UNS S31703 kuhiliʻole

ʻO 317L ka molybdenum-bearing austenitic stainless steel me ka piʻi nui ʻana o ke kūʻē ʻana i ka hoʻouka kaua kemika e like me ka chromium-nickel austenitic stainless steels maʻamau e like me Type 304. Hāʻawi pū ʻo 317L alloy i ke kolo kiʻekiʻe, stress-to-rupture, a me ka ikaika tensile i nā mahana kiʻekiʻe. ma mua o nā kila kuhili ʻole maʻamau. He kalapona haʻahaʻa ka alloy e hāʻawi i ke kū'ē i ka sensitization i ka wā wili a me nā kaʻina hana wela. Kuhi ʻia kēia huila no nā kūlana lawelawe koʻikoʻi e like me nā ʻōnaehana flue gas desulfurization (FGD).

Na Mea Mechanical Ma'amau- Ke kila kila 317L

317L(1.4438) Waiwai Nui

ʻO Alloy 317LMN a me 317L he molybdenum-bearing austenitic stainless steel tube me ka hoʻonui nui ʻana i ke kūʻē ʻana i ka hoʻouka kaua kemika i ka hoʻohālikelike ʻia me ka paipu kila chromium-nickel austenitic maʻamau e like me Alloy 304. Eia kekahi, hāʻawi nā 317LMN a me 317L alloys i ke kiʻekiʻe kiʻekiʻe. -ʻokiʻoki, a me nā ikaika tensile i nā mahana kiʻekiʻe ma mua o nā kila kuhiliʻole maʻamau. He kalapona haʻahaʻa a i ʻole "L" nā māka e hāʻawi i ke kū'ē i ka sensitization i ka wā wili a me nā kaʻina hana wela.

Hōʻike ka "M" a me "N" i nā mea i hoʻohui ʻia i nā pae kiʻekiʻe o ka molybdenum a me ka nitrogen. ʻO ka hui pū ʻana o ka molybdenum a me ka nitrogen he mea maikaʻi loa ia i ka hoʻonui ʻana i ke kūʻē ʻana i ka lua a me ka ʻāʻī ʻana, ʻoi aku hoʻi i nā kahawai kaʻina i loaʻa nā waikawa, chlorides, a me nā pūhui sulfur i nā wela kiʻekiʻe. Hoʻohana pū ka Nitrogen i ka hoʻonui ʻana i ka ikaika o kēia mau alloys. Hoʻolālā ʻia nā ʻāpana ʻelua no nā kūlana lawelawe koʻikoʻi e like me nā ʻōnaehana flue gas desulfurization (FGD).

Ma waho aʻe o ka pale ʻana i ka corrosion maikaʻi a me nā waiwai ikaika, nā Alloys 316, 316L, a me 317L Cr-Ni-Mo alloys e hāʻawi pū i ka fabricability maikaʻi loa a me ka formability e like me ke ʻano o ka austenitic stainless steel tubing.

Hāʻawi ʻia ka paipu kila kuhili ʻole austenitic ma ke kūlana annealed wili i mākaukau no ka hoʻohana. Pono paha ka mālama ʻana i ka wela i ka wā a i ʻole ma hope o ka hana ʻana no ka wehe ʻana i nā hopena o ka hoʻokumu ʻana a i ʻole ka hoʻoheheʻe ʻana i nā chromium carbide precipitated ma muli o ka ʻike wela. No nā Alloys 316 a me 317L ua hoʻokō ʻia ka anneal solution ma ka hoʻomehana ʻana i ka 1900 a 2150°F (1040 a 1175°C) ka wela wela a ukali ʻia e ka hoʻoluʻu ʻea a i ʻole ke kinai wai, ma muli o ka mānoanoa o ka ʻāpana. Pono e lawa ka wikiwiki o ka hoʻoluʻu ʻana ma waena o 1500 a 800°F (816 a 427°C) i mea e pale ai i ka hoʻihoʻi hou ʻana o nā chromium carbide a hāʻawi i ke kūpaʻa maikaʻi loa. I kēlā me kēia hihia, pono e hoʻomaʻalili ʻia ka metala mai ka wela annealing i ka wela ʻeleʻele ma lalo o ʻekolu mau minuke.

ʻO 317LMN a me Alloy 317L mau kila kila hiki ke hoʻopili ʻia i ka pae wela 1975-2150 ° F (1080-1175 ° C) a ukali ʻia e ka ea anuanu a i ʻole ke kinai wai, ma muli o ka mānoanoa. Pono e hoʻopili ʻia nā papa ma waena o 2100°F (1150°C) a me 2150°F (1175°C). Pono e hoʻomaha ʻia ka metala mai ka wela hoʻoheheʻe ʻana (mai ka ʻulaʻula/keʻokeʻo a i ʻeleʻele) ma lalo o ʻekolu mau minuke.
