45 # otentha adagulung'undisa zitsulo pepala

Njira yopangira kutentha kwazitsulo za 45 zotchulidwa muyeso ya GB/T699-1999 ndizokhazikika pa 850 ° C, kuzimitsa pa 840 ° C, ndi kutentha kwa 600 ° C. Kuchita bwino ndi mphamvu zokolola ≥355MPa
Muyezo wa GB/T699-1999 umanena kuti mphamvu yachitsulo ya 45 ndi 600MPa, mphamvu yokolola ndi 355MPa, elongation rate ndi 16%, ndipo kuchepetsa dera ndi 40%.
Kugwiritsa ntchito
No. 45 zitsulo chimagwiritsidwa ntchito makina, pamene si kutentha mankhwala: HB≤229; kutentha mankhwala: normalizing; mphamvu yamphamvu: Aku≥39J; mphamvu yayikulu, pulasitiki yabwino komanso kulimba, 45# mbale yachitsulo itatha kuzimitsa popanda kutenthetsa, kuuma kwake ndi kwakukulu kuposa HRC55 (Mpaka HRC62) ndiyoyenerera. Pambuyo pa chithandizo cha kutentha ndi kutentha, imatha kufika ku HRC42-46, yomwe siingangotsimikizira kuti ili ndi makina abwino, komanso kupeza zofunikira za kuuma kwa pamwamba. Amagwiritsidwa ntchito popanga zosintha zazing'ono zomwe zimatha kupirira katundu wokulirapo. Zigawo zabwino kwambiri ndi zigawo zazikulu zokhazikika zokhala ndi kupsinjika pang'ono, komanso zida zolimba zomwe sizifuna mphamvu yayikulu, monga maupangiri, zolemba zowongolera, manja owonera ndi zigawo zina.

Zimango katundu

Zowoneka za C45 zitsulo

1, Chitsulo chapakati cha carbon

2, High mphamvu ndi machinability

3, kulimba kwabwino, pulasitiki komanso kukana abrasion

4, Amagwiritsidwa ntchito pozimitsidwa ndi kupsya mtima kapena kukhazikika

4, Mapulogalamu Okhazikika

1, Amagwiritsidwa ntchito kwambiri popanga makina

2, Zazigawo za shaft

3, Kukonza zida zojambulira zida zakufa ndikuzimitsa
