304 paipu kila kila me nā kikoʻī piha
ʻO 06cr19ni10 a me SUS304 nā ʻano mākaʻikaʻi maʻamau, ʻo ia ka 06cr19ni10 e pili ana i ka hana maʻamau ʻāina, ʻo 304 e pili ana i ka hana maʻamau ASTM, a ʻo SUS 304 e pili ana i ka hana maʻamau Iapana.
ʻO 304 kahi kila kuhili honua, i hoʻohana nui ʻia no ka hana ʻana i nā mea hana a me nā ʻāpana e koi ana i ka hana holoʻokoʻa maikaʻi (ke kūpaʻa corrosion a me ka formability). No ka mālama ʻana i ke kūpaʻa ʻino o ke kila kila, pono ke kila ma mua o 18% chromium a ʻoi aku ma mua o 8% nickel. ʻO ka 304 stainless steel kahi hōʻailona o ke kila kila i hana ʻia e like me nā kūlana ASTM ʻAmelika.

No ke kila kila 304, he mea koʻikoʻi ka mea Ni i loko o kāna ʻano, kahi e hoʻoholo pololei ai i ke kūpaʻa corrosion a me ka waiwai o 304 stainless steel.
ʻO nā mea nui loa ma 304 ʻo Ni a me Cr, akā ʻaʻole i kaupalena ʻia i kēia mau mea ʻelua. Hōʻike ʻia nā koi kikoʻī i ka maʻamau huahana. Wahi a ka hoʻoholo maʻamau i ka ʻoihana, hiki ke noʻonoʻo ʻia ʻo 304 stainless steel i ka wā i ʻoi aku ka nui o ka Ni ma mua o 8% a ʻoi aku ka nui o ka Cr ma mua o 18%. ʻO ia ke kumu i kapa ʻia ai kēia ʻano kila kila 18 / 8 i loko o ka ʻoihana. ʻO ka ʻoiaʻiʻo, ʻo nā kūlana huahana pili i loaʻa nā ʻōlelo akaka loa ma 304, a he mau ʻokoʻa kēia mau huahana huahana no nā ʻano like ʻole o ke kila kila. Eia kekahi mau huahana maʻamau a me nā hoʻāʻo.
No ka hoʻoholo inā he 304 stainless steel kahi mea, pono ia e hoʻokō i nā koi o kēlā me kēia mea i ka maʻamau huahana. I ka wā e hoʻokō ʻole ai kekahi i nā koi, ʻaʻole hiki ke kapa ʻia ʻo 304 stainless steel.
