316L kila kila

Hoʻohui, ʻano a me nā noi

No ka hoʻomaopopo ʻana i ke kila kila 316L, pono e hoʻomaopopo mua i ka 316 kila kila.

316 he austenitic chromium-nickel stainless steel i loaʻa ma waena o ʻelua a me 3% molybdenum.Hoʻomaikaʻi ka ʻike molybdenum i ka pale ʻana i ka corrosion, hoʻonui i ke kūʻē ʻana i ka lua i loko o nā hāʻina chloride ion, a hoʻomaikaʻi i ka ikaika ma nā wela kiʻekiʻe.

He aha ka 316L Stainless Steel?

ʻO 316L ka papa kalapona haʻahaʻa o 316. ʻAʻole paʻa kēia papa mai ka sensitization (ka ua carbide palena palaoa).Hoʻohana mau ia i nā ʻāpana welded ana kaumaha (ma kahi o 6mm).ʻAʻohe ʻokoʻa kumu kūʻai ma waena o 316 a me 316L kila kila.

Hāʻawi ʻo 316L stainless steel i ke kolo kiʻekiʻe, ke koʻikoʻi i ka haki ʻana a me ka ikaika tensile ma nā mahana kiʻekiʻe ma mua o nā kila kuhili ʻole chromium-nickel austenitic.

Koho Alloy

ʻO ka inoa "L" wale nō ke ʻano o ka "kaona liʻiliʻi."Loaʻa ka 316L i ke kalapona liʻiliʻi ma mua o 316.

ʻO nā inoa maʻamau ka L, F, N, a me H. ʻO ke ʻano austenitic o kēia mau māka e hāʻawi i ka paʻakikī maikaʻi loa, ʻoiai ma nā mahana cryogenic.

304 vs. 316 Kuhili ʻole

ʻAʻole like me 304 kila - ke kila kila kaulana loa - loaʻa iā 316 ka pale ʻana i ka corrosion mai ka chloride a me nā waikawa ʻē aʻe.He mea pono kēia no nā noi waho i nā kaiapuni kai a i ʻole nā ​​noi e pilikia ai ka ʻike ʻana i ka chloride.

Hōʻike nā 316 a me 316L i ka ʻoi aku ka maikaʻi o ke kūpaʻa ʻana a me ka ikaika i nā mahana kiʻekiʻe ma mua o kā lākou 304 hoa - ʻoi loa i ka wā e pili ana i ka pitting a me ka crevice corrosion i nā kaiapuni chloride.

316 vs. 316L Ke kila kila

ʻOi aku ka carbon 316 ma mua o 316L.Loaʻa i ka 316 stainless steel ka pae waena o ke kalapona a loaʻa ma waena o 2% a me 3% molybdenum, e hāʻawi ana i ke kū'ē i ka corrosion, nā mea waikawa, a me nā wela kiʻekiʻe.

No ke koho ʻana i ke kila kila 316L, pono e haʻahaʻa ka nui o ke kalapona - pono, ʻaʻole hiki ke ʻoi aku ma mua o 0.03%.ʻO nā pae kalapona haʻahaʻa i ʻoi aku ka palupalu o 316L ma mua o 316.

ʻOiai ka ʻokoʻa o ka ʻike kalapona, ua like loa ka 316L me 316 ma nā ʻano āpau.

He maʻalahi loa nā kila kulika ʻelua, pono i ka hana ʻana i nā kiʻi e pono ai no kēlā me kēia papahana me ka ʻole o ka haki ʻana a i ʻole ka pohā ʻana, a loaʻa iā ia ke kūpaʻa kiʻekiʻe i ka ʻino a me ka ikaika tensile kiʻekiʻe.

Hoʻohālikelike ke kumukūʻai ma waena o nā ʻano ʻelua.Hāʻawi nā mea ʻelua i ka lōʻihi maikaʻi, ke kūpaʻa-corrosion, a he mau koho maikaʻi i nā noi kiʻekiʻe.

Manaʻo ʻia ʻo 316L he mea kūpono no kahi papahana e koi ana i kahi wili nui.ʻO 316, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka liʻiliʻi o ka corrosion i loko o ka weld (weld decay) ma mua o 316L.ʻO kēlā ʻōlelo, ʻo ka annealing 316 kahi workaround no ka pale ʻana i ka pala weld.

He mea maikaʻi ʻo 316L no ka hoʻohana ʻana i ka wela kiʻekiʻe, ka hoʻohana ʻana i ka corrosion kiʻekiʻe, e pili ana i kona kaulana i ke kūkulu ʻana a me nā papahana kai.

Loaʻa iā 316 a me 316L ka malleability maikaʻi loa, e hana maikaʻi ana i ke kulou ʻana, ka hoʻopololei, ke kaha kiʻi hohonu, a me ka wili.Eia naʻe, ʻo 316 kahi kila ʻoi aku ka paʻakikī me ka ikaika tensile kiʻekiʻe a me ka ductility i hoʻohālikelike ʻia me 316L.

• Na waiwai o 316L

  ʻIke maʻalahi ka 316L stainless steel ma ka nānā ʻana i kona ʻano kalapona - pono e emi iho ma mua o ka 316. Ma waho aʻe o kēlā, eia kekahi mau waiwai 316L e hoʻokaʻawale iā ia mai nā pae kila ʻē aʻe.

  Na Waiwai Kino

  He 8000 kg/m3 ko 316L a he modulus elastic o 193 GPa.Ma kahi mahana o 100°C, loaʻa iā ia ka pilina wela o 16.3 W/mK a me 21.5 W/mK ma 500°C.Loaʻa i ka 316L ka resistivity uila o 740 nΩ.m, me ka mana wela kūikawā o 500 J/kg.K.
