4340 Pae hao UT hoao :
Hoʻomaʻamaʻa ʻia kā mākou 4340 alloy steel flat bar i ka hoʻāʻo ultrasonic ikaika (UT) e hōʻoia i ke kani o loko a me ka hale kīnā ʻole. Ke ʻike nei kēia ʻano hoʻāʻo hoʻopōʻino ʻole i nā discontinuities o loko e like me nā māwae, voids, a me nā inclusions i ʻike ʻole ʻia e ka maka. Hana ʻia ka nānā ʻana o UT e like me nā kūlana ʻoihana, e hōʻoia ana i kēlā me kēia pā e hoʻokō i nā koi kiʻekiʻe no ka aerospace, automotive, a me nā noi ʻenehana hana kaumaha. ʻO ka mana o ka maikaʻi hilinaʻi e hōʻoiaʻiʻo i ka hoʻoikaika ʻana i ke kūpaʻa luhi, ka paʻa o ke kūkulu ʻana, a me ka hilinaʻi o ka mea kūʻai aku.
4340 Alloy Bar PMI hoao :
No ka hōʻoia ʻana i ka traceability a me ka hoʻokō ʻana i nā kikoʻī o ka mea kūʻai aku, mālama ʻia ka hoʻokolohua PMI (Positive Material Identification) ma AISI 4340 Alloy Steel Flat Bars me ka hoʻohana ʻana i nā spectrometers kiʻekiʻe a i ʻole X-ray fluorescence (XRF). Hōʻoia kēia ʻano hoʻāʻo hoʻomake ʻole i ka hui kemika o kēlā me kēia helu wela, me ka hōʻoia ʻana e hoʻokō ʻo ia i nā pae hoʻohui i koi ʻia e like me Ni, Cr, a me Mo.
4340 Bar paakiki hoao :
No ka hōʻoia ʻana i ke ʻano o ka mālama ʻana i ka wela a hōʻoia i ka hana mechanical, e hoʻokō ʻia ka hoʻāʻo paʻakikī ma AISI 4340 Alloy Steel Flat Bars me ka hoʻohana ʻana i nā ala ʻo Rockwell a i ʻole Brinell. No nā kī kī i hoʻopau ʻia a hoʻomāinoino ʻia, ʻo ka laulā paʻakikī maʻamau he 24 a 38 HRC. Hoʻopaʻa ʻia nā waiwai paʻakikī ma nā wahi he nui ma ka ʻili a me ka ʻāpana keʻa e hōʻoia i ka lokahi. Kōkua nā hualoaʻa e hōʻoia i ke kūpono o ke kila no nā noi koi e pili ana i ke koʻikoʻi a me ka hopena.

Nā noi o AISI 4340 Alloy Bar
1.Aircraft Landing Gear Assemblies:
Hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana pae ʻāina e like me nā struts a me nā loulou, kahi o kona ikaika tensile kiʻekiʻe a me ke kūpaʻa e hōʻoia i ka hana hilinaʻi ma lalo o ke koʻikoʻi koʻikoʻi.
2. Pūnaehana Drivetrain Automotive:
Hoʻohana ʻia i ka hana ʻana i nā ʻāpana hoʻoili koʻikoʻi e like me nā gears a me nā shafts, hāʻawi ʻo AISI 4340 i ke kūpaʻa maikaʻi loa a me ka pono o ka hana i nā kaʻa kaʻa kiʻekiʻe.
3.Forged Hydraulic System Parts:
Koho ʻia no nā noi ʻōnaehana hydraulic, ʻoi aku ka maikaʻi o kēia huila i ke kū ʻana i ke kaomi a me ka haʻalulu mechanical, kūpono ia no nā piston hydraulic forged, cylinders, a me nā mea pono.
4. High-Performance Engine Crankshafts:
Manaʻo ʻia no ka hana ʻana i ka crankshaft i nā mīkini hana kiʻekiʻe, ʻo kona ikaika luhi a me ka paʻakikī e hōʻoia i ka lōʻihi o ka lawelawe ʻana ma lalo o ka hoʻouka ʻana.
5.Industrial Power Transmission Components:
Hoʻohana ʻia i ke kūkulu ʻana i nā mea hana koʻikoʻi a me nā kumu no nā mea hoʻoili mana, kahi e kūʻē ai i ka lole a me ka deformation i ke koi ʻana i nā ʻōnaehana mechanical.
No ke aha e koho ai iā mākou?
•Hiki iā ʻoe ke loaʻa ka mea kūpono e like me kāu koi ma ka liʻiliʻi loa o ke kumu kūʻai.
•Hāʻawi pū mākou i nā Reworks, FOB, CFR, CIF, a me nā kumukūʻai hoʻopuka puka i ka puka. Manaʻo mākou iā ʻoe e hana i ka hana no ka hoʻouna ʻana e ʻoi aku ka waiwai.
•Hiki ke hōʻoia ʻia nā mea a mākou e hāʻawi ai, mai ka palapala hōʻike maka a hiki i ka ʻōlelo kikoʻī hope. (E hōʻike ʻia nā hōʻike ma ke koi)
•Ke hōʻoiaʻiʻo nei mākou e hāʻawi i kahi pane i loko o 24 mau hola (maʻamau i ka hola hoʻokahi)
•Hāʻawi i ka hōʻike SGS TUV.
•Hoʻolaʻa piha mākou i kā mākou mea kūʻai. 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 mea kūʻai aku.
•Hāʻawi i ka lawelawe hoʻokahi.
High Tensile Steel Flat 4340 Pākuʻi:
1. He mea koʻikoʻi ka hoʻopaʻa ʻana ma ka hihia o ka hoʻouna ʻana i ka honua kahi e hele ai ka lawe ʻana ma nā ala like ʻole e hiki ai i ka hopena hope loa, no laila ke kau nei mākou i ka hopohopo kūikawā e pili ana i ka ʻeke.
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,
