ʻO Type 317L kahi ʻano kila kila austenitic haʻahaʻa haʻahaʻa o Type 317 e hāʻawi ana i ka pale ʻana i ka corrosion ma mua o Type 304/304L. ʻO kekahi o nā pono nui ʻē aʻe o Type 317L e komo pū ana:
- ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion ākea a me ka localized i hoʻohālikelike ʻia me 316/316L kila kila
- Maikaʻi formability a weldability
- Hoʻonui i ke kūʻē ʻana i ka hoʻouka kemika mai nā waikawa
- ʻO ka maʻiʻo kalapona haʻahaʻa e alakaʻi i ke kū'ē i ka sensitization ke welded
- Non-magnetic
E like me nā kila kila a pau, loaʻa i ka Type 317L kahi hui kemika kūʻokoʻa e pili ana i kēia:
- Fe Kaulike
- Cr 18-20%
- Ni 11-15%
- Mn 2%
- ʻO 0.75%
- C 0.03%
- N 0.1%
- S 0.03%
- P 0.045%
Ma muli o nā pōmaikaʻi Type 317L a me ka hoʻohui kemika, hoʻohana nui ʻia ia i nā ʻoihana like ʻole no nā noi he nui e like me:
- ʻO nā mea hana pepa a me ka pulp
- ʻO ka hana kemika a me ka petrochemical
- ʻO ka hana meaʻai
- ʻO ka hana mana me nā wahie fossil a me ka nuklea
- Pūnaehana desulfurization o ke kinoea
