ʻO ka papa 316 ka papa molybdenum-bearing maʻamau, ka lua o ka mea nui i ka 304 ma waena o nā kila kuhili ʻole austenitic.Hāʻawi ka molybdenum i 316 mau waiwai kūpaʻa ʻoi aku ka maikaʻi ma mua o ka Papa 304, ʻoi aku ka kiʻekiʻe o ke kūʻē ʻana i ka lua a me ka crevice corrosion ma nā kaiapuni chloride.

Papa 316L, ka mana kalapona haʻahaʻa o 316 a ua pale ʻia mai ka ʻike ʻana (ka ua carbide palena ʻai).No laila, hoʻohana nui ʻia ia i nā ʻāpana welded anana kaumaha (ma kahi o 6mm).ʻAʻohe ʻokoʻa kumu kūʻai maʻamau ma waena o 316 a me 316L kila kila.

Hāʻawi ka ʻōnaehana austenitic i kēia mau māka i ka paʻakikī maikaʻi loa, a hiki i nā mahana cryogenic.

Ke hoʻohālikelike ʻia me nā kila kila chromium-nickel austenitic, hāʻawi ʻo 316L stainless steel i ke kolo kiʻekiʻe, ke koʻikoʻi i ka haki ʻana a me ka ikaika tensile i nā wela kiʻekiʻe.

Na Waiwai Ki

Kuhi ʻia kēia mau waiwai no ka huahana ʻōwili palahalaha (pālaʻi, pepa a me ka coil) ma ASTM A240/A240M.Ua kuhikuhi ʻia nā waiwai like akā ʻaʻole like no nā huahana ʻē aʻe e like me ka paipu a me ka bar i kā lākou mau kikoʻī.

Huina

Papa 1. Nā pae hoʻohui no nā kila kila 316L.

Na Waiwai Mechanical

Papa 2. Mechanical waiwai o 316L kuhiliʻole kila.

Na Waiwai Kino

Papa 3.ʻO nā waiwai kino maʻamau no nā kila kila kila 316.

Hoʻohālikelike Hoʻohālikelike Papa

Papa 4.Nā kikoʻī kikoʻī no nā kila kila 316L.

'Ōlelo Aʻo: ʻO kēia mau hoʻohālikelike he mea pili wale nō.Ua manaʻo ʻia ka papa inoa ma ke ʻano he hoʻohālikelike o nā mea hana like ʻole ma ke ʻano he papa hana o nā mea like aelike.Inā makemake ʻia nā mea like pono e nīnau ʻia nā kikoʻī kumu.

Nā Papa ʻē aʻe

Papa 5. Loaʻa nā helu ʻokoʻa i ka 316 kila kila.

Papa 5.Hiki i nā māka ʻē aʻe i ka 316 kila kila.

Papa

No ke aha e koho ʻia ai ma kahi o 316?

317L

ʻOi aku ka nui o ka pale ʻana i nā chlorides ma mua o 316L, akā me ke kūpaʻa like ʻana i ke koʻikoʻi o ka corrosion cracking.

Pale ʻino

Maikaʻi i nā ʻano o nā kaiapuni lewa a me nā mea hoʻoheheʻe ʻino - ʻoi aku ke kūpaʻa ma mua o 304. E pili ana i ka lua a me ka ʻāʻī ʻana i loko o nā kaiapuni chloride mahana, a me ke koʻikoʻi i ka pohā ʻino ma luna o 60°C. Manaʻo ʻia ʻaʻole kūʻē i ka wai inu a hiki i ka 1000mg/L chlorides ma nā mahana ambient, e hōʻemi ana ma kahi o 500mg/L ma 60°C.

Manaʻo ʻia ʻo 316 ma ke ʻano maʻamau“kila kila kila”, akā, ʻaʻole ia e kū i ka wai mehana o ke kai.Ma nā kaiapuni moana he 316 e hōʻike ana i ka ʻino o ka ʻili, ʻike pinepine ʻia e like me ke kala ʻeleʻele.Pili pono kēia me nā māwae a me ka pau ʻana o ka ʻili.

Kū'ē wela

ʻO ke kūpaʻa oxidation maikaʻi i ka lawelawe intermittent i 870°C a ma ka lawelawe mau ana i 925°C. Hoʻohana mau i ka 316 ma ka 425-860°ʻAʻole ʻōlelo ʻia ka laulā C inā he mea nui ka pale ʻana i ka ʻino wai.ʻOi aku ka paʻa o ka papa 316L i ka ua carbide a hiki ke hoʻohana ʻia i ka pae wela o luna.Loaʻa ka ikaika kiʻekiʻe o ka papa 316H i nā mahana kiʻekiʻe a hoʻohana ʻia i kekahi manawa no ka hoʻolālā ʻana a me nā noi paʻi i nā mahana ma luna o 500.°C.

Hoʻomaʻamaʻa Wela

Hoʻoponopono Hoʻoponopono (Annealing) - Wela i 1010-1120°C a hoʻolili koke.ʻAʻole hiki ke hoʻopaʻakikī ʻia kēia mau māka e ka mālama wela.

wiliwili

ʻO ka weldability maikaʻi loa e nā ʻano fusion maʻamau a me nā ʻano kūʻē, me nā metala hoʻopiha a me ka ʻole.Pono nā ʻāpana welded kaumaha ma ka Papa 316 i ka hoʻopili ʻana ma hope o ka weld no ka pale ʻana i ka corrosion kiʻekiʻe.ʻAʻole koi ʻia kēia no 316L.

ʻAʻole hiki ke wiliwili ʻia ke kila kila 316L me ka hoʻohana ʻana i nā ʻano hoʻoheheʻe oxyacetylene.

Mīkini

ʻO 316L ke kila kila e hana paʻakikī inā wikiwiki ka mīkini.No kēia kumu, ua ʻōlelo ʻia nā wikiwiki haʻahaʻa a me nā uku hānai mau.

ʻOi aku ka maʻalahi o ka 316L stainless steel i ka mīkini i hoʻohālikelike ʻia me 316 stainless steel ma muli o kona ʻano kalapona haʻahaʻa.

Hana Wela a Anu

Hiki ke hana wela ka 316L me ka hoʻohana ʻana i nā ʻenehana hana wela maʻamau.ʻO nā mahana wela hana maikaʻi loa ma ka laulā 1150-1260°C, a ʻaʻole pono e emi iho ma mua o 930°C. Pono e hana ʻia ka hoʻopili ʻana ma hope o ka hana i mea e hoʻoulu ai i ka pale ʻana i ka corrosion.

ʻO ka hapa nui o nā hana anu maʻamau e like me ka ʻako ʻana, ke kaha kiʻi a me ke kaha ʻana i hiki ke hana ʻia ma 316L kila kila.Pono e hana ʻia ka annealing ma hope o ka hana no ka wehe ʻana i nā kaumaha o loko.

Hoopaakiki a me ka hana paakiki

ʻAʻole paʻakikī ʻo 316L kila kila ma ka pane ʻana i ka mālama wela.Hiki ke hoʻopaʻakikī ʻia e ka hana anu, hiki ke hoʻonui i ka ikaika.
