ʻIke ʻoe i ka 316 a me 316L stainless steel i kuhikuhi ʻia i nā manawa āpau, akā ʻo ka ʻokoʻa maoli ʻaʻole ia he leka wale nō ma kahi ʻikepili. Aia i loko o nā weld, nā lua ʻino, a me nā ʻāpana e hoʻi mai ana mai ke kula. Nui ka poʻe i manaʻo he hiki ke hoʻololi. ʻAʻole lākou, a ua ʻike wau i ka manaʻo kumu kūʻai.
Ka Maʻiʻo Carbon: ʻAʻole ia he helu wale
ʻO ka ʻokoʻa kumu ka carbon. Loaʻa iā 316 ka nui o 0.08%, ʻoiai 316L kila kila He 0.03% ka nui. He mea liʻiliʻi paha, ʻeā? Ma ke kumumanaʻo, malia paha. Akā ma ka hoʻomaʻamaʻa, makemake kēlā kalapona e hui pū me ka chromium i ka wā wili, e hana ana i nā chromium carbide pololei ma nā palena o ka palaoa. ʻAhuhi kēia ʻike i ka chromium e hāʻawi i ke kila i kona pale ʻana i ka corrosion, e waiho ana i kahi ala palupalu ma ka ʻāpana weld wela. No kahi ʻāpana e noho wale ana ma laila, maikaʻi paha. No kēlā me kēia mea e kū ana i nā chlorides a i ʻole nā waikawa, he wahi hāʻule i hoʻokomo mua ʻia.
Hoʻomanaʻo wau i kahi pūʻulu o nā kino valve no ka mea kūʻai aku i ka hoʻoponopono kemika. Ua ʻōlelo ʻia ka paʻi 316 stainless. ʻO ka hale kūʻai, e hoʻāʻo ana e mālama i kekahi mau kālā no ka kilo, ua hoʻohana i ka waihona 316 bar maʻamau. Ua hana maikaʻi ʻia nā ʻāpana, ua hala i ka nānā mua ʻana. Akā i ʻeono mahina ma hope mai, ua loaʻa iā mākou nā kiʻi: maikaʻi, nā māwae me ka punawelewele e puka mai ana mai kēlā me kēia wili weld. ʻinoʻino waena. ʻO ka mea kūʻai aku, maopopo, huhū. ʻO ia ka manawa āu e aʻo ai e nīnau koke: E welded anei kēia? He aha ke kaiapuni lawelawe? Inā he ʻae ka pane i ka wiliwili, koi ʻoe no ka papa L. ʻAʻohe paio.
ʻO kēia ke kumu he mea nui ka hiki ʻana o ka mea hoʻolako. ʻO kahi hui like QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD. (QSY), me kā lākou mau makahiki ʻekolu i ka hoʻolei ʻana a me ka mīkini, e loaʻa kēia. Ke hana nei ʻoe hoʻolei kālā a i ʻole ʻO ka mīkini CNC ʻO nā ʻāpana e lilo i ʻāpana o kahi hui welded ʻoi aku ka nui, e hoʻomaka me ka haʻahaʻa carbon grade ʻaʻole ia he koho-ʻo ia wale nō ke koho maʻemaʻe. ʻO kā lākou ʻike me nā mea hoʻoheheʻe kūikawā ʻo ia hoʻi, ua ʻike mua lākou i nā hopena o nā hemahema waiwai.
Machinability and Formability: The Shop Floor Reality
E kamaʻilio kākou e pili ana i ke ʻoki a me ke ʻano. ʻAʻole ʻo 316 a i ʻole 316L ka moeʻuhane o ka mea mīkini—he ʻāʻī lākou, hana-paʻakikī lākou e like me ka pupule inā ʻaʻole ʻoe e makaʻala. Akā ma waena o nā mea ʻelua, hāʻawi wau i kahi kihi liʻiliʻi i 316L no ka paʻa ʻana o ka mīkini i nā ʻāpana paʻakikī. ʻO ke kalapona haʻahaʻa e like me ka hopena o ka haki ʻana o ka chip, ʻoi aku ka liʻiliʻi o ka lihi i kūkulu ʻia ma luna o ka hāmeʻa, ʻoi aku hoʻi i nā hana hoʻomau e like me ka hoʻohuli ʻana i nā profiles no nā impellers pump.
No ka hana ʻana a i ʻole ke kala ʻana, ʻoi aku ka nui o ka kala ʻana o 316L. ʻO kona ikaika haʻahaʻa haʻahaʻa a me ka ductility kiʻekiʻe i ka hoʻomaka ʻana e maʻalahi ke kaomi ʻana i ka paʻakikī hoʻoheheʻe ʻia ʻana o ka pūpū nā hiʻohiʻona me nā pilikia springback. Pono mākou e huki hohonu i kekahi mau kīʻaha pā lahilahi mai ka pepa 316. ʻO ka holo mua me ka maʻamau 316 i loaʻa i ka 30% ka nui o ka ʻōpala mai nā micro-cracks ma ka radius huki. Ua hoʻololi ʻia i ka 316L, a ua nalowale ka pilikia. Ua holo maikaʻi ka mea.
He wahi koʻikoʻi kēia no nā mea hana. Inā ʻoe e ʻimi nei i nā castings i hana mua ʻia a i ʻole nā pololei i hana ʻia, ʻo ka wehewehe ʻana i ka māka kūpono no ke kaʻina hana hana ʻo ia ka hapalua o ke kaua. He hoa hoʻomaopopo i ke kaʻina hana, e like me kāu e ʻike ai tsingtaocnc.com, ʻaʻole kūʻai wale aku iā ʻoe i ka metala; ke noi nei lākou i kā lākou ʻO ka mīkini CNC a me ka hoʻolei ʻana i ka ʻike no ke koho ʻana i ka papa e ʻike maopopo ʻia ma lalo o kā lākou mau mea hana a me nā poni, e mālama ai i nā poʻo o kēlā me kēia ma lalo o ka laina.
ʻO ka moʻolelo koʻikoʻi a me ka ʻoiaʻiʻo Molybdenum
ʻO ka moʻolelo maʻamau ʻo 316L ʻoi aku ka pale ʻana i ka corrosion ma mua o 316. ʻAʻole pololei. ʻO ko lākou kumu kū'ē, i hāʻawiʻia e kēlā 2-3% molybdenum a me ka chromium-nickel matrix, ua like ia i ka annealed, non-welded state. ʻO ka molybdenum ke kī—ʻo ia ka mea e hoʻopaʻa ai i ke kūʻē ʻana i ka lua a me ka crevice corrosion i loko o nā kaiapuni chloride ma luna o 304. ʻO ka pono o ka papa L ʻo ia wale nō ka mālama ʻana i kēlā kūʻē kūʻokoʻa ma hope o nā pōʻai wela e like me ka wili.
Eia naʻe kahi nuance: i loko o nā waikawa oxidizing nui (e like me ka nitric), hiki ke hoʻololi i ka moʻolelo. Aia kekahi mau ʻikepili a me nā hōʻike anecdotal mai nā lima kahiko e hiki i ka maʻamau 316 ke hana i kekahi manawa ʻoi aku ka maikaʻi ma kēia mau wahi kikoʻī, non-chloride. ʻO kekahi mea e pili ana i ka paʻa kiʻiʻoniʻoni passive. ʻAʻole wau i pili i kahi papahana ma ia mea, akā he mea hoʻomanaʻo ia ʻaʻole paʻa loa ka ʻepekema waiwai. Pono ʻoe e ʻike i ka ʻenemi pololei e kū nei ka ʻāpana.
No nā noi hoʻoponopono kai maʻamau, kemika, a i ʻole nā meaʻai - kahi i loaʻa ai nā chlorides, nā ʻakika organik, a i ʻole nā mea hoʻonā sterilizing-ʻo ka maikaʻi welded o 316L kila kila lilo ia i mea paʻamau. ʻO ia ke koho palekana a ʻoi aku ka maʻalahi no nā mea hana i hana ʻia. Ke nānā au i ka waihona waiwai o kahi loea e like me QSY, e komo pū ana kēia mau mea kila a me nā nickel-based alloys no nā hana ʻoi aku ka koʻikoʻi, hōʻailona ia ua maʻa lākou i ka hana ʻana i kēia mau nuanced, nā kikoʻī noiʻi noiʻi, ʻaʻole wale ka neʻe ʻana i nā waihona metala generic.
Ke Kumukuai a me ke Kumu: Ka Helu Ma'amau
ʻAe, lawe pinepine ʻo 316L i kahi uku liʻiliʻi. Akā, ʻaʻole naʻaupō kēlā loiloi kumukūʻai inā kū ia ma ka invoice maka. Pono ʻoe e helu i ke kumukūʻai o ka hana a me ke ola. Inā hoʻohana ʻoe i ka 316 maʻamau, pono ʻoe e hoʻohui i nā welds e hoʻoheheʻe i nā carbide (he ʻanuʻu ʻē aʻe, kumukūʻai, a hoʻololi pinepine ʻia), a i ʻole ʻoe e pilikia i nā hemahema o ke kahua, hoʻololi koke ka makemakika. Hoʻopau pinepine ka papa L i ka pono o ka mālama wela post-weld.
ʻO ka loaʻa ʻana kekahi mea ʻē aʻe. Me ka hoʻoikaika honua no ka standardized, weldable structural stainless, 316L ʻoi aku ka maʻalahi o ka loaʻa ʻana ma kahi ākea o nā ʻano - ka pā, ka paipu, nā mea pono, ka hoʻolei ʻana-ma mua o ka 316 maʻamau.
Hāʻawi kēia loaʻa i nā kaulahao lako hilinaʻi no nā mea hana. ʻO kahi hana lōʻihi, e like me Qingdao Qiangsenyuan Technology Co., Ltd., e hoʻoikaika ana i nā mea like. kila kila a me nā huila kūikawā, ua hoʻokumu paha i nā ala no nā māka kūpono. Hōʻike kā lākou moʻolelo he 30 mau makahiki ua kūkulu lākou i nā pilina no ke kumu ʻaʻole metala wale nō, akā ʻo ka metala kūpono no ka hana, ʻo ia ka mea ʻoi aku ka paʻakikī.
Hoʻoholo no ka noi: ʻO ka manawa hea e hoʻohana ai
No laila, he lula maʻalahi: inā e welded a kū i kahi lawelawe corrosive, hoʻohana 316L kila kila. Kū piha. Hoʻopili kēia i ka 90% o nā noi ʻoihana - nā ʻōnaehana paipu, nā moku kaomi, nā mīkini hana meaʻai, nā lako kai, nā pahu lāʻau lapaʻau. ʻO ka hilinaʻi ʻē aʻe ke kūpono i ka ʻokoʻa kumu kūʻai liʻiliʻi.
I ka manawa hea ʻoe e noʻonoʻo ai i ka maʻamau 316? No nā ʻāpana ʻaʻole welded, a i ʻole nā noi kahi e hopohopo nui ai ka ikaika wela (ma luna o 800 ° F), no ka mea hiki i ke kalapona kiʻekiʻe ke hāʻawi i ka ikaika kolo. E noʻonoʻo i kekahi mau ʻāpana o ka umu ahi, nā kumu i hoʻopaʻa ʻole ʻia, a i ʻole kekahi mau mea paʻa. Akā naʻe, ke kālepa nei ʻoe i kahi pōmaikaʻi wela kiʻekiʻe no ka hoʻopaʻi weldability paʻa. He koho niche.
ʻO ka hope loa, hele mai ia i ka ʻike kikoʻī. ʻAʻole ia no ka maikaʻi o ka papa hoʻokahi, akā ʻoi aku ka kūpono o kekahi. ʻO ka pahuhopu ka hoʻohālikelike ʻana i nā waiwai ponoʻī o ka mea i ke kaʻina hana a me ka hoʻohana ʻana i ka hoʻohana hope. ʻO ia ke ʻano o ka hoʻoholo kūpono e hoʻokaʻawale i ka mea hoʻolako ʻāpana mai kahi hoa hana maoli. ʻO ia ka ʻokoʻa ma waena o ka hana ʻana i ke ʻano a me ka hāʻawi ʻana i kahi mea hana, a mau loa, i ke ao maoli.
