SAE4130 Steel Round Bar AISI 4130 Alloy Steel Bar
Ke ʻimi nei mākou i ka ʻōlelo hoʻokele o ka "Quality is exceptional, Assistance is supreme, Reputation is first", a e hana maoli a kaʻana like i ka kūleʻa me nā mea kūʻai aku a pau no SAE4130 Steel Round Bar AISI 4130 Alloy Steel Bar, Ke ʻimi mau nei mākou e hoʻokumu i ka pilina me nā mea hoʻolako hou e hoʻolako i ka holomua a me ka naʻauao i kā mākou mea kūʻai waiwai.
Ke ʻimi nei mākou i ka manaʻo hoʻokele o ka "Quality is exceptional, Assistance is supreme, Reputation is first", a e hana maoli a kaʻana like i ka kūleʻa me nā mea kūʻai aku āpau no4130 Bara hao, Manaʻolana mākou hiki iā mākou ke hoʻokumu i ka hui lōʻihi me nā mea kūʻai a pau.A lana ka manaʻo e hiki iā mākou ke hoʻomaikaʻi i ka hoʻokūkū a hoʻokō i ke kūlana win-win me nā mea kūʻai aku.Hoʻokipa maikaʻi mākou i nā mea kūʻai mai ka honua holoʻokoʻa e hoʻokaʻaʻike mai iā mākou no kekahi mea āu e makemake ai!
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.
