No nā hale i hoʻopaʻa ʻia, makemake pinepine ʻia ʻo 304L a me 316L no ka mea ʻo ko lākou haʻahaʻa o ke kalapona e kōkua i ka hōʻemi ʻana i ka pilikia sensitization ma hope o ka hoʻopaʻa ʻana. Inā e hoʻopaʻa nui ʻia ka huahana a hoʻohana ʻia paha i ka lawelawe corrosion ma hope o ka hoʻopaʻa ʻana, pono nā mea kūʻai e hōʻoia inā pono ka papa L.

6. Pehea e hiki ai i nā mea kūʻai ke hōʻoia inā he 304 a i ʻole 316 ka mea?

Pono nā mea kūʻai e nānā i ka EN 10204 3.1 MTC, ka helu wela, ka hōʻailona huahana a me ka hoʻohuihui kemika. He mea pono loa ka hoʻāʻo ʻana o PMI no ka mea hiki iā ia ke hōʻoia i ka nui o ka chromium, nickel a me ka molybdenum. ʻO ke alo o ka molybdenum e kōkua i ka hoʻokaʻawale ʻana i ka 316 mai ka 304.

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

Pono i loko o kahi nīnau piha e komo pū me ke ʻano, ke kūlana, ke ʻano o ka huahana, ka nui, ka nui, ka hoʻopau ʻana o ka ʻili, ke ahonui, ke koi palapala hōʻoia, ke koi hoʻāʻo, ke awa i hoʻouna ʻia a me ke koi hoʻopili. No ka laʻana: ASTM A276 316L kila poepoe, ke anawaena 30 mm, ka lōʻihi 3000 mm, ka ʻili ʻālohilohi, koi ʻia ʻo EN 10204 3.1 MTC.

Hopena

Pono ke koho ma waena o ke kila kila 304 a me 316 e kau ʻia ma luna o ke kaiapuni pala, ke ʻano noi, ke ʻano huahana, ka hoʻopau ʻana o ka ʻili, ke koi wili, ke koi palapala hōʻoia a me ka waihona kālā. He koho kūpono ke kila kila 304 no nā lako maʻamau, ka hana ʻana i ka meaʻai, nā hale o loko, ka hoʻonaninani a me nā noi ʻoihana maʻamau. ʻOi aku ka maikaʻi o ke kila kila 316 no nā wahi kai, kahakai, kemika, lāʻau lapaʻau a me nā wahi i loaʻa ka chloride.

No nā kaola, nā pepa a me nā paipu, pono nā mea kūʻai e hōʻoia i ke kūlana ASTM a i ʻole EN kūpono, ka papa like, ka helu wela, EN 10204 3.1 MTC, ka hoʻāʻo ʻana o PMI, ka nānā ʻana i nā ana a me ka hoʻopili ʻana i waho ma mua o ka hoʻouna ʻana. Pono ka mea hoʻolako kila kila ʻoihana e kōkua i nā mea kūʻai e hoʻohālikelike i nā mea, e pale i ka lako papa hewa a koho i kahi papa e kaulike ana i ke kūpaʻa ʻana i ka pala, ka hana mechanical a me ke kumukūʻai.
