317L Kūleʻa kila
ʻO 317L kahi molybdenum, haʻahaʻa carbon maʻiʻo "L" papaaustenitic stainless steele hāʻawi i ka hoʻomaikaʻi ʻana i ke kūpaʻa corrosion ma luna o 304L a me 316L mau kila kila. Hāʻawi ke kalapona haʻahaʻa i ke kū'ē i ka sensitization i ka wā wili a me nā kaʻina hana wela ʻē aʻe.
317L ʻaʻole magnetic ma ke kūlana annealed akā hiki ke lilo i mea hoʻokalakupua ma muli o ke kuʻi ʻana.

Loaʻa i ka 317L ke kūpaʻa corrosion maikaʻi loa i ka nui o nā kemika, ʻoi aku ka nui o nā kaiapuni chloride acidic e like me nā mea i loaʻa i ka pulp a me nā wili pepa. Hoʻonui ʻia nā pae o chromium, nickel a me molybdenum i hoʻohālikelike ʻia me 316L stainless steel e hoʻomaikaʻi i ke kūʻē ʻana i ka lua chloride a me ka corrosion maʻamau. Hoʻonui ke kū'ē me ka molybdenum alloy content. Kūpaʻa ʻo 317L i ka ʻakika sulfuric a hiki i ka 5 pākēneka ma nā mahana e like me 120°F (49°C). Ma nā mahana ma lalo o 100°F (38°C) he kūʻē maikaʻi kēia huila i nā haʻina o ka ʻike kiʻekiʻe. Eia nō naʻe, ʻōlelo ʻia nā hoʻokolohua lawelawe e helu i nā hopena o nā kūlana hana kūikawā e pili ana i ka hana corrosion. I loko o nā kaʻina hana i hiki mai ai ka condensation o nā kinoea sulfur-bearing gas, 317L ʻoi aku ka kūʻē i ka hoʻouka ʻana ma kahi o ka condensation ma mua o ka alloy 316. nā hoʻokolohua.
