ʻO ka pā pālahalaha kila kila AISI 4340 | Mea hoʻolako kila kila kila haʻahaʻa ikaika kiʻekiʻe
Wehewehe Pōkole:
ʻO ka AISI 4340 Alloy Steel Flat Bar kahi kila kila haʻahaʻa kiʻekiʻe i kaulana no kona paʻakikī kiʻekiʻe, ka ikaika tensile kiʻekiʻe, a me ke kūpaʻa maikaʻi loa i ka ʻaʻahu. Loaʻa iā ia ka nickel, chromium, a me ka molybdenum, kūpono kēia kila kila no nā noi e pono ai ka ikaika luhi kiʻekiʻe a me ke kūpaʻa i ka hopena.
4340 Pā pālahalaha kila kila:
ʻO ka pā pālahalaha kila kila AISI 4340he huahana kila palahalaha ikaika kiʻekiʻe, haʻahaʻa-alloy i kaulana no kona paʻakikī maikaʻi loa, paʻakikī hohonu, a me ke kūpaʻa i ka ʻaʻahu a me ka luhi. ʻIke nui ʻia ʻo 34CrNiMo6, 1.6582, a i ʻole 817M40 ma nā kūlana honua, loaʻa i kēia alloy ka nickel, chromium, a me ka molybdenum, e kūpono ana no nā noi hana kaumaha. Hoʻohana nui ʻia ia i nā ʻoihana aerospace, automotive, a me nā pūʻali koa no ka hana ʻana i nā crankshafts, axles, nā ʻāpana gear, a me nā ʻāpana kūkulu e koi ana i ke kūpaʻa hopena kiʻekiʻe a me ke ola lawelawe lōʻihi.

Hoʻāʻo UT Steel Bar 4340:
Hoʻomaʻamaʻa ʻia kā mākou mau kaola pālahalaha kila 4340 i ka hoʻāʻo ultrasonic koʻikoʻi (UT) e hōʻoia i ke kūpaʻa kūloko a me ke ʻano kīnā ʻole. ʻIke kēia ʻano hoʻāʻo ʻole e luku i nā discontinuities kūloko e like me nā māwae, nā hakahaka, a me nā hoʻokomo i ʻike ʻole ʻia e ka maka ʻōlohelohe. Hana ʻia ka nānā ʻana o UT e like me nā kūlana ʻoihana, e hōʻoia ana e hoʻokō kēlā me kēia kaola i nā koi hana kiʻekiʻe no nā noi ʻenekinia aerospace, automotive, a me nā hana kaumaha. Hōʻoia ka mana hoʻomalu maikaʻi hilinaʻi i ka pale ʻana i ka luhi, ka pono o ke kūkulu ʻana, a me ka hilinaʻi o ka mea kūʻai aku.
Hoʻāʻo PMI o ka Alloy Bar 4340:
I mea e hōʻoia ai i ka hiki ke hahai ʻia nā mea a me ke kūlike me nā kikoʻī o ka mea kūʻai aku, hana ʻia ka hoʻāʻo ʻana o ka PMI (Positive Material Identification) ma nā AISI 4340 Alloy Steel Flat Bars me ka hoʻohana ʻana i nā spectrometers holomua a i ʻole nā mea kālailai fluorescence X-ray (XRF). Hōʻoia kēia ʻano hoʻāʻo ʻole e luku i ka haku mele kemika o kēlā me kēia helu wela, e hōʻoia ana ua hoʻokō ia i nā pae element alloying i koi ʻia e like me Ni, Cr, a me Mo.

Nā noi o ka AISI 4340 Alloy Bar
1.Nā ʻAhahui Lako Pae Mokulele:
Hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana kapa pae e like me nā struts a me nā linkages, kahi e hōʻoia ai kona ikaika tensile kiʻekiʻe a me ke kūpaʻa i ka hana hilinaʻi ma lalo o ke kaumaha koʻikoʻi.
2. Nā ʻōnaehana hoʻokele kaʻa:
Hoʻohana ʻia i ka hana ʻana o nā ʻāpana hoʻoili koʻikoʻi e like me nā kia a me nā ʻauamo, hāʻawi ʻo AISI 4340 i ka lōʻihi maikaʻi loa a me ka pono hana i nā wahi kaʻa ukana kiʻekiʻe.
3. Nā ʻāpana ʻōnaehana hydraulic i hoʻopaʻa ʻia:
I koho ʻia no nā noi ʻōnaehana hydraulic, ʻoi aku ka maikaʻi o kēia metala i ke kū ʻana i ke kaomi a me ka haʻalulu mechanical, e kūpono ai no nā pistons hydraulic forged, cylinders, a me nā mea hoʻopili.
4. Nā Crankshafts ʻenekini hana kiʻekiʻe:
Makemake ʻia no ka hana ʻana o crankshaft i nā ʻenekini hana kiʻekiʻe, ʻo kona ikaika luhi a me ka paʻakikī kupaianaha e hōʻoiaʻiʻo i ke ola lawelawe lōʻihi ma lalo o ka hoʻouka cyclic.
5. Nā ʻĀpana Hoʻoili Mana ʻOihana:
Hoʻohana ʻia i ke kūkulu ʻana i nā kia kaumaha a me nā ʻau no nā lako hoʻoili mana, kahi e kūʻē ai i ka ʻaʻahu a me ka deformation i nā ʻōnaehana mechanical koi.
No ke aha e koho ai iā mākou?
•Hiki iā ʻoe ke loaʻa i ka mea kūpono e like me kāu koi ma ke kumu kūʻai haʻahaʻa loa.
•Hāʻawi pū mākou i nā kumukūʻai hoʻouna Reworks, FOB, CFR, CIF, a me ka puka a puka. Manaʻo mākou e hana ʻoe i kahi ʻaelike no ka hoʻouna ʻana i mea hoʻokele waiwai loa.
•Hiki ke hōʻoia piha ʻia nā mea a mākou e hāʻawi nei, mai ka palapala hōʻoia hoʻāʻo mea maka a hiki i ka ʻōlelo hope loa o ka dimensional. (E hōʻike ʻia nā hōʻike ma ke koi)
•Hoʻohiki mākou e hāʻawi i kahi pane i loko o 24 mau hola (maʻamau i ka hola hoʻokahi)
•Hāʻawi i ka hōʻike SGS TUV.
•Ua hoʻolaʻa piha mākou i kā mākou mea kūʻai aku. Inā ʻaʻole hiki ke hoʻokō i kāu mau koi ma hope o ka nānā ʻana i nā koho āpau, ʻaʻole mākou e alakaʻi hewa iā ʻoe ma ka hana ʻana i nā ʻōlelo hoʻohiki wahaheʻe e hoʻokumu ai i nā pilina maikaʻi me nā mea kūʻai aku.
•Hāʻawi i ka lawelawe hoʻokahi.
ʻO ke kila kiʻekiʻe tensile 4340 ka hoʻopili ʻana:
1. He mea nui loa ka hoʻopili ʻana, ʻoiai hoʻi i nā ukana o ka honua kahi e hele ai nā ukana ma nā ʻano like ʻole e hiki ai i kahi i manaʻo nui ʻia, no laila ke kau nei mākou i ka manaʻo nui e pili ana i ka hoʻopili ʻana.
2. Hoʻopili ʻo Saky Steel i kā mākou waiwai ma nā ʻano he nui e pili ana i nā huahana. Hoʻopili mākou i kā mākou huahana ma nā ʻano he nui, e like me,
