ʻAno 304 a me 304L Kūleʻa kila

Hoʻopaʻa ʻia kēlā me kēia ʻano kila kila, maʻamau i ka moʻo. Hoʻokaʻawale kēia mau pūʻulu i nā ʻano ʻano ʻano kulika mai 200 a 600, me nā ʻāpana he nui i waena. Hele mai kēlā me kēia me nā waiwai ʻokoʻa a hāʻule i loko o nā ʻohana e like me:

• austenitic:non-magnetic
• ferritic: mākini
• duplex
• martensitic a me ka ua paakiki:ikaika kiʻekiʻe a me ke kū'ē maikaʻi i ka corrosion

Maanei, wehewehe mākou i ka ʻokoʻa ma waena o ʻelua mau ʻano maʻamau i loaʻa ma ka mākeke - 304 a me 304L.

ʻO Type 304 ka mea austenitic i hoʻohana nui ʻiakuhiliʻolekila. Ua ʻike ʻia ʻo ia ʻo "18/8" kila kila ma muli o kāna haku mele ʻana, aia ka 18%chromiuma me 8%nikela. Loaʻa i ka ʻano 304 stainless steel maikaʻi ka hoʻokumu ʻana a me nā waiwai wili a me ka ikaikaʻinoʻinoke kū'ē a me ka ikaika.

Loaʻa i kēia ʻano ʻano kila kila maikaʻi. Hiki ke hana ʻia i loko o nā ʻano ʻano like ʻole a, ʻokoʻa me ke ʻano 302 stainless, hiki ke hoʻohana ʻia me ka ʻole o ka annealing, ka hoʻomaʻamaʻa wela e hoʻomāmā i nā metala. Loaʻa nā hoʻohana maʻamau no ke kila kila kila ʻano 304 i ka ʻoihana meaʻai. He kūpono no ka hana ʻana i ka waiu, ka hana ʻana i ka waiū, a me ka hana waina. He kūpono no nā paipu, nā pā hū, nā pahu fermentation, a me nā pahu mālama.​

Loaʻa ʻia ke kila kila kila ʻano ʻano 304 i loko o nā poho, nā papa papa, nā ipu kofe, nā pahu hau, nā kapuahi, nā ipu, a me nā mea hana kuke ʻē aʻe. Hiki iā ia ke pale i ka ʻino i hiki ke hana ʻia e nā kemika like ʻole i loaʻa i loko o nā huaʻai, ka ʻiʻo, a me ka waiū. ʻO nā wahi ʻē aʻe o ka hoʻohana ʻana e pili ana i ka hoʻolālā ʻana, nā ipu kemika, nā mea hoʻololi wela, nā mea hana mining, a me nā nati moana, nā bolts, a me nā screws. Hoʻohana ʻia ʻo Type 304 i nā ʻōnaehana hoʻoheheʻe wai a me ka ʻoihana kala.

ʻO ke kila kila 304L ʻano he ʻano kalapona haʻahaʻa haʻahaʻa o ke kila 304huikau. ʻO ka haʻahaʻa kalapona ma 304L e hōʻemi i ka ua carbide pōʻino a ʻino paha ma muli o ka wili. No laila, hiki ke hoʻohana ʻia ʻo 304L "e like me ka welded" i nā wahi ʻino koʻikoʻi, a hoʻopau ia i ka pono no ka annealing.

He haʻahaʻa haʻahaʻa haʻahaʻa kēia papa ma mua o ka papa 304 maʻamau, akā hoʻohana nui ʻia no kona versatility. E like me ka Type 304 stainless steel, hoʻohana maʻamau ia i ka hana pia a me ka hana waina, akā no nā kumu ma waho aʻe o ka ʻoihana meaʻai e like me nā ipu kemika, mining, a me ke kūkulu ʻana. He kūpono ia no ka hoʻohana ʻana i nā ʻāpana metala e like me nā nati a me nā bolts i ʻike ʻia i ka wai paʻakai.
