Pehea e koho ai i ke kila kila

ʻEkolu mau kumu nui e pili ana i ka ʻino ʻana o ke kila kila ma lalo nei.

1.ʻO ka maʻiʻo o nā mea hoʻohui, ʻo ka ʻōlelo maʻamau, ʻo ka ʻike o ka chromium i ka 10.5% kila ʻaʻole hiki ke maʻalahi.

ʻOi aku ka kiʻekiʻe o ka chromium a me ka nickel, ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion.ʻo kahi laʻana,

ʻO ka maʻiʻo o ka nickel i 304 mea he 8-10%, a hiki i ka chromium ke 18-20%.

ʻAʻole e ʻōpala kēlā ʻano kila kila ma lalo o nā kūlana maʻamau.

2.ʻO ke kaʻina hoʻoheheʻe ʻana o ka mea hana e hoʻopilikia pū i ka pale ʻana o ke kila kila.

ʻO kahi mea kanu kila kila nui me ka ʻenehana hoʻoheheʻe maikaʻi.

Hiki i nā mea hana kiʻekiʻe a me ka ʻenehana kiʻekiʻe ke hōʻoiaʻiʻo i ka mana o nā mea hoʻohuihui,

ka wehe ʻana i nā mea haumia, a me ka mālama ʻana i ka mahana anuanu o ka billet,

no laila paʻa a hilinaʻi ka maikaʻi o ka huahana, maikaʻi ka maikaʻi o loko, a ʻaʻole maʻalahi ka ʻōpala.ʻOiaʻiʻo,

ʻo kekahi mau hale wili kila liʻiliʻi he mau lako a me ka ʻenehana.I ka wā o ka hoʻoheheʻe ʻana,

ʻAʻole hiki ke hoʻoneʻe ʻia nā mea haumia, a ʻo nā huahana i hana ʻia e ʻōpala.

3.ʻO ke kaiapuni waho, kahi maloʻo a me ka ventilated ʻaʻole maʻalahi i ka pala.Eia naʻe,

kiʻekiʻe ka haʻahaʻa o ka ea, ka ua mau ʻana, a i ʻole ke kaiapuni me ka pH kiʻekiʻe i ka lewa e maʻalahi ka pala.

304 kila kila, inā ʻino loa ke kaiapuni a puni, e ʻōpala.

Nui nā mea kūʻai e hele i ka mākeke e kūʻai i ke kila kila a lawe mai i kahi magnet liʻiliʻi me lākou.

Me ka magnetism, ʻaʻohe ʻōpala.ʻOiaʻiʻo, he hoʻomaopopo hewa kēia.

Hoʻoholo ʻia ka ʻili kila kuhili ʻole magnetic e ke ʻano o ka hale.

I loko o ke kaʻina hana paʻa, e hana ke kila hoʻoheheʻe ʻia i "ferrite", "austenite",

"martensite" a me nā kila kila ʻē aʻe me nā hale like ʻole.Iwaena o lakou,

ʻO nā kila kuhiliʻole "ferrite" "Kōno" a me "Martensitic" he mea hoʻokalakupua.

ʻO ke kila kila "Austenitic" maikaʻi nā waiwai mechanical holoʻokoʻa,

kaʻina hana a me ka weldability, akā wale nō ma ke ʻano o ke kūpaʻa corrosion,

ʻoi aku ka ikaika o ke kila kila "ferritic" ma mua o ke kila kila "austenitic".

I kēia manawa, ʻo ka mea i kapa ʻia ʻo 200 series a me 300 series stainless steels me ke kiʻekiʻe

ʻAʻole magnetic ka ʻike manganese a me ka nickel haʻahaʻa i ka mākeke,

akā, ʻokoʻa loa kā lākou hana mai ka 304 me ka nui o ka nickel content.aka,

304 ua kikoo ʻia, hoʻopili ʻia, hoʻoliʻi ʻia, a hoʻolei ʻia.ʻO ka mālama ʻana i ke kaʻina hana he micro-magnetic,

no laila, he kuhihewa a ʻike ʻole ka hoʻoholo ʻana i ka maikaʻi o ke kila kuhili ʻole me ka magnetism.
