ʻO ke kila 304 he kila kila maʻamau, ʻike ʻia ʻo 18/8 stainless steel i ka ʻoihana.ʻOi aku ka maikaʻi o kona pale ʻana i ka corrosion ma mua o 430 stainless steel, akā ʻoi aku ka liʻiliʻi o ke kumu kūʻai ma mua o 316 stainless steel, no laila ua hoʻohana nui ʻia i ke ola, e like me: kekahi mau mea kiʻekiʻe kiʻekiʻe kuhiliʻole kila, waho kuhiliʻole kila hao, etc. ʻOiai 304 kila mea. loa ma Kina, ka inoa "304 kila" mai ka United States.Manaʻo ka poʻe he 304 kila he inoa hoʻohālike ma Iapana, akā ʻo ka ʻōlelo koʻikoʻi, ʻo ka inoa kūhelu o 304 steel ma Iapana ʻo "SUS304".ʻO ke kila 304 ke ʻano o ke kila kuhili honua, i hoʻohana nui ʻia i ka hana ʻana i nā mea hana a me nā ʻāpana e koi ana i ka hana piha maikaʻi (ka pale ʻana i ka corrosion a me ka formability).No ka mālama ʻana i ke kūpaʻa corrosion i loko o ke kila kila, pono e loaʻa ke kila ma mua o 16% chromium a ʻoi aku ma mua o 8% nickel content.ʻO ka 304 stainless steel kahi hōʻailona o ke kila kila i hana ʻia e like me ka maʻamau ʻAmelika ASTM.Ua like ka 304 me 0Cr18Ni9 kila kila ma ko mākou ʻāina.

ʻO ka helu kemika o 304 kila he 06Cr19Ni10 (ka papa kahiko -0Cr18Ni9) i loaʻa ka 19% chromium a me 8-10% nickel.

No ke kila 304 he mea koʻikoʻi nui ia, e hoʻoholo pololei i kona kūpaʻa corrosion, akā hoʻoholo pū i kona waiwai.ʻO nā mea koʻikoʻi ma 304 kila ʻo Ni a me Cr, akā ʻaʻole i kaupalena ʻia i kēia mau mea ʻelua.Hōʻike ʻia nā koi kikoʻī e nā kūlana huahana.Manaʻo ka manaʻo maʻamau o ka ʻoihana inā ʻoi aku ka nui o ka Ni ma mua o 8%, ʻoi aku ka nui o Cr ma mua o 18%, hiki ke manaʻo ʻia he 304 kila.ʻO kēia ke kumu i kapa ai ka ʻoihana i kēia ʻano o ke kila kila 18/8 kila kila.ʻO kaʻoiaʻiʻo, ʻo nā kūlana huahana kūpono no ke kila 304 he mau mea akaka loa, a ʻo kēia mau huahana huahana no nā ʻano like ʻole o ke kila kila a aia kekahi mau ʻokoʻa.
