He aha ka ʻokoʻa ma waena o 304 a me 316 paipu kila kila?

Hoʻohana nui ʻia nā paipu kila kila i nā ʻoihana like ʻole ma muli o ko lākou lōʻihi, ke kūpaʻa corrosion, a me ka ikaika kiʻekiʻe. ʻElua ʻano maʻamau o nā paipu kila kila ʻo 304 a me 316. ʻOiai ua hana ʻia nā mea ʻelua i ke kila kila, aia kekahi mau ʻokoʻa nui ma waena o lākou. Eia ka haʻihaʻi o nā ʻokoʻa nui ma waena o 304 a me 316 mau paipu kila kila.

 

Huina

ʻO ka ʻokoʻa nui ma waena o 304 a me 316 mau paipu kila kila ma kā lākou haku mele. Hana ʻia nā mea ʻelua i ka hao, chromium, a me nickel, akā ʻo 316 stainless steel ka molybdenum hou. Hāʻawi kēia ʻike molybdenum hou i ka 316 stainless steel i kona kūpaʻa corrosion kiʻekiʻe i hoʻohālikelike ʻia me 304.

 

Pale ʻino

ʻIke ʻia ʻo 304 stainless steel no kona kūpaʻa ʻana i ka corrosion maikaʻi, kūpono ia no nā noi i loko a me waho. Akā naʻe, ʻaʻole ia e like me ka corrosion e like me 316 stainless steel. ʻO 316 mea i hoʻohui ʻia i ka molybdenum i hoʻohui ʻia e ke kila kila, ʻoi aku ka pale ʻana i ka chloride corrosion, ʻo ia hoʻi, ʻoi aku ka maikaʻi no nā kaiapuni kai a me nā wahi ʻino nui.

 

Nā noi

Ma muli o kona kūpaʻa ʻana i ka corrosion maikaʻi, hoʻohana pinepine ʻia ʻo 304 stainless steel i nā noi e like me nā lako kīhini, nā mea hana meaʻai, a me kekahi mau hana hoʻolālā. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka maikaʻi o ka 316 stainless steel i nā wahi ʻoi aku ka koʻikoʻi e like me ka hoʻoponopono kemika, nā noi kai, a me nā mea hoʻokomo ʻokiʻoki ma muli o kona kūpaʻa ʻana i ka corrosion.

 

Koina

ʻOi aku ka maʻalahi o ka 304 stainless steel ma mua o 316 stainless steel ma muli o kāna hana maʻalahi a me ka hoʻohana ākea. Inā ʻoe e ʻimi nei i kahi koho kumu kūʻai e hāʻawi mau ana i ka pale ʻana i ka corrosion maikaʻi, ʻoi aku ka maikaʻi o ka 304 stainless steel. Eia nō naʻe, inā makemake ʻoe i ke kiʻekiʻe kiʻekiʻe o ke kūpaʻa corrosion no kahi noi kikoʻī, ʻoi aku ka maikaʻi o ka 316 stainless steel i ke kumu kūʻai.

 

I ka hōʻuluʻulu ʻana, aia nā ʻokoʻa nui ma waena o 304 a me 316 mau paipu kila kila ma kā lākou haku mele ʻana, ka pale ʻana i ka corrosion, a me nā noi. Hāʻawi ʻo 304 stainless steel i ka pale ʻana i ka corrosion maikaʻi a ʻoi aku ka maikaʻi o ke kumukūʻai, ʻoiai ʻo 316 stainless steel ʻoi aku ka maikaʻi o ka corrosion ma muli o kāna ʻike molybdenum hou. Ke koho ʻana ma waena o nā mea ʻelua, e noʻonoʻo i nā koi kikoʻī o kāu noi a me ke kiʻekiʻe o ke kūpaʻa corrosion āu e pono ai.
