphansi kuka-250 °C futhi elinomthwalo oshintshanayo kanye nengcindezi ephezulu. Imithombo emikhulu yekhoyili ebalulekile yokusebenza ngaphansi, kanye nezinhlelo zokumunca ukushaqeka kwezimoto.

Ingxenye Yekhemikhali:

C(%)	Si(%)	Mn(%)	P(%)	S(%)	Cr(%)	I-Ni(%)	Cu(%)	I-yeld stress (Mpa)	I-tensile stress (Mpa)	Ubude (%)
0.56-0.64	1.5-2.0	0.6-0.9	≦0.035	≦0.035	≦0.35	≦0.35	≦0.35	≧1175	≧1275	≧5

Izakhiwo zemishini:

Amandla e-Tensile σb (MPa): ≥ 1274 (130)
Amandla esivuno σs (MPa): ≥1176 (120)
Ubude δ10 (%): ≥5
Ukuncipha kwendawo ψ (%): ≥25
Ukuqina: ukugoqa okushisayo, ≤321HB; umdwebo obandayo + ukwelashwa kokushisa, ≤321HB

Ukucaciswa kokushisa:

Ukucaciswa kokwelashwa kokushisa okungu-60Si2Mn: ukucisha i-870 °C ± 20 ° C, ukupholisa uwoyela; ukushisa okungu-480 ° C ± 50 ° C (kudingeka ngokukhethekile, ± 30 ° C).
Inhlangano ye-Metallographic: tempered troostite.

Isimo sokulethwa: Insimbi egoqelwe ngokushisayo ilethwa esimweni esiphethwe ukushisa noma esingashisi, futhi insimbi edonswa ngokubanda ilethwa esimweni esiphethwe ukushisa.
Ukucaciswa kokulethwa kwe-hot rolling: 2.0 ~ 18.0mm, kanye nangaphandle kwe-anneal. Ukucaciswa kokulethwa okugoqekayo okubandayo: 0.3 ~ 4.3mm (umcu wensimbi)

Indlela yokwelapha ukushisa

Izindlela zokwelashwa kokushisa ezingama-60Si2Mn ziwukushisa kwe-isothermal kanye nokunciphisa izinga lokushisa, ukucisha izinga lokushisa elingaphansi kanye nokushisa okuphezulu, inqubo yokwelapha ukushisa kwe-deformation. Indlela ingathuthukisa ngempumelelo amandla nempilo yesevisi ye-60Si2Mn spring steel. I-60Si2Mn ingeyensimbi yasentwasahlobo, ilungele ukwenza isiphethu samaqabunga emoto. I-60Si2Mn i-spring steel heat heat tempering ne-grade quenching, ukucisha izinga lokushisa elingaphansi kanye nokushisa okuphezulu, inqubo yokwelapha ukushisa kwe-deformation. Indlela ingathuthukisa ngempumelelo amandla nempilo yesevisi ye-60Si2Mn spring steel.

ukuminyana

60Si2Mn ukuminyana kuka-7.85g / cm3. I-60Si2Mn isetshenziswa kabanzi i-silicon manganese spring steel, amandla, ukunwebeka nokuba lukhuni kune-55Si2Mn ephakeme kancane. Ifanele izimoto zikaloliwe, imboni yezogandaganda yezimoto ukukhiqiza umthwalo omkhudlwana weziphethu eziyisicaba noma ucingo ububanzi obungama-30mm ngaphansi kwe-coil spring.
