SAE 4140 4130 Na Kaola Poʻa Poʻa 4140 Paʻa hao
hiki iā mākou ke hāʻawi i nā mea maikaʻi maikaʻi, ka wikiwiki a me ke kōkua mea kūʻai maikaʻi loa.ʻO kā mākou huakaʻi ʻo "Hele mai ʻoe i ʻaneʻi me ka paʻakikī a hāʻawi mākou iā ʻoe i kahi ʻakaʻaka e lawe aku" no SAE 4140 4130 Carbon Steel Round Bars 4140 Steel bar, I kēia manawa, ke ʻimi nei mākou i mua i ka launa pū ʻana me nā ʻāina ʻē i hoʻoholo ʻia e nā pōmaikaʻi like.E ʻoluʻolu e ʻoluʻolu e launa pū me mākou no nā ʻike hou aku.
hiki iā mākou ke hāʻawi i nā mea maikaʻi maikaʻi, ka wikiwiki a me ke kōkua mea kūʻai maikaʻi loa.ʻO kā mākou huakaʻi "E hele mai ʻoe i ʻaneʻi me ka paʻakikī a hāʻawi mākou iā ʻoe i kahi minoʻaka e lawe aku" no4140 pahu kila poepoe, Hoʻokō ʻia ka mana maikaʻi koʻikoʻi i kēlā me kēia loulou o ke kaʻina hana holoʻokoʻa. Manaʻolana mākou e hoʻokumu i ka launa aloha a me ka pōmaikaʻi me ʻoe.Ma muli o nā hoʻonā kūlana kiʻekiʻe a me ka lawelawe pre-sales / after-sales maikaʻi loa ko mākou manaʻo, ua hui pū kekahi mau mea kūʻai aku me mākou ma mua o 5 mau makahiki.
Nā hiʻohiʻona
ʻO 4130 4135 4140 4145H nā pahu kila he kila haʻahaʻa kalapona.Aia lākou i ka Chrome-Molly alloy i loaʻa i ka chromium a me ka molybdenum i mea hoʻoikaika ikaika.
ʻO 4130 ka pahu kila a puni ka hana maikaʻi, ka liʻiliʻi o ka hoʻololi ʻana, a me ke kūpaʻa luhi maikaʻi.Aia ia i ka ʻāpana o ke kila hiki ke paʻakikī i waena.Ma hope o ka hoʻomaʻamaʻa ʻana i ka wela, 4140 ka ikaika maikaʻi a me nā waiwai mechanical piha, hiki ke hana maikaʻi, a me nā hua kiʻekiʻe.ʻO ka mahana lawelawe he 427 degere Celsius.
He ikaika kiʻekiʻe ka 4140, hiki ke paʻakikī, paʻakikī, a me ka deformation i ka wā e kinai ana.Loaʻa iā ia ka ikaika kolo kiʻekiʻe a me ka ikaika hoʻomanawanui i nā wela kiʻekiʻe.Hoʻohana ʻia no ka hana ʻana i nā forgings e koi ai i ka ikaika kiʻekiʻe a me nā ʻāpana hoʻopau a me nā ʻāpana ʻoi aku ka nui ma mua o ke kila 4135, e like me nā mīkini nui no ka locomotive traction, booster transmission gears, hope axles, connecting rods a me nā kiʻi puna i hoʻouka nui ʻia.
