Hoʻokaʻawale ʻia ke kila a hoʻokaʻawale ʻia i ʻehā pūʻulu: ʻO nā kila carbon, Nā kila kila, Na kila kila
ʻAno 1-Na kila kalapona
Ma waho aʻe o ke kalapona a me ka hao, loaʻa i nā kila kalapona ka nui o nā mea ʻē aʻe.ʻO nā kila kalapona ka mea maʻamau o nā māka kila ʻehā, ʻo 90% ka nui o ka hana kila!Hoʻokaʻawale ʻia ke kila kalapona i ʻekolu mau pūʻulu ma muli o ka nui o ke kalapona i loko o ka metala:
l Nā kila kalapona haʻahaʻa / nā kila māmā (hiki i ka 0.3% carbon)
l Nā kila kalapona liʻiliʻi (0.3–0.6% kalapona)
l Nā kila kalapona kiʻekiʻe (ʻoi aku ma mua o 0.6% kalapona)
Hoʻopuka pinepine nā ʻoihana i kēia mau kila i ka nui no ka mea ʻoi aku ka liʻiliʻi a me ka ikaika e hoʻohana ʻia i ka hana nui.
ʻAno 2-Nā kila kila
Hana ʻia nā kila kila ma ka hui ʻana i ke kila me nā mea hoʻohui hou e like me nickel, copper, chromium a me / a i ʻole alumini.ʻO ka hui pū ʻana i kēia mau mea e hoʻomaikaʻi i ka ikaika, ductility, corrosion resistance a me ka machinability o ke kila.
ʻAno 3-Na kila kila
Hoʻohui ʻia nā māka kila kila me ka 10-20% chromium a me ka nickel, silicon, manganese, a me ke kalapona.Ma muli o ka nui o ko lākou hiki ke ola i ka wā ʻino, ʻoi aku ka kiʻekiʻe o kēia mau kila i ka corrosion resistance a palekana ke hoʻohana ʻia i ke kūkulu ʻana i waho.Hoʻohana mau ʻia nā māka kila kila i nā mea uila.
No ka laʻana, ʻimi nui ʻia ʻo 304 stainless steel no kona hiki ke kū i ke kaiapuni me ka mālama pono ʻana i nā mea uila.
ʻOiai he wahi i loko o nā hale nā papa kila kila ʻē aʻe, me ka 304 stainless steel, ʻimi pinepine ʻia ke kila kila no kāna mau mea maʻemaʻe.Loaʻa kēia mau kila i nā mea lapaʻau, nā paipu, nā kīʻaha kaomi, nā mea ʻoki a me nā mīkini hana meaʻai.
ʻAno 4-Nā kila kila
ʻO nā kila mea hana, e like me ka inoa e hōʻike ai, ʻoi aku ka maikaʻi i ka ʻoki a me ka ʻeli ʻana.ʻO ka loaʻa ʻana o ka tungsten, molybdenum, cobalt a me ka vanadium e kōkua i ka hoʻomaikaʻi ʻana i ka pale wela a me ka lōʻihi maʻamau.A no ka paʻa ʻana o ko lākou ʻano ma lalo o ka hoʻohana koʻikoʻi, ʻo ia ka mea i makemake ʻia no ka hapa nui o nā mea hana lima.
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:
Hoʻohui: kalapona kalapona, alloy, stainless, etc.
ʻO ke ʻano hoʻopau: ʻōwili wela, ʻōwili anu, hoʻopau anu, etc.
Keʻano hana: ka umu uila, hoʻolei mau, etc.
Microstructure: ferritic, pearlitic, martensitic, etc.
Ka ikaika kino: no nā kūlana ASTM
Kaʻina de-oxidation: pepehi a semi-pepehi ʻia
Hoʻomaʻamaʻa wela: annealed, tempered, etc.
Nomenclature maikaʻi: maikaʻi kālepa, maikaʻi o ka moku kaomi, maikaʻi kiʻi, etc.
He aha ka papa kila maikaʻi loa?
ʻAʻohe kūlana kila "maikaʻi" o ke ao holoʻokoʻa, no ka mea, ʻo ka pae kila maikaʻi 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 māka kila i hoʻohana mau ʻia a manaʻo ʻia ʻo ka moʻo kiʻekiʻe mai kēlā me kēia ʻano:
Nā kila kalapona: A36, A529, A572, 1020, 1045, a me 4130
Nā kila kila: 4140, 4150, 4340, 9310, a me 52100
Nā kila kila: 304, 316, 410, a me 420
Nā kila mea hana: D2, H13, a me M2
ʻO JINDALAI ka hui kila alakaʻi e hiki ai ke hoʻolako i nā papa kila a pau i loko o ka coil, sheet, pipe, tube, rod, bar, flanges, elbows, tees, etc. Hāʻawi iā Jindalai i ka hilinaʻi, a e māʻona ʻoe i ka huahana.
