60Si2Mn yotentha yozungulira zitsulo zozungulira

60Si2Mn spring steel ndi chitsulo chogwiritsidwa ntchito kwambiri cha silico-manganese chomwe chili ndi mphamvu zokwera pang'ono, zolimba komanso zolimba kuposa 55Si2Mn. Makampani azitsulo a 60Si2Mn amatulutsa akasupe athyathyathya okhala ndi katundu wamkulu kapena akasupe a koyilo okhala ndi mainchesi osakwana 30mm. Ndiwoyeneranso kupanga akasupe osamva kutentha okhala ndi sing'anga yosawononga ndi kutentha kogwira ntchito pansi pa 250 ° C komanso mosinthasintha komanso kupsinjika kwakukulu. Akasupe akuluakulu opangira ma coil ogwirira ntchito pansi, komanso makina amayamwidwe owopsa pamagalimoto.

Chemical Component:

Makaniko katundu:

Kulimba kwamphamvu σb (MPa): ≥ 1274 (130)
Mphamvu zokolola σs (MPa): ≥1176 (120)
Elongation δ10 (%): ≥5
Kuchepa kwadera ψ (%): ≥25
Kuuma: kutentha kugudubuza, ≤321HB; kujambula kozizira + chithandizo cha kutentha, ≤321HB

Kafotokozedwe ka kutentha:

60Si2Mn kutentha mankhwala specifications: kuzimitsa 870 °C ± 20 ° C, kuzirala mafuta; kutentha 480 ° C ± 50 ° C (makamaka, ± 30 ° C).
Bungwe la Metallographic: tempered troostite.

Mkhalidwe wotumizira: Zitsulo zotentha zimaperekedwa mu kutentha kwa kutentha kapena kusatenthedwa, ndipo zitsulo zozizira zimaperekedwa mu kutentha kwa kutentha.
Hot anagubuduza yobereka specifications: 2.0 ~ 18.0mm, ndi popanda annealing. Zoziziritsa kutulutsa zoziziritsa kuzizira: 0.3 ~ 4.3mm (mzere wachitsulo)

Njira yochizira kutentha

Njira zochizira kutentha kwa 60Si2Mn ndi kutentha kwa isothermal ndi kuzimitsa kutentha, kuzimitsa kutentha pang'ono komanso kutentha kwambiri, njira yochiritsira kutentha. Njirayi imatha kupititsa patsogolo mphamvu ndi moyo wautumiki wa 60Si2Mn masika zitsulo. 60Si2Mn ndi yachitsulo chakumapeto, choyenera kupanga masika amasamba agalimoto. 60Si2Mn masika zitsulo kutentha kutentha isothermal tempering ndi grading quenching, sub-kutentha kuzimitsidwa ndi kutentha kutentha, mapindikidwe kutentha kutentha ndondomeko. Njirayi imatha kupititsa patsogolo mphamvu ndi moyo wautumiki wa 60Si2Mn masika zitsulo.

kachulukidwe

Kuchuluka kwa 60Si2Mn kwa 7.85g / cm3. 60Si2Mn imagwiritsidwa ntchito kwambiri silicon manganese masika chitsulo, mphamvu, elasticity ndi hardability kuposa 55Si2Mn apamwamba pang'ono. Oyenera magalimoto njanji, galimoto thirakitala makampani kupanga katundu wokulirapo wa akasupe lathyathyathya kapena waya awiri a 30mm pansi koyilo kasupe.
