Ua hoʻokaʻawale ʻia ke kila i ʻehā mau pūʻulu: Nā kila kalapona, Nā kila hao, Nā kila kila kila
ʻAno 1-Nā kila kalapona
Ma waho aʻe o ke kalapona a me ka hao, aia nā kila kalapona i nā ʻāpana liʻiliʻi wale nō o nā ʻāpana ʻē aʻe. ʻO nā kila kalapona ka mea maʻamau o nā papa kila ʻehā, e helu ana i 90% o ka hana kila holoʻokoʻa! Ua hoʻokaʻawale ʻia ke kila kalapona i ʻekolu mau hui liʻiliʻi e pili ana i ka nui o ke kalapona i loko o ka metala:
Nā kila kalapona haʻahaʻa/kila akahai (a hiki i ka 0.3% kalapona)
Nā kila kalapona waena (0.3–0.6% kalapona)
Nā kila kalapona kiʻekiʻe (ʻoi aku ma mua o 0.6% kalapona)
Hoʻopuka pinepine nā ʻoihana i kēia mau kila i nā nui he nui no ka mea he ʻano kūʻai ʻole a paʻa hoʻi e hoʻohana ʻia i ke kūkulu ʻana me ka nui.
ʻAno 2-Nā kila hao
Hana ʻia nā kila hao ma ka hoʻohui ʻana i ke kila me nā mea hoʻohui hou e like me ka nickel, ke keleawe, ka chromium a/a i ʻole ka alumini. Hoʻomaikaʻi ka hoʻohui ʻana i kēia mau mea i ka ikaika, ka ductility, ke kūpaʻa i ka pala a me ka machinability o ke kila.
ʻAno 3-Nā kila kila ʻole
Hoʻohui ʻia nā papa kila kila me 10-20% chromium a me ka nickel, silicon, manganese, a me ke kalapona. Ma muli o ko lākou hiki ke ola i nā wā ʻino, he kiʻekiʻe loa ke kūpaʻa o kēia mau kila i ka pala a palekana hoʻi e hoʻohana i ke kūkulu ʻana i waho. Hoʻohana pinepine ʻia nā papa kila kila i nā mea uila.
Eia kekahi laʻana, ua ʻimi nui ʻia ke kila kila 304 no kona hiki ke kū i ke kaiapuni me ka mālama ʻana i nā mea uila.
ʻOiai he wahi ko nā ʻano kila kila like ʻole, me ke kila kila 304, i loko o nā hale, ʻoi aku ka ʻimi pinepine ʻia o ke kila kila no kona mau waiwai maʻemaʻe. Loaʻa nui kēia mau kila i nā mea lapaʻau, nā paipu, nā ipu kaomi, nā mea ʻoki a me nā mīkini hana meaʻai.
ʻAno 4-Nā kila mea hana
ʻO nā kila mea hana, e like me ka inoa e hōʻike nei, ʻoi aku ka maikaʻi i ka ʻoki ʻana a me ka wili ʻana i nā lako. ʻO ke alo o ka tungsten, molybdenum, cobalt a me vanadium e kōkua i ka hoʻomaikaʻi ʻana i ke kūpaʻa wela a me ke kūpaʻa maʻamau. A no ka mea e paʻa ana ko lākou ʻano ʻoiai ma lalo o ka hoʻohana nui ʻana, ʻo lākou ka mea makemake nui ʻia no ka hapa nui o nā mea hana lima.
Nā hoʻokaʻawale kila
Ma waho aʻe o nā hui ʻehā, hiki ke hoʻokaʻawale ʻia ke kila ma muli o nā ʻano like ʻole e like me:
ʻAno: kalapona kalapona, metala, kila kila, a pēlā aku.
ʻAno hoʻopau: ʻōwili wela, ʻōwili anu, hoʻopau anu, a pēlā aku.
ʻAno hana: umu uila, hoʻolei mau, a pēlā aku.
ʻAno hana liʻiliʻi: ferritic, pearlitic, martensitic, etc.
Ikaika kino: e like me nā kūlana ASTM
Kaʻina hana de-oxidation: pepehi ʻia a hapa paha i pepehi ʻia
Ka mālama wela: annealed, tempered, etc.
Ka inoa inoa maikaʻi: maikaʻi kalepa, maikaʻi o ke kīʻaha kaomi, maikaʻi o ke kaha kiʻi, a pēlā aku.
He aha ke kila maikaʻi loa?
ʻAʻohe papa "maikaʻi loa" o ke kila, ʻoiai ʻo ke papa kila kūpono loa no kahi noi e pili ana i nā kumu he nui, e like me ka hoʻohana i manaʻo ʻia, nā koi mechanical a me ke kino, a me nā palena kālā.
ʻO nā papa kila i hoʻohana mau ʻia a manaʻo ʻia ʻo ia ka moʻo kiʻekiʻe loa mai kēlā me kēia ʻano:
Nā kila kalapona: A36, A529, A572, 1020, 1045, a me 4130
Nā kila hao: 4140, 4150, 4340, 9310, a me 52100
Nā kila kila ʻole: 304, 316, 410, a me 420
Nā kila mea hana: D2, H13, a me M2
ʻO JINDALAI ka hui kila alakaʻi e hiki ke hoʻolako i nā ʻano kila āpau i loko o ke coil, sheet, pipe, tube, rod, bar, flanges, elbows, tees, a pēlā aku. E hāʻawi iā Jindalai i kahi manaʻo hilinaʻi, a e māʻona ʻoe i ka huahana.
