ʻO nā paipu kila kila 904L. ʻO UNS N08904, 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. He kūpaʻa loa kēia austenitic kiʻekiʻe-alloy i ka hoʻouka ʻana mai ka waikawa sulfuric diluted, ka waikawa phosphoric a me ka waikawa acetic. Kūʻē ia i ka pitting i loko o nā hopena chloride neutral. ʻOi aku ka maikaʻi o kona kūpaʻa i ka haki ʻana o ka corrosion stress i kekahi mau chloride wela ma mua o nā austenites nickel haʻahaʻa. Loaʻa i kēia kila ka formability maikaʻi a me ka weldability. Loaʻa kēia mea i nā kūlana maʻamau e like me ASTM a me EN, akā naʻe me kekahi mau ʻokoʻa. Hoʻokomo ʻia nā hoʻoluhi hoʻolālā a hiki i ka 370°C i ASME II.
