AISI/SUS 309 STEEL COIL/SHEET

ʻO nā kila kila he mau kila kila kiʻekiʻe a ʻoi aku ka nui o ke kūpaʻa corrosion i hoʻohālikelike ʻia me nā kila ʻē aʻe ma muli o ka nui o ka chromium. Ma muli o ko lākou ʻano crystalline, ua māhele ʻia lākou i nā kila ferritic, austenitic, a me martensitic.

Loaʻa i ka papa 309 ke kila kila kila kiʻekiʻe ke kūpaʻa a me ka ikaika i hoʻohālikelike ʻia me 304 kila kila. Hāʻawi ka ʻikepili ma lalo nei i kahi hiʻohiʻona o ka pae 309 stainless steel.

Na Waiwai Nui

ʻO Alloy 309 (UNS S30900) he kila kila austenitic i hoʻomohala ʻia no ka hoʻohana ʻana i nā noi pale ʻana i ka wela wela. Kū'ē ka alloy i ka oxidation a hiki i 1900 ° F (1038 ° C) ma lalo o nā kūlana non-cyclic. ʻO ke kaʻa kaʻa wela maʻamau e hōʻemi i ka pale ʻana i ka oxidation ma kahi o 1850°F (1010°C).

Ma muli o kona kiʻekiʻe chromium a me ka haʻahaʻa nickel maʻiʻo, Alloy 309 hiki ke hoʻohana i ka sulfur i loko o nā ea a hiki i 1832°F (1000°C). ʻAʻole ʻōlelo ʻia ka alloy no ka hoʻohana ʻana i nā lewa carburizing kiʻekiʻe no ka mea e hōʻike ana i ke kūpaʻa haʻahaʻa wale nō i ka lawe kalapona. Hiki ke hoʻohana ʻia ʻo Alloy 309 i ka oxidizing liʻiliʻi, nitriding, cementing and thermal cycling applications, ʻoiai, pono e hoʻemi ʻia ka wela o ka lawelawe.

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).

ʻO 309S (UNS S30908) ka mana kalapona haʻahaʻa 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.

Hiki i ka Alloy 309 ke hoʻopili maʻalahi a hana ʻia e nā hana hana hale kūʻai maʻamau.
