ʻO 17-4 ke kila kila, i ʻōlelo pinepine ʻia e kāna mau kikoʻī AMS 5643, AISI 630, a me UNS S17400, ʻo ia kekahi o nā kila paʻakikī paʻakikī. ʻIke ʻia no kona ikaika ʻokoʻa, kūpaʻa kiʻekiʻe i ka corrosion, a me ka maʻalahi o ka mīkini, he mea maʻalahi ia no nā ʻoihana like ʻole. Ma kēia ʻatikala, e ʻimi mākou i nā hiʻohiʻona, nā noi, a me nā pōmaikaʻi o 17-4 stainless steel, me ke kumu i koho ʻia ai no nā ʻoihana he nui.
He aha ka 17-4 Stainless Steel?
17-4 kila kilaʻO ke kila kila kila martensitic i loaʻa ka 15-17% chromium a me 3-5% nickel. Hana ʻia ke koena i ka hao, me nā mea ʻē aʻe e like me ke keleawe, molybdenum, a me ka niobium i hoʻohui ʻia e hoʻonui i kona mau waiwai. ʻIke ʻia ʻo ia no kona ikaika kiʻekiʻe, paʻakikī, a me ke kūʻē ʻana i ka corrosion i nā ʻano like ʻole.
ʻO ka inoa "17-4" e pili ana i kona haku mele, me 17% chromium a me 4% nickel, e hāʻawi ana i ke kila i kona mau waiwai ʻokoʻa.
Nā mea nui o 17-4 Kuleana kila
1. Ka ikaika kiʻekiʻe a me ka paʻakikī
ʻO kekahi o nā hiʻohiʻona o 17-4 stainless steel kona ikaika. Ma o ke kaʻina hana hoʻomaʻamaʻa wela i kapa ʻia ʻo ka paʻakikī o ka ua, hiki i kēia huila i nā ikaika tensile kupaianaha, i kūpono no nā noi hana kiʻekiʻe. Ke paʻakikī, hiki i ka 17-4 ke kila kila ke loaʻa nā ikaika hua a hiki i 130 KSI (896 MPa) a me nā ikaika tensile o 160 KSI (1100 MPa).
2. Kū'ē Kū'ē maikaʻi
Ma muli o kona kiʻekiʻe o ka chromium,17-4 kila kilahe kūpaʻa maikaʻi loa i ka ʻinoʻino, ʻoi aku ka maikaʻi ma nā wahi ʻino haʻahaʻa. Hana maikaʻi ʻo ia i nā kūlana acidic a me ka alkaline, kūpono ia no kahi ākea o nā noi i nā ʻoihana e like me ka aerospace, kemika, a me ka petrochemical.
3. Versatility i ka wela wela
ʻAʻole like me nā mea kila kila ʻē aʻe, hiki i ka 17-4 ke kila kila ke hoʻomaʻamaʻa ʻia e hoʻokō i kahi ʻano o nā waiwai mechanical. Ma ka hoʻololi ʻana i ka mahana i ka wā mālama wela, hiki i nā mea hana ke hana i ka paʻakikī a me ka ikaika o ka mea. ʻO kēia ka mea hiki ke hoʻololi ʻia no nā noi like ʻole, inā i loko o nā ʻāpana hana a i ʻole nā kaiapuni koʻikoʻi.
4. Weldability kiʻekiʻe
ʻOiai ʻo nā kila kuhili ʻole martensitic ka mea maʻamau i nā luʻi i ka wili, 17-4 ʻoi aku ka maikaʻi o ka weldability i hoʻohālikelike ʻia me nā kila ʻē aʻe o kāna papa. Hiki ke hoʻopili ʻia me ka hoʻohana ʻana i nā ʻano kuʻuna, e like me ke kinoea tungsten arc welding (GTAW), me ka ʻole o ka hoʻohaumia ʻana i kona ikaika a i ʻole ke kūpaʻa corrosion. Eia naʻe, ʻōlelo ʻia ka mālama ʻana i ka wela post-weld kūpono e mālama i kāna mau waiwai i makemake ʻia.
5. Maʻalahi o ka Mīkini
ʻO kekahi pono o ka 17-4 stainless steel ʻo ia ka maʻalahi o ka mīkini. ʻOiai paʻakikī, maʻalahi ka hana ʻana me ka hoʻohana ʻana i nā ʻenehana mīkini maʻamau, e ʻae ai i nā ʻano paʻakikī a me nā hoʻolālā e hana maikaʻi ʻia. Hoʻohana nui kēia hiʻohiʻona i nā mea hana e koi ana i ka pololei kiʻekiʻe i kā lākou ʻāpana.
Nā mea hoʻohana o 17-4 Stainless Steel
ʻO nā mea kūikawā o ka 17-4 stainless steel e kūpono i nāʻano noi koi. ʻO kekahi o nā ʻoihana maʻamau e hoʻohana ana i ka 17-4 stainless steel penei:
-
Aerospace a me ka mokulele
ʻO ka 17-4 stainless steel kahi koho kaulana i ka ʻoihana aerospace ma muli o kona hui pū ʻana o ka ikaika kiʻekiʻe, nā waiwai māmā, a me ke kūʻē i ka corrosion. Hoʻohana pinepine ʻia ia i ka hana ʻana i nā lau turbine, nā ʻāpana compressor, nā shafts, a me nā mea hana o ka mokulele. -
ʻOihana Kimia a me Petrochemical
ʻO ke kūpaʻa ʻana i ka corrosion e hana ai i ka 17-4 stainless steel i koho maikaʻi loa no nā mea hana i ʻike ʻia i nā kemika koʻikoʻi a me nā kaiapuni, e pili ana i nā valves, pumps, a me nā moku kaomi. Hiki iā ia ke pale i ka ʻike lōʻihi i nā mea waikawa a me ka alkaline, e mālama ana i kona kūpaʻa a me kāna hana. -
Na Lapaau Lapaau
Ma ke kahua lapaʻau, hoʻohana ʻia ka 17-4 stainless steel i ka hana ʻana i nā mea hana ʻokiʻoki, implants, a me nā mea hana. ʻO kona biocompatibility, i hui pū ʻia me kona ikaika kiʻekiʻe a me ke kūpaʻa corrosion, lilo ia i mea kūpono no nā noi lapaʻau e pono ai ka lōʻihi a me ka maʻemaʻe. -
Nā noi moana a me waho
ʻO ke kūpaʻa o ka alloy i ka ʻino wai paʻakai kūpono ia no ka hoʻohana ʻana i nā kaiapuni kai, kahi e pono ai nā mea ikaika kiʻekiʻe no nā mea e like me nā propeller shafts, pumps, a me nā mea paʻa. -
Lako Hana Hana
Hoʻohana ʻia ʻo 17-4 stainless steel i nā ʻano mīkini ʻenehana like ʻole, e komo pū ana me nā gears, shafts, a me nā valves, kahi i koʻikoʻi ai ka ikaika a me ka pale ʻana i ka corrosion. ʻO kāna versatility a me kāna hana e lilo ia i mea koho maikaʻi loa no kēia mau wahi koʻikoʻi kiʻekiʻe.
Nā Pōmaikaʻi o ke koho ʻana i ka 17-4 Stainless Steel
1. Hoʻomaikaʻi i ka lōʻihi a me ka hana
Mahalo i kona hui pū ʻana o ka ikaika, ka paʻakikī, a me ka pale ʻana i ka corrosion,17-4 kila kilahoʻonui i ke ola o nā ʻāpana i nā noi koi. ʻO nā ʻāpana i hana ʻia mai ka 17-4 stainless steel ʻoi aku ka liʻiliʻi o ka ʻeha ʻana i ka ʻaʻahu, corrosion, a luhi paha, e hōʻoia ana i ka lōʻihi o ka lawelawe ʻana a me ka hoʻemi ʻana i nā kumukūʻai mālama.
2. ʻAi Kūʻai Kūʻai
ʻOiai hiki ke kūʻai nui ʻia nā ʻāpana kila kila, hāʻawi ʻo 17-4 stainless steel i kahi hopena maikaʻi loa ma ka hāʻawi ʻana i ka hana kiʻekiʻe ma kahi kumu kūʻai hoʻokūkū. I ka noʻonoʻo ʻana i ke ola holoʻokoʻa a me ka hoʻemi ʻana i ka pono o ka mālama ʻana, hōʻike ʻia ia he koho waiwai waiwai no nā ʻoihana he nui.
3. Hana maʻalahi
Me kona hiki ke hoʻomaʻamaʻa wela no nā waiwai kikoʻī, hāʻawi ʻo 17-4 stainless steel i kahi pae o ka hana maʻamau ʻaʻole hiki ke hoʻohālikelike ʻia nā ʻāpana ʻē aʻe. ʻO kēia maʻalahi e hiki ai i nā mea hana ke hoʻopili i nā mea e hoʻokō pono i ka ikaika a me nā koi paʻa no nā papahana kikoʻī.
Ka hopena
ʻO 17-4 ke kila kila (AMS 5643, AISI 630, UNS S17400) he mea maʻalahi a hilinaʻi hoʻi e hāʻawi ana i kahi kaulike kūpono o ka ikaika kiʻekiʻe, ke kūpaʻa corrosion, a me ka maʻalahi o ka mīkini. Inā ʻoe e hana ana i ka aerospace, ka hana kemika, a i ʻole kekahi ʻoihana hana kiʻekiʻe, ua hoʻolālā ʻia kēia alloy e hoʻokō i nā koi koi. Ma kaHAAWINA SAKY, Haʻaheo mākou i ka hoʻolako ʻana i kēia mea waiwai kiʻekiʻe, e hōʻoiaʻiʻo ana e pōmaikaʻi kāu mau papahana mai ka maikaʻi o ka ʻoihana.
Me kona mau hiʻohiʻona kiʻekiʻe a me ka laulā o nā noi,17-4 kila kilake hoʻomau nei i kahi koho no nā ʻenekinia a me nā mea hana e ʻimi nei i kahi hopena hilinaʻi a paʻa no kā lākou mau noi koʻikoʻi.
