ʻO ka hoʻomaopopoʻana i ka 316L Stainless Steel: Hoʻohui, Pono, a me nā noi

Kū'ē Kū'ē Kū'ē: ʻO 316L ke kūpaʻa loa i ka ʻōpala a me ka ʻinoʻino, ʻoi aku ka paʻakai a i ʻole nā ​​​​kaiapuni paʻakikī. Kōkua ʻo Molybdenum i ka pale ʻana i ka lua a me ka hoʻouka ʻana. ʻO kēia ka 316L kūpono no nā lako kai, nā pahu kemika, a me ka hoʻolālā kahakai, kahi e maʻa mau ai ka chloride.

Ikaika Mahana Kiekie: Mālama ia i ka ikaika a me ke kūpaʻa i nā mahana kiʻekiʻe. 'A'ole e like me kekahi mau alalai, 316L 'a'ole e ho'olili ma lalo o ka wela. Hoʻohana maʻamau ia i nā mea hoʻololi wela, nā ʻāpana umu ahi, a me nā ʻāpana pauka kaʻa, e mālama pono ana i nā haneli degere Celsius. (Hoʻomaopopo ʻo Goodfellow he 316L alloys "e hōʻike i ka pale ʻana i ka corrosion maikaʻi a me ka paʻa ʻana o ka ikaika ma nā wela kiʻekiʻe".)

Weldability maikaʻi loa: Mahalo i kāna kalapona haʻahaʻa loa, hiki ke wili ʻia ʻo 316L me ka ʻole o ka annealing kūikawā e pale aku i ka sensitization. ʻO ke kalapona haʻahaʻa e hoʻemi i ka ua carbide ma nā palena palaoa i ka wā wili. ʻO ka hopena, ʻo nā hui welded e kū i ka corrosion. ʻO kēia maʻalahi o ka hana ʻana e hoʻohaʻahaʻa i nā kumukūʻai hana a me ka mālama ʻana ma hope o ka weld. No laila ʻoi aku ka maikaʻi ma mua o 316 no nā hale welded paʻakikī e like me nā pahu a me nā moku kaomi.

Biocompatibility a me Non-Reactive: ʻO 316L ka maʻamau inert a hypoallergenic. Hoʻohana nui ʻia ia i nā implants lapaʻau a me nā mea hana meaʻai no ka mea ʻaʻole ia e pane me nā ʻiʻo, nā lāʻau lapaʻau, a me nā meaʻai. (Hoʻomaopopo ʻo Spinnaker Watches ʻaʻole hiki i ka 316L ke hoʻonāukiuki i ka ʻili, ʻo ia ke kumu i kaulana ai nā mea lole lōʻihi e like me nā wati luʻu.)

Aesthetic a hoʻopau: Hiki ke hoʻonaniʻia kēia kila i kahi'ōniʻoniʻo a iʻole i kāhiliʻia no ka nānā satin. Kū'ē ia i ka palahu a mālama i kahi hiʻohiʻona nani i ka wā. He mea maʻalahi kona ʻili maʻemaʻe, ʻaʻohe porous e hoʻomaʻemaʻe, kahi hiʻohiʻona makemake no nā mea kūʻai aku a me nā noi hoʻomaʻemaʻe.

Ka lōʻihi a me ka hilinaʻi: ʻO ka holoʻokoʻa, hāʻawi ʻo 316L i ka hilinaʻi lōʻihi. ʻO ka hoʻonui ʻia ʻana o kona pale ʻana i ka intergranular corrosion (sensitization) a me ka haʻahaʻa haʻahaʻa o ka pitting, ʻo ia hoʻi, ʻo nā mea i hala i nā makahiki he mau makahiki i hala a i nā kūlana paʻakikī.. ʻOiai he haʻahaʻa iki kona tensile a hāʻawi i ka ikaika ma mua o ka maʻamau 316 (no ka liʻiliʻi o ke kalapona), ma ka hapanui o nā noi he mea liʻiliʻi kēia tradeoff a ua ʻoi aku kona kaumaha ma mua o kāna hana weldability a me ka hana corrosion.

ʻO 316L a me 316 mau kila kuhiliʻi like loa me ke kemika – ʻo lāua ʻelua mau ʻāpana austenitic me ka chromium, nickel, a me ka molybdenum. ʻO ka ʻokoʻa nui ʻano kalapona:

• kalapona: Loaʻa i ka 316L ka ≤0.03% kalapona, akā hiki i ka 316 ke loaʻa i ka 0.08%. Hoʻemi nui kēia kalapona haʻahaʻa i ka manawa o ka hoʻokumu ʻana o ka chromium carbide i ka wā wili.

• Weldability: ʻO ka liʻiliʻi o 316L carbide precipitation 'o ia hoʻi, ʻaʻole ʻike ʻia ma hope o ka weld, no laila e kū mau nā wahi wili i ka corrosion. ʻO ka mea like ʻole, hiki i ka welded 316 ke hoʻomohala i ka "weld decay" me ka ʻole o ka mālama wela kūpono.

• Paʻa ʻino: Kūleʻa maikaʻi nā kila ʻelua i ka corrosion, akā ʻoi aku ka maikaʻi o 316L i nā kaiapuni chloride a ma hope o ke kuʻi ʻana. ʻOi aku ka maʻalahi o ka Welded 316 i ka ʻōpala i nā ʻāpana wela.

• ikaika: Ma muli o ke kalapona ʻokoʻa, ʻoi aku ka ʻoi aku o ka ikaika o ka tensile/hua i kekahi manawa ma mua o 316L. Ma ka hoʻomaʻamaʻa he liʻiliʻi kēia ʻokoʻa. I ka nui o nā noi (me ka hana kaumaha a me ka hoʻohana ʻana i ka hoʻohana ʻana), ua lawa ka ikaika o 316L.

• Hoʻohana maʻamau: Ma keʻano laulā, koho ʻia ʻo 316L no kai, kemika, a me ka lapaau nā noi kahi e pono ai ka pale ʻana i ka corrosion a me ka weldability. Hoʻohana pinepine ʻia ka 316 maʻamau i ʻoihana, hana ʻai, a me ka hana maʻamau kahi i emi pinepine ai ka wiliwili a i ʻole ke kumu ʻino loa.
