Eia nō naʻe, no nā ʻano kaiapuni kūpono, lawa paha ka 316L a ʻoi aku ka hoʻokele waiwai. No ka lawelawe koʻikoʻi loa, hiki ke noʻonoʻo ʻia ka super duplex 2507 a i ʻole nā ​​​​​​mea hoʻohui nickel.

4. ʻOi aku ke kumukūʻai o 2205 ma mua o 316L?

I nā hihia he nui, ʻoi aku ke kumukūʻai o 2205 ma mua o 316L ma muli o ka nui o ka metala, ka kaohi hana a me ka pae hana. Eia nō naʻe, hiki iā ia ke hōʻemi i ke kumukūʻai holoʻokoʻa o ke ola ma nā wahi chloride ʻino no ka mea hiki iā ia ke hāʻawi i ke ola lawelawe lōʻihi a me ka ikaika mechanical kiʻekiʻe.

5. Hiki ke hoʻopili ʻia ke kila kila duplex 2205?

ʻAe, hiki ke hoʻopili ʻia ka 2205, akā pono ka hoʻopili ʻana o ka duplex i ka mana hoʻokomo wela kūpono, ke koho ʻana i ka mea hoʻopihapiha a me ka hoʻokele kaulike ferrite/austenite. ʻOi aku ka maʻalahi o ka hoʻopili ʻana i ka 316L, akā makemake ʻia ka 2205 ke koi ʻia ka ikaika kiʻekiʻe a me ke kū'ē ʻana o ka chloride.

6. Pehea e hiki ai i nā mea kūʻai ke hōʻoia inā he 2205 a i ʻole 316L ka mea?

Pono nā mea kūʻai e nānā iā EN 10204 3.1 MTC, ka helu wela, ka helu UNS, ka hoʻohuihui kemika a me ka māka huahana. Paipai ikaika ʻia ka hoʻāʻo PMI no ka mea hiki iā ia ke hōʻoia i ka nui o ka chromium, nickel a me ka molybdenum a kōkua i ka ʻike ʻana i ke ʻano kila kila kūpono.

7. He aha ka ʻike e pono ai no kahi ʻōlelo wikiwiki?

Pono i loko o kahi nīnau piha ke ʻano, ka helu UNS, ke kūlana, ke anawaena, ka lōʻihi, ka nui, ka hoʻopau ʻana o ka ʻili, ke ahonui, ke koi hoʻāʻo, ke koi MTC, ke awa hoʻouna a me ke koi hoʻopili. No ka laʻana: ASTM A276 UNS S32205 2205 ʻauamo poepoe kila kila duplex, ke anawaena 35 mm, ka lōʻihi 3000 mm, ka ʻili i ʻili ʻia, EN 10204 3.1 MTC a me ka hoʻāʻo PMI e pono ai.

Hopena

ʻO 2205 Duplex Stainless Steel Bar a me 316L Stainless Steel Bar he mau mea kila kila koʻikoʻi e kū i ka pala, akā ua koho ʻia lāua no nā kūlana lawelawe like ʻole. He kūpono ʻo 316L no nā ʻāpana ākea e kū i ka pala, nā lako meaʻai a me nā lāʻau lapaʻau, nā ʻāpana mīkini maʻamau a me nā noi koʻikoʻi. He kūpono ʻo 2205 no nā ʻāpana ikaika kiʻekiʻe, nā wahi chloride, nā lako moana, nā ʻōnaehana desalination, nā noi aila a me ke kinoea a me nā ʻāpana e pono ai ke kū'ē maikaʻi i ka haki ʻana o ka palaho.

No ke kūʻai kūleʻa ʻana, pono nā mea kūʻai e hōʻoia i ka māka, ka helu UNS, ke kūlana ASTM a i ʻole EN, ka nui o ka pā, ke ahonui, ka hoʻopau ʻana o ka ʻili, EN 10204 3.1 MTC, ka mana helu wela, ka hoʻāʻo ʻana o PMI, ka hoʻāʻo ʻana o UT, ka nānā ʻana i nā dimensional a me ka hoʻopili ʻana i waho. Pono ka mea hoʻolako kila kila ʻoihana e kōkua i nā mea kūʻai e hoʻohālikelike i ke kūpaʻa ʻana i ka pala, ka ikaika a me ke kumukūʻai ma mua o ke koho ʻana i ka pā kila kila duplex 2205 a i ʻole ka pā kila kila 316L.
