ʻO Carbon Steel vs Stainless Steel: He Hoʻohālikelike Hoʻohālikelike
I ke koho ʻana i nā mea hana no nā noi like ʻole, ʻelua o nā metala i manaʻo nui ʻia he kila kalapona a me ke kila kila. Loaʻa iā lāua nā waiwai kūʻokoʻa e kūpono ai no nā kumu like ʻole, akā loaʻa iā lākou nā ʻokoʻa like ʻole e hiki ke hoʻopili i kā lākou hana a me ka uku-pono. Ma kēia ʻatikala, e ʻimi mākou i nā ʻokoʻa koʻikoʻi ma waena o ke kila kalapona a me ke kila kila, e pili ana i ka hiʻohiʻona, ka pale ʻana i ka corrosion, ke kūpaʻa ʻaʻahu, ke kumukūʻai, a me ka ductility.
Ka nana aku
ʻO ke kila kalapona he matte a ʻeleʻele paha, hiki ke ʻokoʻa mai ke kala-hina a hiki i ka hina hina ma muli o ke ʻano o ka alloy a me ka mālama ʻana i ka ʻili. He mea maʻalahi ia i ka oxidation i ka wā e ʻike ʻia ai i ka makū, e alakaʻi ana i ka hoʻokumu ʻana o ka ʻōpala, hiki ke hoʻopilikia i kona hoʻopiʻi aesthetic i ka manawa.
ʻO ke kila kila, ma ka ʻaoʻao ʻē aʻe, ke hoʻokiʻekiʻe nei i kahi ʻālohilohi a me ka hoʻohālikelike ʻana i ka ʻili e kū ʻole i ka ʻili a me ka ʻili. Makemake nui ʻia kēia no nā noi kahi e pono ai ka nānā ʻana i ka maʻemaʻe a me ka poni ʻia, e like me nā lako kīhini, nā hale kūkulu hale, a me nā mea hoʻonaninani.
Pale ʻino
ʻO kekahi o nā hemahema nui o ke kila kalapona ʻo ia kona maʻalahi i ka corrosion. Ke ʻike ʻia i ka makū a me ka ea, hiki i ke kila kalapona ke hoʻoheheʻe koke ʻia, e hana ana i ka pala. ʻAʻole pili wale kēia i ke ʻano o ka mea akā hiki ke hoʻonāwaliwali i kona kūpaʻa i ka wā.
Kaulana ʻia ke kila kila no kona kūpaʻa ʻana i ka corrosion maikaʻi loa, mahalo i ka hele ʻana o ka chromium i loko o kāna hui ʻana. Hoʻokumu ka chromium i kahi pale oxide pale ma luna o ka ʻili o ke kila, kahi e pale ai i ka oxidation a me ka corrosion. ʻO kēia ka mea i kūpono i ke kila kila no ka hoʻohana ʻana i nā kaiapuni kahi i maʻa mau ai ka ʻike ʻana i ka makū, nā kemika, a i ʻole nā mea ʻino ʻē aʻe.
ʻAʻahu Kūʻē
ʻOi aku ka maikaʻi o ka pale ʻana i ka ʻaʻahu ma mua o ke kila kila, ʻoi aku ka nui o nā māka ikaika kiʻekiʻe. ʻO kēia ka mea i koho maikaʻi ʻia no nā noi e koi ai i ka lōʻihi a me ka ikaika, e like me nā mea hana, nā ʻāpana mīkini, a me nā mea hana.
ʻOiai ʻoi aku ka pale ʻana i ka corrosion, ʻoi aku ka haʻahaʻa o ke kila kila ma mua o ke kila kalapona. Eia nō naʻe, hiki ke mālama ʻia kekahi mau māka o ke kila kila, e like me ka martensitic a me ka paʻakikī paʻakikī o ka ua, i ka wela e hoʻomaikaʻi ai i ko lākou paʻakikī a hoʻopaʻa i ke kūpaʻa ʻana, e kūpono ia no nā noi kikoʻī.
Kumukuai
ʻOi aku ke kumukūʻai ma mua o ke kila kila. ʻO kāna kumu kūʻai haʻahaʻa e lilo ia i koho kaulana no nā noi ʻoihana a me nā hana kūkulu kahi e noʻonoʻo ʻia ai nā kaohi kālā.
ʻOi aku ke kumu kūʻai nui o ke kila kila ma muli o ka nui o nā mea hao hao a me nā kaʻina hana paʻakikī. Eia nō naʻe, ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion a me ka lōʻihi o ke ola ʻana hiki ke hōʻoia pinepine i ke kumu kūʻai kiʻekiʻe, ʻoi aku hoʻi i nā noi kahi mea nui o ka mālama ʻana a me ka hoʻololi ʻana.
ʻO ka ductility
ʻOi aku ka ductile ma mua o ke kila kila, no ka mea ʻoi aku ka nui o ka nickel ma ke kila kuhiliʻole, a ʻoi aku ka ductile o kēia mau mea, no laila e ʻoi aku ka ductile. Loaʻa i ka nickel ka liʻiliʻi o ke kila kalapona, hiki ke mālama pono ʻole ʻia, akā maikaʻi ʻole ka ductility.
ʻO ke kila kalapona a me ke kila kuhiliʻole ke ʻano o ka hao a me ke kalapona. ʻO kā lākou ʻokoʻa nui ʻo ia ka mea i hoʻopili ʻia - ʻo ke kila kalapona ka mea i hoʻopaʻa ʻia ma lalo o 10.5%, ʻoiai ʻo ke kila kila he 10.5% a ʻoi aku ka chromium. ʻO kēia ʻokoʻa koʻikoʻi ke kumu i loaʻa ai i ke kila kalapona a me ke kila kuhili ka waiwai kino.
ʻO nā mea kumu o ke kila he hao a me ke kalapona. ʻO ka mea maʻamau, ʻo ke kila me kahi ʻano kalapona kiʻekiʻe he paʻakikī a paʻakikī, ʻoiai ʻo ke kila me kahi haʻahaʻa kalapona he ductile a paʻakikī. ʻOiaʻiʻo, kakaʻikahi ka maʻalahi. Hiki ke hoʻohui ʻia nā mea hoʻohui like e like me chromium, molybdenum, nickel, manganese, a i ʻole silika e hoʻomaikaʻi i ka pale ʻana i ka corrosion a i ʻole e loaʻa i kahi kaulike maikaʻi ma waena o ka ikaika a me ka paʻakikī.
Ke kila kalapona
ʻO ke kila kalapona ka hao a me ka 0.12 - 2.00% kalapona. ʻO kahi wehewehe ākea e pili ana i nā kila kila, hiki ke loaʻa i nā mea i loko o ke kiʻekiʻe he 10.5%. ʻOiai i loko o ka palena o ka liʻiliʻi ma lalo o ʻelua pakeneka o ke kalapona, aia nā ʻokoʻa nui o nā waiwai kino, ʻoi aku ka paʻakikī.
Ke kamaʻilio ka poʻe e pili ana i ke kila kalapona, ʻōlelo pinepine lākou i nā kila kalapona kiʻekiʻe i hoʻohana ʻia no nā pahi a me nā mea hana. ʻO nā kila kalapona kiʻekiʻe he paʻakikī loa, kahi e maikaʻi loa ai lākou i ka pale ʻana i ka ʻaʻahu a mālama i ko lākou ʻano. Hiki iā lākou ke pale i nā ikaika nui ma mua o ka hoʻololi ʻana. ʻO ka mea pōʻino, palupalu nō hoʻi nā metala paʻakikī: ke kau ʻia ma lalo o ke koʻikoʻi tensile, ʻoi aku ka pohā o nā kila kalapona kiʻekiʻe ma mua o ka piko.
ʻOi aku ka maʻamau o nā kila māmā ma mua o nā kila kalapona kiʻekiʻe no ka mea (1) ʻoi aku ke kumu kūʻai o ka hana ʻana, (2) ʻoi aku ka ductile, a (3) maʻalahi ke hana. Hiki i nā kila māmā ke ho'opō'ino ma mua o ka haki 'ana ma lalo o ke ko'iko'i, a ua ma'alahi kēia ductility i ka mīkini a me ka weld. Hoʻohana pinepine ʻia lākou i nā panela kino automotive, bolts, clamps, a me nā pā kila.
Kila kohu ʻole
Loaʻa ka hao, kalapona, a me ka liʻiliʻi o 10.5% chromium maʻiʻo. ʻO Chromium ke kī—e hana me ka oxygen e hana i kahi papa passive e pale i ke kila mai ka ʻino. ʻO kēia pale e hōʻemi ana i ka hiki ʻana o ke kila kila—he mea nui no nā lako waho e hoʻokomo ʻia i nā wahi pulu. ʻOi aku ka kiʻekiʻe o ka chromium maʻiʻo, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion. Ke kūʻai aku i nā mea hana a me nā mea nui ʻē aʻe, e hoʻolohe mau i ka papa kila kila. ʻAʻole hana like nā kila a pau. ʻOi aku ka liʻiliʻi o ke kila kila me ka liʻiliʻi he 10.5% chromium ma mua o ke kila kila me 16% chromium, a e ʻike ʻia ka ʻokoʻa i nā kumukūʻai mālama a me ke ola.
Mahalo iā ʻoe no ka heluhelu ʻana, inā makemake ʻoe e ʻike hou aku i nā mea a mākou e hāʻawi ai hiki iā ʻoe ke hahai i nā loulou ma lalo nei!
