ʻO ka 304 stainless steel he ʻano o ka austenitic stainless steel i hoʻohana nui ʻia i nā noi ʻoihana like ʻole ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion, ikaika, a me ka ductility. Hoʻokumu ʻia ia i nā mea kikoʻī e hāʻawi iā ia i kona mau ʻano a me nā ʻano.
Mea nui
ʻO nā mea nui o ka 304 stainless steel sheet he hao, carbon, chromium, a me nickel. ʻO ka hao ka mea kumu, e hāʻawi ana i ke kila me kona ikaika a me ka ductility. Hoʻohui ʻia ke kalapona i mea e hoʻonui ai i ka paʻakikī a me ka lōʻihi o ke kila, akā pono ia i loko o nā haʻahaʻa haʻahaʻa loa e pale ai i ka hōʻemi ʻana i ke kūpaʻa ʻana.
ʻElemu Chromium
ʻO Chromium ka mea koʻikoʻi loa i ka 304 stainless steel, ʻoiai ʻo ia ke kuleana no kona pale ʻana i ka corrosion. Hoʻokumu ʻo Chromium i kahi ʻāpana oxide pale ma ka ʻili o ke kila ke ʻike ʻia i ka oxygen, e pale ana i ka ʻōpala a me ka ʻino. Ma 304 stainless steel, ʻo ka maʻiʻo chromium ma kahi o 18-20% ma ke kaumaha.
ʻElemu nikela
ʻO Nickel kekahi mea koʻikoʻi o 304 stainless steel, aia i loko o nā manaʻo o 8-10% ma ke kaumaha. Hoʻomaikaʻi ʻo Nickel i ka ductility a me ka paʻakikī o ke kila, ʻoi aku ka paʻa ʻana i ka haki ʻana a me ka haki ʻana. Hoʻonui ia i ka pale ʻana i ka corrosion, ʻoi aku ka nui o nā kaiapuni i loko o ka chloride.
Kakaʻikahi nā mea ʻē aʻe
Ma waho aʻe o kēia mau mea mua, hiki i ka 304 ke kila kila kila ke loaʻa i nā mea liʻiliʻi e like me ka manganese, silicon, sulfur, phosphorus, a me ka nitrogen. Hoʻohui ʻia kēia mau mea e hoʻololi i nā waiwai o ke kila a hoʻomaikaʻi i kāna hana ma nā noi kikoʻī.
I ka hōʻuluʻulu ʻana, ʻo ka haku ʻana o ka 304 stainless steel sheet ma luna o ka hao, me ka chromium a me ka nickel e like me nā mea hoʻohui kī. ʻO kēia mau mea, me nā mea liʻiliʻi o nā mea ʻē aʻe, hāʻawi i ka 304 stainless steel i kona kūpaʻa maikaʻi ʻana i ka corrosion, ductility, a me ka hana wela kiʻekiʻe. Hana ʻia kēia ʻano hana ʻokoʻa i ka 304 stainless steel sheet i mea nui loa i kūpono no ka nui o nā noi.
