Nā waiwai o 304 Kuhili ʻole

I loko o kēia ao waihoʻoluʻu, aia kahi metala e hoʻohui i ke kūpaʻa a me ka nani, hiki ke kū i ka ʻāʻī ʻana o nā kaiapuni koʻikoʻi i ka wā e pāʻani ana i kahi hana koʻikoʻi i ke ola hou - ʻo ia ka protagonist o kā mākou moʻolelo i kēia lā - 304'ōpana kila. No laila, he aha nā mea pohihihi waiwai o 304 kila kuhiliʻole? E hoʻomaka pū kākou i kēia huakaʻi ʻimi!

Nā waiwai o 304 Stainless Steel - 304 Stainless Steel's Corrosion Resistance

ʻO kekahi o nā mea nui loa waiwai o 304 kila kuhiliʻole ʻo ia ka maikaʻi o kona pale ʻana i ka corrosion. He mea kūpono loa kēia waiwai no ka hoʻohana ʻana i nā kaiapuni koʻikoʻi a me nā ʻoihana e like me ka hana kemika, ka hoʻoili ʻana i nā meaʻai, a me nā noi kai.

Hiki ke hoʻohālikelike ʻia ke kūpaʻa corrosion o 304 stainless steel i ke alo o ka chromium (18-20%) a me ka nickel (8-10.5%). Hoʻopili kēia mau mea me ka oxygen i ka lewa a i ʻole ka wai, e hana ana i kahi ʻāpana lahilahi o ka oxide ma luna o ka ʻili e lilo i mea pale e pale aku ai i ka oxidation a i ʻole ka ʻōpala.

Eia kekahi, ʻo kēia ʻano ʻano kila kila he wahi liʻiliʻi o ka molybdenum (2-3%) e hoʻonui ai i kona kūʻē ʻana i ka pitting a me ka crevice corrosion. Hana ʻia ka lua i ka wā e pōʻino ai nā wahi kūloko ma luna o ka ʻili, e hōʻike ana i ka metala lalo i nā mea ʻino, ʻoiai ke kumu o ka ʻinoʻino ʻana i nā waihona i paʻa i nā āpau ma waena o ka ʻili.

Eia kekahi, hiki i ka 304 stainless steel ke hoʻomaʻamaʻa ʻia ke ʻike ʻia i nā mahana ma luna o 800°F (427°C), e alakaʻi ana i ka corrosion intergranular. No laila, he mea koʻikoʻi ka mālama ʻana i ka wela ma hope o ka welding a i ʻole machining e mālama i ka hana maikaʻi loa.

Ma muli o kona kūpaʻa maikaʻi loa i nā ʻano ʻino ʻino, ʻo 304 stainless steel ka mea i koho nui ʻia no nā ʻoihana he nui ka lōʻihi a me ka hilinaʻi i mea nui.

ʻO ka hoʻoponopono wela o 304 kila kila

ʻO ka hana wela he ʻenehana i hoʻohana ʻia e hoʻololi i ke kino a me ka mīkini waiwai o 304 kila kuhiliʻole ma lalo o nā kūlana wela kiʻekiʻe. ʻO kēia kaʻina hana e pili ana i ka hoʻomehana ʻana i ka mea i kahi mahana kikoʻī, e mālama ʻia i kēlā mehana no kekahi manawa, a laila hoʻomaha iā ia ma ke ʻano hoʻomalu.

ʻElua mau ʻano hana wela maʻamau no ka 304 stainless steel he annealing a quenching. ʻO ka Annealing ka hoʻomehana ʻana i ke kila a hiki i ka 1,900°F (1,038°C) a mālama ʻia i kēlā mehana no kahi manawa lōʻihi, a laila hoʻomoʻa mālie i loko o ka umu. Kōkua kēia kaʻina hana e hoʻomaha i nā koʻikoʻi o loko i loko o ka hale metala a hoʻonui i kona ductility.

ʻO ka Quenching kekahi ʻano hana e wela ai ka ʻāpana metala i kahi kūlana ʻulaʻula a laila hoʻokomo koke ʻia i ka wai a i ʻole ka aila. Hoʻokumu kēia kaʻina hana i kahi papa ʻili paʻakikī ma waho me ka mālama ʻana i kekahi degere o ka maʻalahi i loko o ka mea.

He mea nui ia e hoʻomaopopo he hiki i ka overheating ke hoʻololi i ka microstructure, e alakaʻi ana i ka embrittlement me ka hoʻohana ʻana i ka ikaika liʻiliʻi. Hiki ke hoʻonui i ka ikaika mechanical a me ka pale ʻana i ka corrosion ke hana pono ʻia me ka ʻole o nā hopena ʻino i nā waiwai ʻē aʻe.

Hoʻohana ʻia o 304 Stainless Steel

ʻO ka 304 stainless steel he mea hoʻoheheʻe nui me ke kūpaʻa corrosion maikaʻi loa, kūpono no nā noi like ʻole i nā ʻoihana like ʻole. ʻO kona hui pū ʻana o ka ikaika, ka lōʻihi, a me ka maʻalahi o ka hana ʻana he koho kūpono ia no nā huahana he nui.

1. 1. ʻO kekahi o ka hoʻohana nui ʻana o 304 stainless steel i ka hana ʻana. ʻO ke kūpaʻa kiʻekiʻe o ka ʻōpala a me nā waiwai anti-pollution e kūpono loa ia no ka hana ʻana i nā mea pono e kū i nā kūlana kūlohelohe koʻikoʻi me ka ʻole o ka hoʻohaʻahaʻa ʻana i ka manawa, e like me nā pahu mālama, nā paipu, nā valves, a me nā mea pono.
   2. Ma waho aʻe o ka hana ʻana, hoʻohana nui ʻia ka 304 stainless steel i ka ʻoihana meaʻai. He mea kūpono loa ia no ka lawelawe ʻana i nā meaʻai ʻakika a i ʻole nā ​​wai i loko o ka paʻakai a i ʻole ka vīneka.
   3. ʻO kekahi hoʻohana maʻamau o kēia huila i loko o nā papahana kūkulu, kahi e kūpono ai kona ikaika a me ka pale ʻana i ka corrosion no ke kūkulu ʻana i nā hale e like me nā alahaka, nā alahao, a me nā mea hana waho ʻē aʻe i ʻike ʻia i nā kumu o ka wā e like me ka ua a i ʻole ka ʻūhā kai.
   4. Ke hilinaʻi nui nei ka ʻoihana mālama ola i ka 304 stainless steel ma muli o kona biocompatibility, e kōkua ana i ka pale ʻana i ka ʻino i ka wā o nā kaʻina hana olakino. No laila, hiki ke ho'oma'ema'e pinepine 'ia nā mea hana i hana 'ia mai kēia mea me ka 'ino a ho'oha'aha'a paha i ka manawa.

No ka mea ʻoi aku ka maikaʻi o ka 304 stainless steel ma mua o nā mea ʻē aʻe e like me ke alumini a i ʻole ke kila kalapona ke hoʻohana pono ʻia, e hoʻomau nā mea hana i ka hoʻohana ʻana i ka 304 stainless steel no ka mea e mau ana ka ʻoluʻolu o ka mea kūʻai aku.

Panina

Mahalo iā ʻoe no ka heluhelu ʻana i kā mākou ʻatikala a ke manaʻo nei mākou e hiki ke kōkua iā ʻoe e ʻike maikaʻi i ka waiwai o 304 kila kuhiliʻole. Inā makemake ʻoe e ʻike hou aku e pili ana i ka 304 stainless steel, makemake mākou e kipa Kinohi Pilikino Sino.

Ma ke ʻano he alakaʻi alakaʻi o nā huahana stainless steel a puni ka honua, Kinohi Pilikino Sino hāʻawi i nā mea kūʻai aku me nā huahana kila kuhili kiʻekiʻe e like me 316L a me 316 Hot Rolled Kuhiliʻole Plate,  Nā kihi kila kila, Na Kanika Kuleana, 201 mau kaha hao hao & 304 Nā ʻAi Kuhili ʻole, 430 Na Papa Kuiliahi, Bara Hexagon Kuhiliʻole, ʻO ke kila kila i ʻōwili ʻia wela, Nā Pepa Kūleʻa Kūleʻa kala, ʻEleʻele Kūleʻa Kūleʻa Wili kala kila, a Nā Papa Kūleʻa Pilikino.
