pae 317LMN kila kila

ʻO Alloy 317LMN (UNS S31726) he austenitic chromium-nickel-molybdenum stainless steel me ka pale ʻana i ka corrosion ma mua o 316L a me 317L. ʻO ka maʻiʻo molybdenum kiʻekiʻe, i hui pū ʻia me ka hoʻohui o ka nitrogen, hāʻawi i ka huila me kona hoʻoikaika ʻana i ka corrosion, ʻoi aku hoʻi i loko o ka chloride acidic i loko o ka lawelawe. ʻO ka hui pū ʻana o ka molybdenum a me ka nitrogen e hoʻomaikaʻi i ke kūpaʻa ʻana o nā alloys i ka pitting a me ka crevice corrosion.

ʻO ka maʻiʻo nitrogen o Alloy 317LMN hana ma ke ʻano he mea hoʻoikaika e hāʻawi iā ia i ka ikaika hua kiʻekiʻe ma mua o 317L . ʻO Alloy 317LMN kahi haʻahaʻa kalapona haʻahaʻa e hiki ai ke hoʻohana ʻia i ke kūlana as-welded me ka ʻole o ka chromium carbide precipitation ma nā palena palaoa.

ʻO Alloy 317LMN ʻaʻole magnetic i ke kūlana annealed. ʻAʻole hiki ke hoʻopaʻakikī ʻia e ka mālama wela, ma ka hana anu wale nō. Hiki ke hoʻopaʻa maʻalahi a hoʻopaʻa ʻia e nā hana hana hale kūʻai maʻamau.
