AISI 316L Stainless Steel Gearbox hale e ka hoʻolei kālā

Mea Hoʻolauna a me nā pono

E like me ka crystallization o ka ʻenehana hana hana ʻenehana hou, ʻo ka AISI 316Lhoʻolei ʻana i ke kila kilaʻAʻole hōʻike wale ka hale pahu pahu i ka nani kūʻokoʻa o ke kila kila kila AISI 316L, akā hoʻokō pū kekahi i ka replication kiʻekiʻe o nā hale paʻakikī ma o ke kaʻina hana kahiko a maikaʻi hoʻi.hoʻolei kālā. AISI 316L kila kila, ma ke ano he lala o kaaustenitic stainless steelmoʻo, kū i waena o nā mea kila kuhili ʻole no kona kūpaʻa ʻana i ka corrosion maikaʻi loa, ke kūpaʻa wela kiʻekiʻe a me nā waiwai mechanical maikaʻi. Ma hope o ka hoʻohui ʻia ʻana o ka molybdenum, ua hoʻonui nui ʻia kona hiki ke pale aku i ka lua, crevice corrosion a me stress corrosion cracking, e hoʻolilo i kēia mea i mea makemake nui ma nā ʻano he nui e like me ka ʻoihana kemika, ka hoʻoponopono meaʻai, a me ka ʻenekinia moana.

ʻO ka haku melemele a me ka microstructure

Hoʻoponopono maikaʻi ʻia ka hui ʻana o ke kila kila AISI 316L e hōʻoia i kona ʻano kino maikaʻi loa. ʻO ka haʻahaʻa kalapona haʻahaʻa (≤0.03%) e pale pono i ka pilikia o ka corrosion intergranular i ka wā wili a hoʻomaikaʻi i ka pale ʻana o ka corrosion o ka mea. ʻO nā mea kiʻekiʻe o ka chromium (16.5% -18.5%) a me ka nickel (12% -15%) e hāʻawi i ka mea maikaʻi loa i ka pale ʻana i ka oxidation a me ka paʻakikī, ʻoiai ʻo ka 2% -3% molybdenum maʻiʻo e hoʻomaikaʻi maikaʻi i kona kūpaʻa ʻana i nā kaiapuni chloride. Eia kekahi, ʻo ka nui kūpono o ka nitrogen (≤0.10%) e hoʻonui hou i ka ikaika a me ka paʻakikī o ka mea me ka ʻole e kaumaha i kona paʻakikī. ʻO kēia hui pū ʻana kemika i hoʻopaʻa ʻia, i hui pū ʻia me ka microstructure maikaʻi a me ka like ʻole i hoʻokumu ʻia i ka wā o ke kaʻina hana hoʻopukapuka kālā, hiki i ka hale pahu pahu 316L ke mālama i ka paʻa maikaʻi a me ka lōʻihi ma lalo o nā kūlana koʻikoʻi paʻakikī.

Mechanical waiwai a me ka ikaika hana

Hana maikaʻi ʻia ka hale pahu pahu kila kila AISI 316L i nā ʻōlelo o nā waiwai mechanical. ʻO kona ikaika tensile ma waena o 485-620 MPa, a ʻo kona ikaika hoʻohua ma ka laulā o 170-300 MPa, ʻo ia hoʻi ma lalo o nā kūlana haʻahaʻa koʻikoʻi, hiki i ka hale ke mālama i ka kūpaʻa a ʻaʻole hiki ke hoʻololi i ka plastic deformation a i ʻole ka haki. I ka manawa like, ʻo ka elongation a hiki i 40% a me ka paʻakikī o ka hopena maikaʻi e hōʻoia i ka palekana a me ka hilinaʻi o ka hale i ka wā e hoʻokau ʻia ai nā kaumaha. Eia kekahi,ʻo ka AISI 316L ke kila kila maikaʻi loa ka paʻakikī haʻahaʻa haʻahaʻa a hiki iā ia ke mālama i nā mea mechanical paʻa i nā wahi anuanu loa, he mea nui loa ia no nā mea hana e pono ai ka hana ma nā polar a iʻole ka moana hohonu.

Ke kila 316L (AISI, ASTM, UNS) a me kāna mea like ʻEulopa X2CrNiMo17-12-2 (1.4404) ( EN )
