Nā Lapaʻau Lapaʻau o ke kila kila 304 (UNS S30400)

Hoʻohana mākou i nā kuki e hoʻonui i kou ʻike. Ma ka hoʻomau ʻana i ka nānā ʻana i kēia pūnaewele e ʻae ʻoe i kā mākou hoʻohana ʻana i nā kuki. ʻIke hou aku.
Ma ko lākou ʻano maoli, pono nā mea i hoʻolālā ʻia no ka hoʻohana lāʻau lapaʻau e kūpono i ka hoʻolālā paʻa loa a me nā kūlana hana.
ʻO ka hoʻolālā a me ke kaʻina hana o nā mea lapaʻau e hōʻike ana i kekahi o nā mea paʻakikī loa i ka ʻepekema a me nā pilikia ʻenekinia no ka ʻoihana lapaʻau.
ʻO ke kila kila kekahi o nā mea maʻamau i hoʻohana ʻia no ka hana ʻana i nā mea lapaʻau, ʻoi aku ka nui o ke kila kila 304.
Ua ʻike ʻia ke kila kila 304 ma ka honua holoʻokoʻa ʻo ia kekahi o nā mea kūpono loa no ka hana ʻana i nā mea lapaʻau no nā noi like ʻole.
ʻO ke kūpaʻa kiʻekiʻe o ka corrosion a me ka haʻahaʻa carbon content nā kumu nui e kūpono ai ka 304 stainless steel no nā noi olakino ma luna o nā papa ʻē aʻe o ke kila kila.
ʻAʻole wale ka ikaika o ke kila kila 304, he mea kūpono loa ia a hiki ke huki hohonu me ka ʻole o ka annealing, e hoʻolilo iā 304 i mea kūpono no ka hana ʻana i nā kīʻaha, nā poho, nā pā a me nā ʻano mea lapaʻau like ʻole a me nā hollowware.
Nui nō hoʻi nā ʻano like ʻole o ke kila kila 304 me nā waiwai waiwai i hoʻomaikaʻi ʻia no nā noi kikoʻī, e like me 304L, kahi ʻano kalapona haʻahaʻa, no nā kūlana anana koʻikoʻi e koi ai i nā welds ikaika kiʻekiʻe. Hiki i nā mea lapaʻau ke loaʻa i ka 304L kahi e koi ʻia ai ke kuʻi ʻana e pale i nā ʻano o nā haʻalulu, ke kaumaha lōʻihi a / a i ʻole ke kānana, a pēlā aku. ʻOi aku ka pale ʻana o ka 304L i ka corrosion intergranular ma mua o nā māka hoʻohālikelike o ke kila kila.
ʻO ka hui pū ʻana o ka ikaika haʻahaʻa haʻahaʻa a me ka hiki ke elongation kiʻekiʻe, ʻo ia ka 304 stainless steel he kūpono no ka hana ʻana i nā ʻano paʻakikī me ka ʻole o ka annealing.
Inā makemake ka lāʻau lapaʻau i ke kila kila ʻoi aku ka paʻakikī a ʻoi aku ka ikaika, hiki i ka 304 ke hana paʻakikī e ka hana anu. Ma ke kūlana annealed, 304 a me 304L he ductile loa a hiki ke hana maʻalahi, kūlou, huki hohonu a hana ʻia.
Hoʻohana nui ʻia ʻo 304 stainless steel i nā ʻano ʻenehana a me nā noi hale.
No nā kila kila kila, hoʻohana nui ʻia nā māka kūikawā o ke kila kila - 316 a me 316L. Ma ka hoʻohui ʻana i nā mea chromium, nickel a me molybdenum, hāʻawi ke kila kila i nā mea ʻepekema a me nā kauka lapaʻau i kekahi mau ʻano kūʻokoʻa a hilinaʻi.
E akahele - I nā hihia koʻikoʻi, ʻike ʻia ka ʻōnaehana pale kanaka e pane ʻino (ka ʻili a me ke kino holoʻokoʻa) i ka ʻike nickel i kekahi mau mea kila kila.
No ka laʻana, ua hōʻuluʻulu ka papa inoa ma lalo nei i kekahi mau noi lāʻau lapaʻau no ke kila kuhili.
ʻO nā manaʻo i hōʻike ʻia ma ʻaneʻi, ʻo ia nā manaʻo o ka mea kākau a ʻaʻole pono e hōʻike i nā manaʻo a me nā manaʻo o AZoM.com.
Ma Advanced Materials i Iune 2022, ua kamaʻilio ʻo AZoM me Ben Melrose o International Syalons e pili ana i ka mākeke waiwai holomua, ʻOihana 4.0, a me ka pana ʻana i ka net zero.
Ma Advanced Materials, ua kamaʻilio ʻo AZoM me General Graphene's Vig Sherrill e pili ana i ka wā e hiki mai ana o ka graphene a pehea e hoʻemi ai kā lākou ʻenehana hana hou i nā kumukūʻai e wehe i kahi honua hou o nā noi i ka wā e hiki mai ana.
I loko o kēia nīnauele, kamaʻilio ʻo AZoM me Levicron Pelekikena Dr. Ralf Dupont e pili ana i ka hiki o ka spindle kaʻa hou (U)ASD-H25 no ka ʻoihana semiconductor.
E ʻike i ka OTT Parsivel², he mika hoʻoneʻe laser hiki ke hoʻohana ʻia e ana i nā ʻano ua.
Hāʻawi ʻo Environics i nā ʻōnaehana permeation paʻa ponoʻī no nā paipu permeation hoʻohana hoʻokahi a nui paha.
ʻO ka MiniFlash FPA Vision Autosampler mai Grabner Instruments he autosampler 12-kūlana.
Hāʻawi kēia ʻatikala i kahi loiloi hope o ke ola o nā pā lithium-ion, e kālele ana i ka hoʻonui hou ʻana o nā pākahi lithium-ion i hoʻohana ʻia no nā ala hoʻomau a puni i ka hoʻohana ʻana a me ka hoʻohana hou ʻana.
ʻO ka corrosion ka hoʻohaʻahaʻa ʻana o kahi huila ma muli o ka ʻike ʻana i ke kaiapuni.
Ma muli o ka piʻi ʻana o ka noi no ka ikehu, hoʻonui ʻia ka noi no ka wahie nuklea, e alakaʻi hou ana i ka piʻi nui o ka noi no ka ʻenehana post-irradiation inspection (PIE).
