Ngā āhuatanga pūkaha:
Te pakari σb (MPa): ≥ 1274 (130)
Te kaha tuku σs (MPa): ≥1176 (120)
Whakaroa δ10 (%): ≥5
Te whakahekenga rohe ψ (%): ≥25
Te pakeke: te huri wera, ≤321HB; tuhi makariri + maimoatanga wera, ≤321HB
Whakatakotoranga wera:
60Si2Mn tohu maimoatanga wera: tinei 870 °C ± 20 ° C, te whakamahana hinu; te whakamahana 480 ° C ± 50 ° C (e hiahiatia ana, ± 30 ° C).
Te whakahaere Metallographic: tempered troostite.
Te mana tuku: Ka tukuna te tira wera-wera i roto i te wera-wera, i te kore-wera ranei, ka tukuna te rino makariri i roto i te ahua o te wera.
Ko nga korero tuku mo te hurihanga wera: 2.0 ~ 18.0mm, me te kore o te annealing. Whakatakotoranga tuku okeoke matao: 0.3~4.3mm (horoi maitai)
Tikanga maimoatanga wera
Ko nga tikanga maimoatanga wera 60Si2Mn ko te whakamaarama i te waariki me te whakamaarama tohu, te whakamaarama iti-te wera me te whakamaarama teitei o te wera, te tukanga maimoatanga wera rereke. Ka taea e te tikanga te whakapai ake i te kaha me te oranga o te 60Si2Mn puna maitai. Ko te 60Si2Mn no te puna maitai, e tika ana mo te hanga puna rau motika. 60Si2Mn puna maitai maimoatanga wera whakamahana hauhautanga me te whakamaarama karaehe, te tiini iti-mahana me te whakamahana teitei o te wera, te tukanga maimoatanga wera deformation. Ka taea e te tikanga te whakapai ake i te kaha me te oranga o te 60Si2Mn puna maitai.
kiato
60Si2Mn kiato o 7.85g / cm3. Ko te 60Si2Mn e whakamahia nuitia ana te silicon manganese puna maitai, te kaha, te elasticity me te pakeke atu i te 55Si2Mn paku teitei ake. He pai mo nga waka tereina, he umanga tarakihana motokoto kia nui ake te uta o nga puna papatahi, te diameter waea ranei o te 30mm i raro i te puna coil.
