US 309/309S (UNS S30900/S30908) kila

ʻO TYPES 309 AND 309S he austenitic chromium-nickel stainless steels e hāʻawi maikaʻi ana i ka corrosion a me ka wela me ka ikaika maikaʻi ma ka lumi a me nā mahana kiʻekiʻe. Ua like ka Type 309S me Type 309 koe wale no ka maʻiʻo kalapona haʻahaʻa e hōʻemi ana i ka ua carbide a hoʻomaikaʻi i ka weldability.

ʻIke ʻia ʻo Alloy 309 a me 309S no ka lawelawe wela kiʻekiʻe. Hana maikaʻi kēia huila a hiki i 2000 ° F, ʻoi aku ka nui inā koi ʻia ke kūpaʻa oxidation. ʻO 309 a me 310 ke kila kila ka poʻe hana kiʻekiʻe kiʻekiʻe ma waena o nā māka kulika maʻamau i loaʻa mai kā mākou waihona. ʻO ka nickel kiʻekiʻe a me ka chromium maʻiʻo a me ka hoʻokumu ʻia ʻana o ka palaoa koʻikoʻi ka hopena i:

• Hoʻonui i ke kū'ē i ka cyclic oxidation
• Hoʻonui i ke kū'ē i ka sulfidation
• ʻOi aku ka ikaika wela kiʻekiʻe
• Hoʻomaikaʻi i ka pale ʻana i ka corrosion intergranular

ʻO 309S (UNS S30908) ke kila kila ka mana haʻahaʻa kalapona o ka huila. Hoʻohana ʻia ia no ka maʻalahi o ka hana ʻana.

ʻO 309H (UNS S30909) kahi hoʻololi kalapona kiʻekiʻe i hoʻomohala ʻia no ka hoʻoikaika ʻana i ke kūpaʻa kolo. ʻO ka hapa nui o ka nui o ka palaoa a me ka maʻi kalapona o ka pā e hiki ke hoʻokō i nā koi 309S a me 309H. Ke hoʻomehana ʻia ma waena o 1202 – 1742°F (650 – 950°C) pili ka huila i ka ua o ka pae sigma. E hoʻihoʻi hou ʻia kahi degere o ka paʻakikī ma kahi hoʻonā hoʻoheheʻe annealing ma 2012 – 2102°F (1100 – 1150°C). Hiki i ka Alloy 309 ke hoʻopili maʻalahi a hana ʻia e nā hana hana hale kūʻai maʻamau.
