SS904L AISI 904L Kila Kuʻihao (UNS N08904)

Wehewehe Pōkole:

ʻO UNS NO8904, i ʻike nui ʻia ʻo 904L, he kila kila austenitic kiʻekiʻe haʻahaʻa kalapona i hoʻohana nui ʻia i nā noi kahi i lawa ʻole ai nā waiwai pala o AISI 316L a me AISI 317L. Hāʻawi ʻo 904L i ke kūpaʻa maikaʻi o ka haki ʻana o ka pala chloride stress, ke kūpaʻa pitting, a me ke kūpaʻa corrosion maʻamau i ʻoi aku ka maikaʻi ma mua o 316L a me 317L molybdenum i hoʻonui ʻia i nā kila kila.

ʻO ke kila kila austenitic kiʻekiʻe ke kila kila AISI 904L (UNS N08904). Ke hoʻohālikelike ʻia me 316L, ʻoi aku ka haʻahaʻa o ke kalapona (C) o SS904L, ʻoi aku ka kiʻekiʻe o ka chromium (Cr), a ʻoi aku ka pālua o ka nickel (Ni) a me ka molybdenum (Mo) o316L, ka mea e loaʻa ai ke kūpaʻa kiʻekiʻe o ka oxidation wela kiʻekiʻe, ke kūpaʻa pitting, a me ke kūpaʻa i ka hoʻemi ʻana i ka waikawa (e laʻa, ka waikawa sulfuric). Hiki i ka Nitrogen (N) ke hōʻemi i ka wikiwiki o ka chromium carbide precipitation, a laila e hōʻemi ana i ka ʻike o ka sensitization, hoʻomaikaʻi pū ia i ke kūpaʻa i ka pitting a me ka crevice corrosion i hoʻokumu ʻia e nā chlorides. ʻOi aku ka hoʻohui ʻana o ke keleawe (Cu) e lilo ia i mea pono no nā ʻano āpau o ka waikawa sulfuric.

ʻOi aku ka maikaʻi o ka hana ʻana o ka Alloy 904L ma mua o nā kila kila austenitic ʻē aʻe ma muli o ke kiʻekiʻe o ka hoʻohuihui ʻana o ka nickel a me ka molybdenum. ʻAʻole magnetic ka papa ma nā kūlana āpau a he formability maikaʻi loa a me ka weldability. Hāʻawi pū ka ʻano austenitic i kēia papa i ka paʻakikī maikaʻi loa, a hiki i nā mahana cryogenic. Hoʻolaha a mālama ka ʻike chromium kiʻekiʻe i kahi kiʻiʻoniʻoni passive e pale ana i ka mea ma nā ʻano corrosive he nui. ʻAʻohe pilikia o ka intercrystalline corrosion i ka hoʻoluʻu ʻana a i ʻole ka welding ma muli o ka haʻahaʻa o ke kalapona. ʻO kona mahana lawelawe kiʻekiʻe loa ma 450°C. He mea pono loa kēia papa i nā noi paipu kaohi a me nā mea hana kahi i kūpono ʻole ai ʻo 316 a me 317L.

Ua hoʻomohala mua ʻia ʻo Alloy 904L e kū i nā kaiapuni i loaʻa ka waikawa sulfuric dilute. Hāʻawi pū ia i ke kūpaʻa maikaʻi i nā waikawa inorganic ʻē aʻe e like me ka waikawa phosphoric wela a me ka hapa nui o nā waikawa organik.

Hoʻopilikino maʻalahi ʻia a hana ʻia ka Alloy 904L e nā hana hana hale hana maʻamau.

Hoʻohana ʻia ke kila kila 904L (SS904L) i ka ʻaila, kemika, ka mea hoʻouluulu, nā hale kiaʻi hoʻomohala moana, nā pahu wai, nā paipu a me nā ʻōmole a me nā mea hoʻololi wela. Hoʻohana pū ʻo Rolex a me nā mea hana uaki ʻē aʻe iā ia e hana i nā uaki
